Ok where do i start since owning my mk2 great car but nothing but water problems.
Ok to start with its had a new thermerstat.
now since yesterday the car was blowing cold in from heater thought nothing of it then started to play with a wrx and as soon as i put my foot down in third gear the oil temp went right up and so did the temp gauge, i pulled over and water was pouring out of expansion bottle.
About an 5 hours later topped up water still cold air out of heaters but engine temp and oil temp fine did not rev it over 2k.
Also checked that there is no oil in water and vice versa.
So the help i need after doing a search on here.
Do i change water pump,
Do the bypass thing to heater matrix
Buy a new bottle cap
Or is there something else wrong
cheers in advance
