Title: engine cooling??
Post by: Sugar79 on 26 February 2014, 15:46

Hi everyone.. got a 2000 plate 2.0 mk4 golf

Problem I have with it is that the temp gauge reads the the engine is cold or slightly warm most of the time even when its been running/driving for 20mins or so..

ive had the car about 5 months.. when I first got it it was doing this.. so i changed that temp sender, didn't improve things.. also not very much heat was coming through the heater.. so I thought must be a stuck open thermo.. had thermo changed ( I even tested the new thermo in a pan of hot water to make sure it worked.. which it did) car seems to get up to temp then.. sit nicely 90c.. for about a month.. now the temp gauge is doing the same thing.. except I have lovely heat through the vent.. i have water flow back in the bottle.. all water pipes are hot after a good run.. even the one with the temp sender is hot.. feels hotter than the read out on the dash?? engine runs lovely..

Could a new sender be faulty? or could the actual dash gauge be faulty?  :sad:

I was watching the gauge closely after a run earlier.. it was sitting at I suppose at about 60c.. it would move up n down very very slightly.. then I would drive off and it would drop by a millimeter.. its all rather odd.. I don't think there is a problem with the engine.. specially since I have really good heat now from the heater.. engine runs fine.. must be more electrical..

any ideas anyone?

thanks in advance

Were they genuine parts or pattern ones?

Either one of those could have failed tbh, I used cheap ones and the thermostat lasted 2 weeks, the temp sensor a few months.

Both are parts that I would only ever get from a dealers now.
