What comes to your mind when one mentions the Toyota engines?

Common answers could include the 1UZ or the 2JZ. However, you may have also come across the obscure 2GR-FE.

This engine has been in use in various Toyota, Lotus, and Lexus models from 2005 to the present.

Despite being lesser-known, it has several unique features, which makes it worthy of observation for manufacturers. However, it is far from perfect.

The most common Toyota 2GR-FE engine problems you are expected to run into are:

  1. Oil Leak Due To Iron To Rubber Design
  2. Idler Pulley And Loud Rattling Noises
  3. Spark Plugs And Ignition Coils
  4. Water Pump And Leaking Coolant

As is evident, these issues make the 2GR-FE engine far from perfect. Once, however, I elaborate upon these issues, you can see whether this particular engine is suitable for your needs.

The 4 Most Common Toyota 2GR-Fe Engine Problems

Let's find out how good the Toyota 3.5L V6 engine is

In this section, let us turn our attention to the issues listed above.

I will elaborate on the issues prevalent within this engine and then look at possible symptoms and repairs.

So without further ado, let us get right into it!

1. Oil Leak Due To Iron To Rubber Design

The Main Problem

So, what makes a 2GR-FE Engine prone to oil leaks?

Firstly, it is a known fact that leaks can arise from a variety of areas.

The reader may also be acquainted with oil leaks due to their common occurrences and long-term implications on engine health.

The oil tube present in the VVTi lubrication system of the 2GR-FE is designed with a rubber and iron hose.

Since the rubber begins to wear away relatively easily due to its material properties, it is plausible that leaks can occur.

This becomes a prominent problem because the oil feeding system itself is vulnerable.

Fortunately, Toyota has noticed this issue and made modifications to their engine in the post-2010 models.

This means that 2GR-FE models released after 2010 include a metal hose rather than a rubber one.

It is therefore advisable to replace your rubber hose with a metal one as a preventative maintenance measure.

A hose failure can lead to a drastic loss in oil pressure, which is not right for the engine.

While it is not meant to be a scare, a replacement is a good way to prevent this issue from hurting your engine’s health.

Spotting The Issue

How do you recognize such oil leaks?

The answer is simple: Like any oil leak, the standard symptoms must be adopted when identifying the issue and its extent.

A leaking rubber hose may be spotted by:

  • Less Oil Pressure.
  • Decrease in Engine Oil.
  • The emission of smoke from the engine.
  • A visible leak.

The extent of the leak can also be identified as standard oil leaks usually are. For instance, a relatively small leak may lead to small oil drops or the production of smoke.

In contrast, a larger leak may be unexpected and can cause large drops in oil pressure. Such large-scale leaks must be repaired immediately to avoid complete engine failure.

Repairing The Issue

If you have a rubber hose on your VVTi system, your first job is to replace it with a metal hose.

This can cost somewhere around $20-40, and additional labor expenses can vary from $150-300 depending on the repair shops.

Oil leaks can also be handled by using a stop leak additive or high mileage oil blend. These products can soften and fix rubber seals to avoid further locomotive leakage.

2. Idler Pulley And Loud Rattling Noises


Does your engine sometimes produce loud, rattling sounds which incite irritation?

Chances are, there is a problem with the idler pulley in the engine. The 2GR-FE models manufactured up until 2009 also reportedly have suffered from such annoyance.

Why is that?

According to Toyota, the likely source of this noise is a worn no.2 Idler Pulley. This pulley requires replacement which can be another source of irritation for the car owner.

Despite not having massive ramifications on the overall driving and engine health, this issue requires maintenance to stimulate a better driving experience.

Spotting The Issue

As indicated above, the symptoms which can indicate a faulty Idler Pulley include:

  • Rattling.
  • Squeaking.

Asides from this, loud noises can occasionally prop up, which indicates that a repair is required.

However, such repairs need not be urgent since the worn-out pulley does not impact performance in a very negative way.

At most, the car owners can look towards repairs if they believe that their budget is more than enough to accommodate them.

This is because a worn-out Idler Pulley only impacts driving experiences and do not significantly impact the streamlined functioning of the engine.

Repairing The Issue

If the car owner does decide to engage in repair, the most adaptable solution available is the heavy-duty Idler Pulley released by Toyota for 2GR-FE models post-2010.

Again, it is apparent that this issue prevails amongst the older versions of this engine.

On the market, this is available for around $40-50, and it isn’t very difficult to do the replacement by yourself.

Since there are different amounts of pulley required for each car model, research is pivotal.

For instance, the Highlander uses electric power steering, so it only possesses one Idler Pulley. On the other hand, Avalon and Sienna models use two.

3. Spark Plugs And Ignition Coils

The Main Problem

When exploring engine capabilities, you are likely to ask the following question: how does an engine fare when it comes to engine power and efficiency maintenance?

This question is usually asked about the maintenance of spark plugs and ignition coils.

Premature ignition coil failures and worn-out spark plugs require standard maintenance for any engine without exception.

What matters then is how much an engine can go without causing major mishaps on this front.

Unfortunately, the 2GR-FE engine can, at times, have frequent problems with its efficiency.

While the usual replacement may be done at 150,000 miles, this Toyota engine may fall short of this average.

Since the 2GR-FE model is a 3.5L V6 engine, supercharged models and fine-tuning can demand quicker repairs.

This is because the extra boost and power can lead to greater wear and tear.

This means that replacements may be required after 100,000 miles. If the problem isn’t handled immediately, the result will be an overall decrease in power and efficiency.

Spotting The Issue

In the case of a problem, it is fairly easy to spot the issue due to the indications given by the engine.

Symptoms include:

  • Misfires and Sparks.
  • Rough Idle.
  • Stuttering.
  • Power loss.

As usage continues, these can start misfiring and become less effective. This will lead to noticeable stuttering or the development of a rough idle.

There is bound to be a decrease in overall engine power and efficiency of the 2GR-FE as well. However, due to this happening over a long period, it may be difficult to notice.

Fixing The Issue

The repair of spark plugs can be made in complete sets once even one of the plugs displays signs of wearing. Usually, this happens after they have been used for over 100,000 miles.

Since the importance of spark plugs exceeds that of ignition coils, it is pivotal to focus on the former’s long-term sustainability.

Replacing all the ignition coils after signs of wear is not a bad idea either. Owners may be reluctant to do this since ignition coils tend to be quite expensive compared to spark plugs.

Consequently, a complete replacement of ignition coils should only be done where the budget isn’t significantly affected.

The replacement labor costs are not very high either, since this task doesn’t require any complex mechanisms.

4. Water Pump And Leaking Coolant


This leads me to the last main concern that can arise within this model. Since a water pump is a wear and tear part, failures can occur on any car model, including the 2GR-FE engine.

There are varying extents of what can classify as an issue with the pump or a complete failure.

If there is a visible coolant leakage from the pump that can mean a simple repair of a pump is possible.

If the engine begins to overheat due to massive levels of leakage, a replacement must be done.

When it comes to engines, overheating is an intolerable feature. Unfortunately, it can be very common with old Toyota models and so require monitoring and maintenance.

Spotting The Issue

There are several symptoms that may be associated with a failure in the water pump:

  • Overheating.
  • Steam from the Engine.
  • Coolant Leak.

The type of repair that should be carried out depends on the extent to which a water pump may have worn out.

If there is a visible coolant leakage on the ground that leakage indicates that repairs should be carried out. This should be done immediately so as to avoid larger and costlier issues.

For instance, if the pump completely fails, then the 2GR-FE will begin to suffer from internal overheating and emission of steam.

The latter can happen when leaked coolant falls onto the hotter parts of the engine. If this happens, then it is incumbent upon the owner to repair as quickly as possible.

This is because the car cannot be driven until and unless the problem of overheating is resolved.

Fixing The Issue

You may have noticed a trend during the discussion of all these issues.

My point is that there is a visible attempt by Toyota to outmode these issues by creating newer models of the 2GR-FE, which are more resistant to failures.

The pump update in the post-2010 versions of this engine ensures that failures are more uncommon for car owners. However, the repair replacement in itself is quite costly.

A replacement pump costs somewhere around $150, and the additional labor costs are at an upward of 300$.

This is because the task of actually fixing and repairing a water pump is quite challenging as compared to the other issues listed above.
