[QUOTE="Anybodyhome, post: 437833, member: 19161"] Couple thoughts as I recently replaced my thermostat: 1. After install the temp was steady and in a good place. However, the temp gauge was spiking up and down intermittently. Let it cool, took the radiator cap off and topped off with coolant there instead of the reservoir. Was perfect afterwards. Pockets of air in the system will cause temp fluctuations. If you fill via the radiator, it forces the air back out the cap, so you'll put some coolant down the funnel, it'll settle and you'll get a burp, continue until the coolant is at the top and no more burping. 2. If you have JScan, you can change the temp the cooling fan comes on. Maybe adjust it 5 degrees lower? [/QUOTE]
