[QUOTE="Anybodyhome, post: 456325, member: 19161"] The coolant temp at 154 is low. This would lead me to believe the t-stat is stuck open and the engine is not getting to operating temp while coolant is flowing. Easiest check in the world: let the engine cool and have someone start your vehicle cold while you wrap your hand around the upper radiator hose. If you feel coolant flow through the upper hose as soon as the engine starts, your t-stat is stuck open. Had this issue a couple years ago and replaced in an hour or so after ordering from [URL='http://partsgeek.com']partsgeek.com[/URL]. [/QUOTE]
