Foam

[BatleyBoy]

The foam between the radiator and the car body keeps falling out. I've repalced it with some sticky back foam, but that keeps falling out as well.
Any suggestions...... In fact do I need to repalce it?

Often wondered about this. Mine is only half falling out and I keep putting it back.

Not sure of the implications of not having it except for the gap between the rad and bodywork. I guess just more cold air will flow over in to the engine bay.

Pretty sure Mr. Heath or Humphries will be along in a moment.

Mate.

Might have something that will solve the problem, I'll check at the factory tomorrow.

It's a black expanding foam tape about 25mm wide that sticks to things like the preverbial to a blanket!

BTW have I told you I've moved..... Back to Sussex

Nice touch mate.

To get decent cooling system performance when it's stationary you need to make sure that no hot air coming out of the rad can nip back around to the front and get sucked in for another go. Gaps round the side of the rad are a prime favorite for this, and if you work out the area it doesn't take much of a gap to produce a sizeable amount of leakage.

Bugger! s'pose I'd better put the tatty piece of crap back then!

Was just thinking the same. Although even on the hottest days I never have any trouble.

The piece of foam blew out of mine and landed on the exhausts about a week after I bought it. Terrible smell of burning. I never replaced it, and it's been fine ever since, so I never bothered doing anything about it.

My rad is at a slight angle to the body and the foam kept coming out.
Dream Machines got me a double length and I just doubled it where the widest gap was - it hasn't moved since.
The temp stayed smack on 90 all day at LT so it must be working OK

Mine did the same. However, I was in a petrol station at the time - the attendant was not too impressed by the volume of smoke coming out of my engine bay!
