Upgrading Your Toyota From A Plastic Oil Filter Cap or Housing To a Far More Durable Aluminum Unit

A number of years back, Toyota decided to move from the old spin-on canister-type oil filters to the use of cartridges encloused in a housing. The cartridge is really just the filter element so that’s what get’s tossed, burned, recycled or whatever and the housing is re-used. The problem is that they made the cap of the housing out of some form of polymer and it can crack or chip over time.

In the case of my daughter’s 2013 RAV4 XLE, the polymer cap was chipped near the bottom (closest to the road) and was starting to crack. We bought it when it was returned to the dealer at the end of a lease so who knows who was doing the oil changes or how much they cared.

At any rate, it puzzles me why Toyota went with Polymer. Maybe they wanted to to be softer than the aluminum. Maybe it was cheaper …. not really sure. On one hand you could validly argue that the cap lasted almost 10 years. On the other … it’s polymer and can crack. After asking around, friends recommended I move to an aftermarket aluminum housing to avoid future problems.

I did some digging on Amazon and sure enough, there was a surprisingly affordable aluminum replacement unit that got very good reviews. It’s made in China and sold by “RJSPHH” with 4.9 stars and a relatively few 20 reviews. Normally I would want more reviews but gambled and it paid off. Here it is:

What Toyota Part Numbers Does It Replace?

RJSPHH figured out that by having the same cap and different filter tubes internally, they could cover quite a few Toyota oil filter caps for Avalons, Camrys, RAV4s, Tacomas and more – you actually need to go to their Amazon listings to see all of them. The Toyota oil cap part numbers this particular model can replace are:

15620-0S010, 15620-31040, 15650-38050, 15620-31050, 15650-38010, 15620-31060, 15620-38010, 15620-36020, 15650-38020

I’d recommend you confirm the part number your vehicle uses by looking up the part number on the Toyota parts website or by using your favorite parts website. This way to can verify both by year and model as well as the OEM filter canister part number just to confirm. For example, I used the Toyota site and confirmed the housing or “cap assembly, oil filter” as they call it is part number 15620-36020. I could then confirm that number on the Amazon listing. That was good because they didn’t list the XLE trim level in the Amazon post. Sometimes those details matter and sometimes they don’t – in this case it didn’t.

How To Assemble It?

In the Amazon listing, they tell you which of the three lengths of tubes to use. You can also just set your original housing assembly next to the new RJSPHH unit and figure that out in a hurry too.

They do have a brief video and assembly in the video. I watched that and the only thing that threw me for a minute was the actor was holding an o-ring at one point when putting the base plate in that the spring sits in. I’m pretty sure that was a spare o-ring for the small cap that can be removed to drain the oil from the canister first if you want to. You don’t use it when installing the tube.

The cap is nicely wrapped and you can see the three tubs that come with it. All of the parts are well made and do not feel weak or cheap.
The drain plate on the left goes on the bottom with the flanged portion facing up to cup the spring in place. The tube of the correct length is then pushed down, rotated into position and released. The filter cap is then assembled.
When you push down the tube, rotate it so the tab goes between two holders on each side of the casting.
I like using Wix brand filters. Here is the 57047XP cartridge for the 2013 2.5L Rav4. It comes with new O-rings both for the the main canister of the cap as well as the small drain plug / drain cap on the end. Even though the Chinese cap came with new O-Rings, I saved them for later just in case and used the brand new O-Rings from Wix.
By the way, make sure the drain cap/plug is on. In case you didn’t know it, that cover with the 3/8″ socket square in it comes off and is used to drain the cap. It should have an O-ring behind it and that o-ring is something you replace when you change the oil. Make sure the O-ring is there and that plug is snugged down so the O-ring can seal.
If you don’t have one, get the correct oil filter wrench to engage the cap assembly correctly to remove it. This is a Motive 2320 that I have used for years and it works great. There are many other wrenches out there as well.

Summary

This is a solid part. It fit easily with no fitting required on my daughter’s RAV4 and we haven’t had any problems. If you are looking to replace a polymer unit on your Toyota vehicle and are considering this one, I have no hesitation recommending it.


Note, I have to buy all of my parts – nothing here was paid for by sponsors, etc. I do make a small amount if you click on an ad and buy something but that is it. You’re getting my real opinion on stuff.
