should the thermostat be the first thing i check with this?? it cools down when i hit 80 on the highway.

 

Make sure your electric fans are coming on! Those NEED to be on when the car starts to get hot. If they don't come on, check all of the wiring and relays. Check to see if your car has an air dam underneath the engine bay also. It's a black piece of plastic that directs air up against your radiator. DEFINATELY, check to see if your water pump is working first, and then your thermostat. Once the engine is up to temperature while idling, try to squeeze the upper radiator hose. If you can feel the water pressure inside, the pump SHOULD be ok. Do a search in this forum also for other ideas. goodluck man!

also..get a bottle of Redline Water Wetter and add it to your radiator coolant.

Other than that,

First try and see if there are any leaves stuck in between your rad and condencer.Then replace your thermostat with a 160 thermostat.Also try setting up a manual fan switch so you can turn them fans on when you want to.
