Engine Cooling problem
1994 Chrysler Van Engine Size unknown Wheel Drive Type unknown Automatic 163313 miles

It happened 2 days ago. The temperature guage would go past the normal operational range and it will fluctuate. It would go all the way to "H" and then it would go back down to half way mark (which is still past normal operational range). This fluctuates a lot and I can't seem to find the problem. Because of this, the radiator fan is working extra hard and I usually don't hear it at all while driving but I hear it on all the time now. The "Check Gages" light also comes on, but I'm suspecting this is due to the temperature of the engine coolant going up to the "H" mark. From reading the car manual, I do suspect that there may not be enough or any pressure in the cooling system to move the coolant along. There is no leak from what I can see. I had the radiator flushed at Mr. Lube in January. I'm not sure if the problem originated from there although this only started happening 2 days ago. Any advice?

Try replacing the thermostat-not it do the following below:

Have it block and pressure tested-do the block first to pinpoint a combustion leaking into the cooling system or a gas analyzer to sniff for hydrocarbons at the radiator fill neck.

Pressure test: do not do a pressure test if there's leakage at the headgasket this might cause coolant into the cylinders and lock it up or bend a connecting rod if cranked thereafter. The headgasket should be repaired before doing the pressure test.

If the block and pressure test passes check the following: Thermostat, Pressure test the Rad. Cap, Clogged radiator, Fan clutch, Radiator electrical fan, collaspe hoses, water pump.

Ah, thanks for the quick reply. I am not car technical savvy at all. So I personally can't do any of what you just advise me to. But I will definitely take that advice to the dealership so that I can avoid any costly repairs that they may try to gimmick me into. Thanks a bunch!
