After driving for about 10-15 minutes on cold (Less than 32 degrees), days, my heat gauge goes very high for a few seconds and then back to normal. It doesn't do this again unless the engine gets cold again. When this happens, the overflow tank also overflows about a quart of water. I figure it is the thermostat, but I know very little.

It just started messing up and replacing power steering pump l seen a post some models or all were recalled and replacement was free. Please tell me if that is the case

The vehicle has 170k miles. Runs great and smooth when going down the road but when its in park or in gear idling it sounds like it has a big miss. (pu pu pu pu pu pu). And sometimes when coming to a stop it will go dead. And I was going up the highway the other day and the battery light came on and stayed on for a few minutes and then it went back off. Recently had new plugs and wires installed and a new fuel filter.

the van sat all winter

Trying to replace
the tubeline, is there a certain way to take out? It is leaking.

V6 3.8. Sorry i recently posted the wrong code

Where will the problem be. We have cleaned the EGR valve .

I put a used transmission in the old one had no forward. Everything was working fine until I took it on the freeway. At about 60mph the O/D light started flashing I could feel the overdrive coming on and off. RPM went from 2000 to 2300. When I turn the engine off and started again light was off drove fine until I went on the freeway again. The used tran. was out of a 2000 Windstar 3.0L. The only difference was the shifter connector and had to use the 3.8L tran. TSS sensor because the wirer connector is different from the 3.0L. I don't want to do this job again but if I have to I will. What can I try before I change it out again.
