I have a 1995 buick skylark. Recently my temp gauge constantly goes up and down. It will go up, stay up for a minute then will go down. When it goes up the heater goes cold, then when it goes down the heater is warm. A few times my temp gauge has come on and have had to park for a few minutes for the temp to go down. It is like a switch. It instantaniously goes down. I have replaced the thermostat twice and the problem is still there. In the past 3 years I have replace the radiator, heater core, and water pump. Can you help me. Someone suggested the fan is out.
have the same problem?
