Hi

Today, when I switch the a/c on it work but not very cool the outside temp was 47°C (116.6°F) after 15 min it cool but not very cool. The engine temp gauge reach after middle by quart . Then when I reach my destination I switch A/C off but when I turn it off the rpm goes down and oil gauge stop on red line and car shutoff also.

Anyone know what is the problem?


thank you

 

What year is your truck?

Two things to check:

make sure your your throttle body and butterfly valve are clean

check the function of the IAC

The year of my truck is 2000 the throttle body already clean. I always clean it , but how can I check the IAC and where is the butterfly valve located ?
