I noticed driving it today, the needle sits about mid way as usual, but sometimes when slowing down or idling it drops to about (if it were a clock face, mid way is about 1200) to about 1045 and jiggles between there and 1200, sometimes dipping to about 1000. It does not quit working, and it stays steady at 1200 most of the time. Thoughts on a fix or don't worry this is normal..\\? -- 93' 240 Classic Wagon 220K & 92' 740 Wagon Regina/Rex 90K Mark this post as an answer to my question<- Use this feature to mark quality replies to your post.

However, back in my '78 264 days, I had a radiator job done (self-diagnosed) when the problem turned out to be the voltage stabilizer on the back side of a "Rally Dash". Follow up on the electrics first, if it's an odd indication. Good luck. Garth Mark this post as an answer to my question<- Use this feature to mark quality replies to your post.

In fact, it barely gets warm on a cooler day, but always makes it to temperature in traffic, but drops down some when get on the highway. I ordered a thermostat and the sensor because earlier this year the on board computer said the ECT was bad, so you may have solved yours already - if you did, please let us know what the problem was. As a side note, does anyone know if someone squeezes the upper radiator hose to the thermostat, could it make the temp. gauge do this by putting either air in the system or something. I don't really know, but I remember someone did that when we were just taking look under the hood, I could have nearly hit them b/c I don't like people squeeze, pulling, and pushing on things under the hood with almost 300k miles and a lot of original stuff. Afterward (the next time I drove the car), it has been operating like I describe since. 10 miles of 45mph-65mph driving to work and barely makes it to temperature. It's been in the 70-90s, barely 70 in the morning. -- 1990 740 GL 293.2k miles Mark this post as an answer to my question<- Use this feature to mark quality replies to your post.
