Hey folks, wonder if anyone can help with an issue just started getting with the car?? I'v read through some of the previous posts on the z18 engine but still cant see anything explaining whats goin on??
Basically my coolant warning light is on (bottle full) temp can go as far as halfway (on short runs, on long motorway runs temp can be fine??) then the fan kicks in n stays onfor remainder of journey??
I'v replaced the thermostat and there is no differnce, could it be the temp/fan switch, is the ecu being fooled somewhere along the line, could there be a blockage in the radiator or something (although getting heat through the vents)??
Its got me stumped and would very much appreciate any help n advice anyone can give me??
