The Ultimate Honda J32 3.2 V6 Engine Information. The Honda J32 3.2L V6 engine first appeared in the Acura TL in 1999 as the J32A1. Several other J32 variants were produced until its final production in 2008. The horsepower ranges from 225 to 270 hp. These are impressive figures for a relatively small V6 from the early 2000s. However, no engine is perfect, and this is also true here. This guide covers Honda J32 3.2L V6 engine issues, reliability, specs, and more.
What Vehicles Make Use of the J32 Engine?
Honda/Acura 3.2 V6 engines are available in the following model years and years:
- 1999-2003 Acura TL (J32A1)
- From 2001 to 2003, Acura CL (J32A1)
- 1999-2002 Honda Inspire (J32A1)
- Acura CL Type-S (2001-2003) (J32A2)
- Acura TL Type-S 2002-2003 (J32A2)
- Acura TL 2004, 2005, 2006, 2007, and 2008. (J32A3)
J32 engines were most famous for powering the Acura TL and TL Type-S models from 1999 to 2008. It’s also in the Honda Inspire, which is based in Japan and is similar to the Acura TL models. Finally, the J32A1 and J32A2 engines are found in the Acura CL and CL Type-S. These models were only produced until 2003.
Honda J32 V6 Specifications
The Acura J32 engine specifications are as follows:
These are fairly standard specifications for a Honda J-series engine. When delving deeper into J32 specifications, nothing stands out as particularly noteworthy. To reduce weight, Honda 3.2L V6 engines use an aluminum block and head. The SOHC VTEC design enables efficient low-end performance while producing more power on the top end.
When everything is considered, the engine produces 225 to 270 horsepower. J32A1 engines produce 225hp and 217 lb-ft of torque. Acura Type-S J32A2 engines gain 260 horsepower and 232 pound-feet of torque. Improved intake, exhaust, and camshaft all contribute to increased power.
The latest J32 engine, the J32A3, powers Acura TL models from 2004 to 2008. The engine was initially rated at 270hp by Honda. However, due to changes in SAE power testing methods, it was soon reduced to 258hp. The engines are identical, despite their different power ratings.
Performance of the Acura 3.2L V6
We usually avoid discussing specific performance details. Most engines are found in far too many different vehicles to be specific. It’s a little easier with the J32 V6 because it’s primarily found in the Acura TL and TL-S. The following are some specifications from Car & Driver’s testing of these models:
- 2002 Acura TL: 0-60 in 7.4 seconds, 1/4 mile in 15.9 seconds at 90 mph
- 2002 Acura TL Type-S: 0-60 in 6.2 seconds, 1/4 mile in 14.8 seconds at 96 mph
- 2004 Acura TL: 0-60 in 5.7 seconds, 1/4 mile in 14.4 seconds at 99 mph
By modern standards, the Acura TL 3.2L V6’s performance data isn’t particularly impressive. However, for the time, these were quite good results, particularly for the J32A3 in 2004+ models. We don’t have much more to say about stock performance, so let’s look at aftermarket potential instead.
Potential Acura TL J32 Aftermarket
Many people are aware that naturally aspirated engines have limited power and torque. The Acura J32 V6 engine operates on the same principle. The J32A2 and J32A3 don’t have much extra to offer without a turbo or supercharger kit. A few bolt-ons such as an intake, exhaust, tune, and headers could help you gain 10-30 horsepower.
The original J32 engine, on the other hand, has some promise. The J32A1 is not more capable than later engines; it simply has a lower starting point. Exhaust, intake, intake manifold, and camshaft modifications allowed the J32A2 to produce 260 horsepower. With the right upgrades and a tune, similar mods can boost the Honda J32 around these levels, if not a little further.
Those looking for more than 280-290hp should consider forced induction. Going this route is not cheap, and many people prefer the older B and K series engines for boost. Having said that, there are some amazing, one-of-a-kind J32 engine builds. To get the right build, you’ll simply need a large wallet and a lot of patience/knowledge.

Problems with the Honda J32 3.2 V6 Engine
Among the most common problems with the Honda/Acura TL J32 3.2L V6 engine are:
- Main rear seal
- Timing chain
- Oil spills
We’ll go over each of these Honda J32 problems in detail throughout this article. However, before we proceed, we should make some housekeeping notes. We may not say it every time, but we believe these are the most common issues. That doesn’t necessarily imply that they’re common problems in the strictest sense of the term. Instead, when engine problems do arise, these are some of the most commonly visited areas.
Having said that, Honda J-series engines have been around for quite some time. The J32 is a solid, dependable engine with a long lifespan. Many of the problems we talk about aren’t true design flaws. However, it is an older engine, which can cause a variety of issues. At the end of the article, we’ll return to the Honda J32 reliability topic. For the time being, let’s dive right in and talk about the aforementioned common issues and failures.
1) Leaks in the J-Series J32 Rear Main Seal
The most common problem with the Honda J32 engine is rear main seal leaks. This is a fairly common issue on many different engines, so the 3.2L V6 isn’t alone here. Oil leaks from the rear main seal are also mostly caused by age and mileage. We’re not aware of any serious design flaws that are causing this leak.
Anyway, for good reason, we’ll be returning to the subject of oil leaks. Honda J32 engines are now between 14 and 23 years old. Age and mileage are hard on gaskets, seals, rings, plastics, and other components. With age, parts become brittle and crack. That is exactly the problem with the Honda 3.2 V6 rear main seal leaks.
However, main seals aren’t the only source of oil leaks. Why are we focusing on the back main seal? This is a fairly common problem, but it can also be an expensive repair. To remove the rear seal on the Acura TL, the transmission must be dropped. Although the part is inexpensive, labor can quickly add up.
Symptoms of a Honda J32 Rear Main Seal
The following are symptoms of rear main seal oil leak problems on the Honda/Acura J32 engine:
- There is a visible oil leak.
- Engine oil is low.
- The odor of burning oil
The only symptom of rear main seal failure on the Acura TL is usually a visible oil leak. If you notice oil spots on your driveway, the main seal is most likely to blame. However, don’t automatically blame the J32 rear seal. Check the oil pan, valve cover, and other basic components.
Although burning oil odors are possible, they are unlikely with a rear main seal leak. With valve cover gaskets, it is more common to smell burning oil or see light smoke coming from the engine bay. Low oil is another possible symptom. However, chances are you’ll notice the puddle of oil before the engine oil runs low.
Replacement of the Acura Rear Main Seal
Book hours for main seal replacement can vary depending on the year and model. However, it is common to receive labor quotes ranging from 10 to 12 hours to replace the rear main seal. That’s a good $600-1,000+ in labor, depending on labor rates in your area.
The Acura J32 seal can be purchased for less than $50, making it a low-cost DIY project. We recommend that you leave this job to the professionals unless you have prior experience working on cars.
2) Timing Belt Issues with the Honda J32
We don’t consider the timing belt to be a major issue on the Acura J32 3.2L engines. It’s still an important topic that we thought was worth discussing. Timing belts are a common component of vehicle maintenance. Belt replacement is recommended for Acura TL models equipped with the J32 every 8 years or 105,000 miles. Whichever happens first. Failures before that mileage are uncommon (and remain uncommon up to 125,000 miles).
Honda J32 engines, on the other hand, are interference engines. The area through which the pistons and valves travel overlaps. If the timing belt on the 3.2L V6 snaps or slips, the pistons and valves may come into contact. As a best case scenario, you’ll likely end up with some bent valves. That’s bad enough, but complete engine failure is possible. Either that, or the damage is so extensive that repairing it makes no sense.
The point is, don’t forget about the timing belt and stick to the maintenance schedule. Timing belt failures are uncommon in general, but they can be disastrous if they occur. Keep up with belt replacements, and problems become almost unheard of.
J32 3.2L V6 Timing Belt Issues
The following are some symptoms of a worn or failing timing belt on the Honda J32 V6 engine:
- Sounds such as ticking or slapping
- Misfires in the engine
- The engine light is on.
- Power decline
Timing belt failure symptoms are frequently difficult to detect before the belt snaps or slips. Visually inspecting the Acura J32 timing belt on a regular basis is a good idea, especially as it nears the end of its useful life. Wearing belts can cause ticking or slapping sounds from the engine.
Otherwise, the remaining J32 timing belt symptoms typically indicate that the belt has slipped or snapped. When this happens, misfires, power loss, engine lights, poor overall performance, and the engine shutting down are all possibilities.
Timing Belt Replacement for Honda J32
The good news is that timing belt repairs are reasonably priced. It’s standard maintenance, so Honda designs these parts to be inexpensive. We recommend replacing both the belt and the water pump at the same time. They’re in the same area, so you won’t have to pay double labor if the Honda J32 water pump fails.
Prices vary depending on where you source parts and where you repair the car, as with any repair. Most 3.2L V6 timing belt and water pump kits should cost less than $200. Add another $150-300 for a few hours of labor. Of course, the DIY crowd can save money on those costs, and moderate DIYers should have no trouble.
3) Oil Leaks in Acura TL 3.2 V6
The topic of general oil leaks on the Honda J32 V6 engine is a quick one. This is similar to the rear main seal issues mentioned above. Rubber gaskets, seals, and o-rings deteriorate with age and mileage. They become brittle, crack, and eventually leak oil.
Look for the oil pan gasket, valve cover gaskets, and front main seal outside of the rear seal. This is not an exhaustive list, but it includes some of the most common locations for J32 engine oil leaks.
Oil leaks aren’t the only problem. Engines have numerous parts that deteriorate with age and mileage. It’s not always about the distance, either. In a moment, we’ll return to this in the reliability section. It’s simply important to remember that the Honda J32 3.2L V6 is an older engine that is prone to problems as a result.
Symptoms of Honda/Acura J32 Oil Leak
Sorry for the repetition of talking about general oil leaks after the rear main seals. Again, the symptoms of J32 oil leaks are straightforward. Nonetheless, on the Acura TL 3.2 V6, look for the following signs of oil leaks:
- Visible dripping
- Oil scarcity
- The odor of burning oil
- Engine compartment smoke
If you notice visible oil spots, you most likely have a leak somewhere. Again, low oil is a possible symptom, but you should be aware of others before running out of oil. Because all engines use some oil, a low oil level does not always indicate a leak.
Burning oil odors and light smoke from the engine compartment are common symptoms of valve cover leaks. Following the rear main seals, this is most likely the next most common Honda J32 leak. The valve covers are located at the top of the engine. Oil will frequently drip onto hot components such as the exhaust manifold and burn off before it reaches the ground. Look for any engine bay smoke or burning oil odors.
Repair for Honda 3.2 V6 Oil Leak
Oil leaks aren’t always a bad thing. Although they aren’t usually urgent repairs, it’s still a good idea to fix leaks as soon as possible. This is especially true if oil is leaking onto hot parts, potentially causing a fire.
In any case, the gaskets and seals that cause J32 oil leaks are inexpensive parts. On the rear main seal, labor can be a killer, but most other leaks aren’t quite as bad. Still, depending on the leak, expect to pay $150-500 for labor and another $10-50 for parts.
Reliability of the Acura TL J32
Is the Honda J32 3.2 V6 engine dependable? Yes, we believe the engine is more reliable than average. When it comes to the J32 engine itself, there aren’t any major issues. Rear main seal leaks are common in older vehicles with high mileage. The same can be said for a couple of other oil leaks and the occasional coolant leak.
Otherwise, if you keep up with maintenance, the Honda J32 is a fantastic engine. Timing belts, for example, can cause costly damage, but it’s extremely rare if you keep up with belt replacements. Of course, perform all of the other fundamentals, such as changing fluids on time, using quality oils, and resolving problems in a timely manner.
Remember, we’re talking about a 13-22 year old engine. Many J32 engines are likely to have plenty of life left in them, but older engines are prone to a variety of issues. Fortunately, most problems are inexpensive and simple to fix. It is not uncommon for the J32 to travel over 250,000 miles with few issues. Not too shabby in terms of longevity.
