How hard is it to replace the thermostat on a 98 Voyager with the 3.0 liter Mitsubishi V6?
We've had some really cold weather on the east coast the past few days and I noticed that the temperature gauge in my wife's Vger is only going up 1/4 the way, even on the highway. In the summer, the temp gauge would head up about half way.
I'm thinking I have a defective thermostat, which also could explain the poor gas mileage the minivan has gotten for some time, asssuming it's not getting up to proper operating temperature. The vehicle also takes a long time to warm up - more so than it used to.
I haven't looked under the hood yet to see where the thermostat is located to see if this is a job I can do myself. If it's behind the timing belt cover, I may bite the bullet and pay to have someone do it, but if it's an easy job, I'd like the challenge.
