| Message | removing my water pump tomorrow. need a tool to remove the under drive pulley, so that delayed the progress.
 :But, its a new OEM thermostat and I drove it for only 500 miles.
 :Tested the thermostat and it opens fine, to 14mm.
 :After that, I've observed that the heater is lukewarm, does that mean the heat valve has a problem?   If it does, will it be the cause of the overheating in the first place?
