Coolant smell

[cmoth 0]

Hi

Ive had just joined this forum as I purchased a corrado VR6 a couple of weeks ago.

I previously owned one 6 years ago and compared to my current one, I think its far to say it was a dog as the two are like chalk and cheese.

Mt current vr6 is a M 94 plate with only one previous owner.

My question is that I can notice a smell of coolant coming into the cabin when the engine is at normal operating temperature.

I have replaced the expansion cap but it is still there although I believe not quite as bad.

Has anyone suffered this or can recommend all t he possibilities that it could be?

I have it booked in for oil and filter on Sat am so will get the garage to do a pressure test anyway, be good to have a few ideas up front.

Thanks

Col

I only really notice it when I stop at traffic lights, traffic etc. Im guessing its either heater matrix on its way out or possibly a leak from somewherein the cooling system. Just wondered if anyone has suffered this with their VR6 golf/ corrado etc.

I am not loosing any water and I know the car has had a new radioator and waterpump fairly recently.

It is quite a potent smell, I have had a few leaks recently and I always smell them before i notice any water loss. None of my leaks have been in the cabin, but I still got a strong smell. It could be anywhere, but the thermostat housing is quite prone to leak and it is quite hard to spot.

Definately potent when it waffs through the air vents although its not all the time. Im hoping the pressure test may reveal where its coming from as I dont think its anything serious as everything else about the cooling system seems to be working as it should.

Im hoping its probably a seal although knowing my luck with cars, It would not surprise me if it transpires that it is the heater matrix?

I cant see any real leaks in the engine bay and i have been cleaning it alot recently
