Ok...! My 1997 CL 3.0 spiked a temperture yesterday while sitting in Tampa, FL traffic. This happend once since I got the head/ gasket work done. The mechanic says it is the water pump (blades) because when I get up speed/rpm the temp gauge goes down, but; only to mid-range (normally she stays a lil under mid). Can someone PLEASE PLEASE PLEASE give me some input????

 

water pump.

and did your car over heat in the first place? is that why you got head/gasket work done?

 

@ justnspace - THANKS FOR THE REPLY! Yes, she overheated after I purchased her used and was trying to drive her home. I got the head gasket replaced, head machined, new thermostat & switch.

 

be careful!!!
it will happen again! all that money and time you put in to re-machine the heads will go down the drain if you dont correct the issue.

water pumps go bad.
replace the water pump!

 

The thermostats are notorious for going bad

 

justnspace- thanks for the info. I ended up replacing thermo, coolant fan switch sensor and the water pump. gauge still goes above half and the fans kick on and brings it down to halfway mark. I will flush the radiator this weekend.

 

ouch. sorry to see replacing parts hasnt solved the issue.

does the coolant look rusty? lol

 

Bleed all the air out of the coolant system. I am assuming the bleed valve is near the thermostat, on my F22B1 its under the distributor. I know the symptoms of a blown headgasket, I had a 92 Legend that had that problem. I think you're issue can be improved with the maintenance. Good luck.
