Intrigue Temperature Problems

[Rob Mercer]

Ok the "HOT TEMP" dash light was lit and the gauge was in the red zone! But was the engine boiling over and filling the boil over tank? Do you think your engine was HOT?

If was going to guess I would say CTS sensor. This sensor can be tested with a ohm meter in the car. Do the test while eng is cold and hot see what the difference is. You are not alone with this problem, sence your car is a newer one you might try autozone for a free scan, the scan will inform you of temp output of CTS, compare that with what dash guage pointer.

Airlocked. They didn't burp the engine properly, there is a bleed valve on the upper right corner of rad open it halfway then start engine and observe the air bubbles evacuating the rad, once stream of coolant only is observed close this bleeder valve. If over heat still exists then run car to operating temp, use caution to remove the rad cap/recovery tank cap idle up to 2000rpm for about 10 mins and observe the air bubbles evacuating the recovery tank, one the fans kick on the thermostat has opened and you can reinstall the cap, do not shut engine off while cap is off as this will create another airlock, (learned from experience) This should end your overheat problem. If engine was not burped/bled correctly of air the thermostat will not open.

Also use the correct thermostat, I'm in Canada the AC delco are discontinued but Gates has one it OE the part number is 33953 at Lordco. The car runs like new now.
