I just replaced the water pump and thermostat, while doing a full flush and replacement of DexCool. The problem is that the engine runs at a steady 210 now. All air is out of the system, and it is completely full. The gauge does not jump or do anything funny. I'm thinking AutoZone gave me the wrong thermostat. I used # 467-195. Can someone tell me if this is correct, please?

Sorry, just finished searching, and found out this is a valid #. If full flow for this 'stat is 195, then why is my temperature at 210? Perhaps I should try the 180 or 170 degree thermostat?

 

A stock thermostat is a 180º not a 195º. A car will normally run close to 10º over the thermostat opening limit. Get a 180º thermostat and make sure it is the long design for the reverse flow system.

 

Thank you ever-knowledgeable Shoebox! I'll make sure its 180 and long design!
