Seal between Firewall and Blower Motor

[DrtyJack75]

I pulled my heater core out today, replaced it then replaced (or attempted to) all the seals. Well when I went to put the blower motor seal in, it doesnt fit so well.

Does anyone know if the flat part faces the firewall or the blower?

The PICTURE on the instruction makes it look like the flat part goes against firewall but when you tighten everything up it makes the flat part flare out and look kind of weird.


Anyone do this and know what Im talking about???

THANKS!

Yes , the flat part should be against the firewall. What is the temp like where you are working on it? If it is cool you might need to warm up the seal when you install it.

well it's fitting fine but the flat part is tappered on the inner part of the whole, so when you tighten it up....it bows out the flat part....

damn should of taken a picture...

This is how it looks on the box before assembly. It should fit flat against the fire wall once it's installed.

wow mine does NOT look like that...Mine is completely flat on the side that's facing the camera in the picture. And it's beveled on the inner part of the circle

The ones we have at the store looks just like the one sport/truck has.

I cant think of how to explain this...but see how that one looks like the whole thing curves in or belled....mine is flat around the outside and then it has the inner beveled part....

I think you have the original foam type. They are BUTTCO IMO. The rubber is a high quality unit and should last a life time.
Here is a picture of my old one. Is this what yours looks like?

I wish I had the space to work on my truck at home so I could go outside and just get a picture but unfortunately thats not the case..

Ill get a picture tomorrow....mine are rubber but mine are FLAT on the side that goes up to the firewall, not like a suction cup shape like those appear to be

What you want is a seal thats going to flex and take shape to the fire wall once it's installed. The new one looks flat after I put it on. I don't have a clear picture of it put maybe this will help.

I have the rubber one also & it flares outward as well. I tried both ways, still the same. So, it seals & doesn't leak, works for me......moving on.....
