CHANGING THE THERMOSTAT

1996 Pontiac Transport

Engine Cooling problem
1996 Pontiac Transport 6 cyl Front Wheel Drive Automatic 147252 miles

How do you get to the thermostat? Do you have to remove the throttle body in order to change it? I can take the air intake off, but there still is the throttle body above it making it impossible to get to.

Please help!

Thank you in Advance!

I would donate if I could!

I resently changed my water pump and I was going to do the themostat, I pulled the air box and yes I also pulled the mass air flow sensor so I could see the lower bolt but the exaust is still in the way, I tryed every tool I had socke and offset wrench nothing worked so I gave up. Sorry interested if you do get it let mw know how. Thanks j ames

Hi frank,

Can you take a picture and post it here in forum?

What I find just says you only have to remove the Air Cleaner and Duct Assembly.

Hi James,

If I am not mistaking the lower bolt hole is slotted so all you need to do is loosen it enough to pull the housing out.

I'm not sure I have the know how to place a picture of the engine on here, I might have to go to antoher forum to ask how to do that too. LOL! I will see what I can do. I'm sure glad your trying to help me out. I've been stumped for awhile. I just couldn't believe you would have to take all that off to get to the thermostat.
I have heard of people having to drop an engine just to get to something. I kinda forgot what it was they needed to replace, but you get the picture. I really hope not to have to go that far with pulling the throttle body with those cables attatched.

Thanks again!

If this is what your engine looks like, then this may be tough. i had to find this on the web and it is real small. do you know how to email the pic? you can send it to me and i will post it for you. here is what i found, but too small. what i circled in red is what i believe to be the hose you need to follow, i cannot tell for the photo is too small

Yes that is a similar engine but it is more than what I can see when I lift the hood. Oh and alot cleaner too! The hose is to the left of your circle, it has the stripe on it. If you follow that you will see it goes under that housing where the air intake hose connects to. The angle of the picture is exactley how I can see it but only about a quarter less from the top. What you can't see is the metal heat shields from the exhaust manifold. I'm sorry, the more I tell you, I'm beginning to think it is impossible for a do it yourselfer! I guess I was hoping somone had a magic button you pushed to pop it off from under all that. I do thank you for assisting me in this impossible feat though. Thanks again, like I said this was my first time asking anything over the computer. A friend just suggested it. If you find that magic button, please feel free to send it to me:)

Ok, I think we are ready to go now. Here is the proceedure.... You can press your "CTRL" key then the "+" key to zoom in to read better. If still cannot read let me know and I will email it to you.

Oh, the Bottom bolt hole of themostat housing is slotted. You don't have to remove the bottom bolt completely
