Hi !

While you�re still at it, check two coolant pipes if you haven�t !
One big that runs from the waterpump , tucked in between the exhaustpipes on the left hand side,to a hole in the "firewall" where it�s connected to a hose.
The other is a thin pipe between the waterpump and the oilcooler .
The big pipe is visible from underneath the car, if there are "bubbles" on it, try scraping them with a knife tho make sure it�s not rusted.

Cheers
