Hi all,

Sorry to make my first post here a plea for help,

But i recently bought a 96 80 series, to do a few months in some parts of Australia.

And while i am really happy with it - one problem has me a little scared, as we are about to head more remotely.

After doing speeds >~80kmph, the drivers side cabin gets really really hot. Heat seems to be eminating from the centre console & transmission, and also the handbrake, and extends through to the pedals and under drivers seat.

So while I assume it is the transmission - the car has been through 3 different Mechanics eyes since i purchased a month or two ago, had all fluids checked or changed and none can see the problem.

Any ideas, or anything anyone has seen before?

What side is the exhaust on ???.
It may have been re routed and needs to be moved or a heat guard is missing.

Hi RTM,I have had an 80s petrol since 1993, tunnel heat is a common problem with the 80 but not detrimental, the motor runs hot and the exhaust runs close to the drivers side footwell, thus the heat blowing back thru the fire wall/ console, there is no outright cure. Some take a strip out of the drivers side running board to let the heat escape, (not worth the effort), I have run 50mm flexi drain pipe x2, from the front crossmember up to the top of the tunnel near the g/box to get some cool air there, that made a little difference , also I don't have rear mufflers anymore, not quite as much back pressure, but the footwell still gets hot in summer. You will enjoy the 80, they are a great car, If you find a cure please post it on the forum. Regards Keith

Important to check the steering shaft rubber firewall gland plate- I am on third one in 400,000kms. Simple job to change and won't break the bank

Damn, you beat me to it Jaydub! Here I was going to sound like I actually knew what I was talking about!!! What about that seal on the left hand side - Was it seal around the aircon pipes where they pass the firewall?

May as well check that one while you're in there.

Hi i thought there was a problem with my 80 as well when i first got it,
thought the heater was always on.
But after a little research. and previous posts on here and other forums, found out as the other replies it appears to be normal.
Not noticeable in the cooler months .And not a big issuse in the warmer months as the aircon fixes it lol.
But i would check a few things as said like the rubber boot seal around the steering through the fire wall not hard to replace and the rubber boot between the gear shifter/box and floor there are two of these its the last one, this also lets in oil fumes and is quite common to be torn.
Also that the heater tap in the engine bay on the fire wall dose completely close.

I only ever made one mistake
and that's when I thought I was wrong!

Nothing to do with your problem but is a potential for rust. Get under the front end and on either side on the fire wall is two brackets (one either side) you will see these two bracket type things with rubber bungs in the bottom of them just in from the guard brackets holding the inner part of the guards on. From what I can gather they were there purely for the manufacturing of the body (jig assembly maybe ??) Pull the rubber grommets out and leave out, for some reason they allow water in but wont let it drain back out again which obviously lets the water sit there and will rust through the fire wall and will end up costing a nice small fortune to repair
as per pic below........................................

We have a 96 80s petrol and it is the same. I think it is just the nature of the beast and nothing to worry about in particular. We have done several thousand kays in ours now and it has always been noticably hot coming from the trans tunnell but no problem has ever reared its head as a result.

Just turn on the air con if it gets too hot and enjoy the drive.
