#1: Exhaust problem Author: LiamGTi180, Location: OxfordPosted: Sun Nov 06, 2011 4:54 am ---- Ever since i replaced my radiator there has been alot of white gas (steam i think) coming from the exhaust. What would have caused this? It disappears when the car gets warmer
#2: Re: Exhaust problem Author: panzer360gti, Location: UKPosted: Sun Nov 06, 2011 5:05 am ---- Steam, especially on a cold day!
#3: Re: Exhaust problem Author: LiamGTi180, Location: OxfordPosted: Sun Nov 06, 2011 5:16 am ---- it never did it this bad before though. As i drive i can see it behind the car
#4: Re: Exhaust problem Author: 206racer, Location: derbyshirePosted: Sun Nov 06, 2011 5:38 am ---- I can see steam from my exhaust when the engine is cold but once warmed up it goes.

#7: Re: Exhaust problem Author: LiamGTi180, Location: OxfordPosted: Sun Nov 06, 2011 10:18 am ---- ok its obviously in excess overwise i wouldnt be moaning about it. just wondered if it could be connected to the radiator replacement
#8: Re: Exhaust problem Author: Lee, Location: EnglandPosted: Sun Nov 06, 2011 10:21 am ---- Your excess is different to my excess which is different to panzer360gti.....etc
If you aren't losing water then it's just steam

I always think that a bit of water vapour on start-up is the sign of a good AFR

I'll have a look at my exhaust smoke tomorrow morning when its really cold, and see if its excessively so, or just more than I'd get when its a bit warmer.
the point being, large amounts of smoke (well, clouds of condensed water vapour) are not unusual and nothing to worry about; but if there is another issue to do with the recently replaced radiator, then obviously further investigation is needed. I'd not be too worried though, since the radiator and exhaust are not connected - the coolant system is a sealed system with recirculating coolant, and the path of intake air - engine (cylinders) - exhaust is a separate path. The only places they'd come together is in fault conditions such as a blown head gasket - but not a faulty radiator.

On starting my engine, there was a large quantity of white water vapour. I also looked at many other cars on the roads, all emitting lots of white cloudy vapour from their exhausts. I also checked the quad, the telehandler and 3 tractors at work - so a mix of petrol and diesels there - all the same.
#14: Re: Exhaust problem Author: LiamGTi180, Location: OxfordPosted: Mon Nov 07, 2011 11:18 am ---- ok thank you for your help everyone. just hoping that there's not a blown gasket. could it have anything to do with my new induction kit?
