I'm trying to figure out why my engine seems to be running cold. If I drive to work (about 12 miles) and the outside temperature is at or below approx 32 deg the engine will stay around 108 deg. That is traveling at about an avgerage 45 mph. When I have to stop at a street light it can warm up to about 117 deg. Now on the other hand when I drive home and the outside temperature is above 40 deg it will run in the 160 to 180 deg range. When the engine temperature stays around the 140 to 150 deg mark or higher the auto climate control will work and heat the inside of the cabin. When it stays cooler than that I can't get it to blow hot air to heat the cabin. I recently had the engine replaced with another used engine. It also has many new parts (probably unrelated). The starter, intake mainifold, thermostat, plugs, wires, gaskets, MAF sensor, belt tensioner, engine coolant level sensor, and water pump just to name a few. What are some things that would cause it to run cold under these conditions?
have the same problem?
