Hi guys,got an alarming problem,whilst driving the car tonight,i noticed a faint burning smell,followed by smoke or steam coming out the air vent onto the window,it had that burning antifreeze smell i think!

Any ideas what it could be?is it safe to drive as it is?

If it smells like coolant and leaves a film on the window then its probably the heater core. Is the passenger side carpet wet?

You can bypass the heater core by connecting the 2 heater hoses together. I replaced my heater core last year. It wasnt hard to do, just very frustrating and time consuming. The heater core is only about $50, but if you took it to a garage the labour will kill you.

The 2 heater hoses are under the hood and under the coolant reservoir. It is easier to bypass the heater core but then you wouldn't have any heat obviously.

I'm not sure what you mean by bonnet, but the 2 hoses are under the coolant reservoir.

Hi, I did the by-pass on my 79 coupe , before I sold it I replaced the heater core, seats had to come out, dropped steering wheel, removed entire dash and ducting, if I were to keep the car, which would be strictly fair weather use, I would just by-pass the core , the dash stays cooler also. I only repaired it because everyone wants a heater that works..........

"Bonnet" is Queen's English for hood. :) So yes Mikey, under the bonnet.

Can't imagine why anyone would want a working heater. ;shrug:)

Yep,thats english for hood!!Got to get used to the "american" versions!!

So,is the bypass pipe something i need to make myself,or can you just buy one?If not,whats best to use to make one?

Thanks again!!
