Temp guage Rises/almost oveheats when Heater is on. Temp Rises to almost H then drops fast to just above C and repeats but only while heater is on


The cooling system has an air pocket in it. The best solution is to have someone with a vacuum coolant system,and drain and replace the coolant. The only other way,is to jack up the front of the vehicle,and take off the radiator cap,and run it with the heater on full blast. Wait till the thermostat opens,(when coolant level drops)...then top it off while its still running.If you buy ,or have a friend who has a tool called an "Air Lift",..it will make this MUCH easier,and cleaner to fix.

97 Subaru Legacy, 142,000 miles. Temp Guage


Sounds like the Coolant is not full and has a air bubble. It is very important to have the system filled complete. That would be the first step.Good luck and have a great day.

02 grand prix temp rises over 210 then drops back down. heater


dear friend-there is a couple of things you can do to find the problem,when the engine is cold remove the radiator cap start the engine then look inside to see if the water is circulating,all so look for bubbles in the water,if there is bubbles,you might have a blown head gasket,if there is circulation the water pump is ok,then get the engine up to working temp,then feel both the top and bottom radiator they should be the same temp,if not then the termostat is at fault

Chevy Venture Overheating


Almost sounds like the same symptons as my van. Turns out the guage was not the problem. The van was in fact running hot because the electric radiator fans were not kicking in when the engine was hot. I replaced the relay switches for the fans. There are two of these in the fuse panel under the hood. There has been no problem with overheating since

You may have an air pocket in your system which some times happens.  One way to get rid of it is to take the upper hose off on the engine side,  fill your system with water until it runs out from your engine block, replace the hose, start your car turn you heater on and set to hi keep the radiator cap loose until the temp start to rise then close tight.  Once the air pocket had been remover you can drain some of the water from the radiator using the lower drain plug and add antifreeze.

Intermitant temperature


Check to make sure your thermostat works right by monitoring the warming up of your engine. With a completely cold engine, start and run the engine for a few minutes, then put your hand on the top radiator hose to monitor if and when it gets warm as the thermostat opens more and more and note the gauge reading( if it works) the top radiator hose should be unbearably hot within 5-8 minutes. If the therm. opens right it should close right aswell, staying open a little while eventhough the radiator may have cooled may be what you are experiencing causing the rapid cooling and is nothing to worry about. The Hose should not get warm very soon after starting the engine. Regarding you gauge, lets take one step at a time, verify proper op. or the therm.
