Bought this two months ago from a kid that rebuilt it... so far we found tha:
. He replaced the '02 12V engine with an '03 24v engine
. We replaced water pump and crack pipe
. if engine sits idling for 20 minutes it overheats.. lights come, etc.

Any suggestions?

thermostat or water pump.

Ok, since I mentioned above we replaced the water pump.

but it could be the fans are not running

you also have a temp sensor that initiates your radiator fans. If your fans arent coming on then it may likely be the cuplret..although 20 minutes is a long time for the engine to run before the engine overheating if its the rad fans.. It only took my car a few minutes standing still.

Thermostat is common as well.
