Recently bought a Gsi turbo that blew the original engine so replacement it with another z20let and has been going good so far but recently the coolant/fan light came on but didnt cause any problems and was still holding the temp fine.... Untill today... now the fan wont come on atall!!!!
Got a few codes coming up.. None of I have ever heard of.
P0530 - Airco Pressure Sensor Voltage High
P1490 - Hot Soak Pump Relay Shorted To Ground
Any ideas as cant really drive the car way it is and need it....
