If it is a small sensor like I'm thinking, then it should be just to the right (driver's side) of the valve cover sticking straight up with a wire w/ female end connected to it.

If temp needle is jumping, I would suspect air in the cooling system. Did you install the thermostat correctly and removed all air from the system?

They must have changed location on 98's. My needle jumped around prior to and then I changed it and it was fine, so Kokujin yours must not have been working correctly.

Sidenote - all they did was take out the old and put in the new, so air has nothing to do with it.

re: needle jumping - trying reseating (remove, clean (w/wire brush) & reinstall (with loctite or RTV) the temperature sensor in the rear water block of the head - slightly to the front and below of the engine lifting hook.

You're talking about the temp sensor -- not the thermostat ;)

I didn't understand CCStooge, until your post. I still have to find the first person changing the thermostat without air entering into their cooling system :smile:

I don't know about the 626, but my previous car had a very small hole on the top part of the thermostat to let air through. So when installing it, not only the spring had to be facing the engine, the hole had to be on the top: otherwise air would stay trapped in the system (took me quite a while to figure out why my temp needle was going crazy...)

That makes sense Trebuchet and sailor, sorry for the confusion.
