View Full Version : VTM-4 fluid replacement

Anything think it is that big of deal to replace the VTM-4 fluid at 15K miles. I have about 21500 on my 2004 and haven't done it yet. Was thinking about getting it done around 22500 miles.

Thoughts?

You're lucky to have a longer fluid replacement schedule. I'm on a severe condition schedule and I replaced mine at 7,500 miles, I replaced it myself.

You should replace yours as soon as you can. :)

Was wondering the same thing myself. I just bought an '05 Pilot and noticed in the owners manual that the VTM-4 fluid needs changing at 7.5/15K miles. Haven't stuck my head under the vehicle yet, but how hard is it to change that fluid? Is there a drain bold?

It's easy, almost the same as changing your engine oil. There are two plugs, the one on top is the filler hole and the bottom is the drain hole. Buy new crush seal washers, they are different sizes, just tell the guy at the parts counter that you are changing your differential fluid for your year and model of vehicle.

Just remove the drain bolt and the filler then when it's done draining, install your new washer on the drain plug bolt and tighten it to spec. Fill it up with the VTM-4 fluid until the bottom of the filler hole (double check this info first from the instructions) and install your new seal washer on the filler bolt and tighten, you're done.

The only thing is that it's a PITA being under the truck when you're doing this, I wish I was younger. I'm getting too old for this, but just trying to save some pennies for my next accessory purchase. :D

Get a $5 pump and you'll save yourself some time and aggravation.

Make sure you remove the fill plug before you remove the drain plug. You don't want to drain the diff and find out you cannot get the fill plug out. I had to put a 24" breaker bar on the fill plug to break it loose.

It's easier than changing your oil, (no filter), don't neglect it.

I am prepping for this...what is the capacity of the rear diff?

Thanks,

3Q, the rear diff fluid only comes in 1 gallon jugs. Add fluid until it starts to drain out the fill hole.

Any particular brand & weight to the oil to be used? Getting it from the dealership? (sorry, my wife has the manual and won't let me read it since it's her truck :lol: :lol: )

There is only one brand and type.

It is Honda brand, and VTM-4 Type.

It is not oil, it is special hydraulic fluid, like ATF, but with some different specs and properties.

P.S. You MUST keep it clean, so get a new differential oil pump!

Don't just wash out the old 90W with carb cleaner. :evil:

The pumps are cheap, get 1 for each of your fluids that require a pump. I have 4, but I'm servicing 3 cars, a truck and 2 tractors. I also have a dedicated funnel and spout for the ATF.

No, just start with a new one and don't use it for anything but VTM-4 Fluid.

Ok, I feel stupid now. I think I have caught on to what you were saying about a pump. You are saying a pump to pump the oil out of the bottle into the diff correct?

I was thinking a literal pump inside the diff (can you say duh?) :roll:

Been a rough week :oops:

Has anyone used a substitute oil or know of one?

There is no substitute available for the VTM-4 system. You must use genuine Honda VTM fluid from the dealer, there is NO substitute for this. You can, however, temporarily use regular ATF fluid, if you are in a bind, but that must be replaced immediately with the Honda fluid at the first available opportunity or your VTM-4 system will be toast, and no, your warranty won't cover that because you used the wrong type of fluid in the system.

There are alternates you can use, but then you have to change the whole differential instead of just the VTM-4 fluid, every 7.5 / 15K miles. :-(

Stick to the special stuff Honda recommends. The rear differential on a PILOT is a fairly complicated (and expensive) machine.

What do you mean by change the whole differential instead of just the VTM-4 fluid? :?
I thought replacing just the VTM-4 fluid addresses the whole differential system of the Pilot.
Is there some other differential component in the Pilot that I need to know other than the VTM-4 rear differential?

Some owners have tried using 'special' lubricants in their Hondas and paid the ultimate price of having to replace trannies, rear differentials, power steering, etc.

Search 'amsoil and black' as an example to see what a member named 2003 Honda CRV went through.

You're right. The VTM-4 fluid addresses the whole differential system of the Pilot.
You can use another brand of differential fluid BUT not as a permanent replacement to the Honda VTM-4 fluid. Use of an alternate brand should be temporary and the shortest possible usage. Then if possible drain and refill 3X using the Honda VTM-4 differential fluid.

Does the dealer do this for you at the set tune-ups? I have no clue if they've done it yet... and I have 31,650 miles on it!

It really depends on the dealer. Check your manual to see if your driving habits follow the "severe" or "normal" maintenance schedule. If you fall under the "severe" schedule, you're about 16K miles overdue.

Could this be the reason my gas mileage sucks so badly?

My guess would be no. Bad gas mileage is caused by many factors, but in the winter it is most likely due to a winter blend of gasoline which many have found to give poor gas mileage. It can also be due to the way the Pilot is built too; it's a large SUV.

Not if you want to get most of the old fluid out. You can get the pump at any auto parts store for about $8.

Do you need a pump to get most of the fluid out?
Does the VTM fluid not drain out completely through the drain hole?
I know you need a pump to fill up the rear differential case with VTM fluid but not to get it out.

You are correct, my bad, I was thinking of another thread for some reason. Yes, you will need one to replace the fluid, not drain it.
