1990 Buick Reatta Questions & Answers
I have a 07 Dodge
Make sure your battery cables are clean and tight. I had a tow in one day because I could not boost it. After the tow in they replaced my two battery cables and bingo no trouble after that.
Cooling system
If you're certain it IS NOT running hot, then it is the gauge itself. I am assuming the water pump is pumping, etc...There may be a sensor plugged into the radiator or the resevoir you can disconnect.
1990 buick reatta starting circuit problems
You could have a bad relay in the start circuit. The relay is there because of the security system. If someone tries to jump the car to steal it, the alarm will disconnect the relay and the car will not start. I believe it is in the relay box in front of the air cleaner

Temperature switch will not work
The unit in the dash with the buttons gets dirty. You can remove it from the dash, take it apart and clean the pads under the buttons and I have had 100% success fixing the problem

Check & inspect bulbs and sockets on the right side front and rear. Also check the bulb and socket you just replaced.

My reatta has an oil
well it sounds like you have a major problems here . If your coolant level is dropping and the oil level is high it sounds like you have a head gasket leaking coolant into your oil system . Is the oil a milky color . if so i would look at a head gasket problem . Also if the oil does look milky it may have gumed up the oil level sensor so it is not working right
