malk 0 Posted December 21, 2009 Been neglecting the Corrado recently and need to get it back sorted. The water temp indicator seems to be playing up and I need to know what needs replacing. Is there a sensor that connects to the expansion tank or on the tank itself? I also think the heater matrix might be on its way out. Hot air from the heaters only comes out once in a blue moon but could that be to do with air in the system? I'm thinking I might just get it all done at once. I.e. replace all the sensors, the matrix and was thinking about swapping the expansion tank for a mk4 one but apparently that only works for VR6s. Any advice would be appreciated especially if a few part numbers could be thrown my way. The car is a 1990 1.8 16v. Cheers, Malc. Quote Share this post Link to post Share on other sites
