writing from Italy . typhoon 1993 .electrical problems after replacement of engine of my typhoon in 1993: before dismounting it was all right, now the water temperature indicator rises slightly and comes light on the engine problems after a few seconds. We changed all temperature sensors, thermostat, but nothing changes. the engine ,cold or hot goes in motion, but cold if you switch it off after 1 minute, switching on again if seems flooded. tester says that water temperature is very low. we no longer know what to do. Thanks if you can help me

Runs well when i first drive and after driving it for over 30 minutes or so when i come to a complete stop it shuts down. Also after the truck has been running for over an hour and i turn the truck off it will not start back up untill it cools off. Any ideas of what it could be ?

it started with my distribuator,so i would just turn it but know it turns on and off

How do I clean the throttle body?

I have a 1993 GMC Yukon. The rear hatch (upper window) will not open. The relay kicks on like it is unlatching, but when the switch is released the latch sounds like it is closing again. Where is the motor located for the latching mecanisim? Also is there a possibility that it is in the switch or one of the relays?
