On a C5 or C7?

Thank you, good point, I will make sure to mention this as well if the issue still occurs. I am praying that it does not, not being able to drive my car hurts my feelings. Lol Thank you so much for your reply. :-)

If i were king the thermostat would be in the radiator hose, accessible with a screwdriver or small butter knife :-)

.. and the heater core would be in a panel you could just lift out of the dash ...

Hey guys. I just got my water pump replaced for the over heating issue today. FYI, the "thermostat" and the "water pump" is one in the same. They are replaced as one unit.

Sorry-mine happened on a C5, don't know how a C7 is set up. For all I know it has a viscous fan and two electric ones...

Hi,
Was this an expensive fix? Mine is sadly out of warranty range. ;-(

Airbag

Just for Clarification . The Water pump and thermostat are not " one in the same" They are completely different parts with different functions and different part numbers. I Think what is confusing you is that they are often changed together as they are such a PITA to get to and both deal with cooling.

They can be changed independantly . ( i had to change my stat as i had an infant failure on mine when i did my timing belt job, but i sure as hell didnt replace the water pump again ...

BTW did it fix your problem and were you able to identify which component failed ?

Usually it is quite expensive as you would do the timing belt at the same time. A dealer will allmost certainly take you to the cleaners. But some independants can be reasonable. Some let you even source your own parts, but if it were me i wouldn't. Let them source them and get warranty on the whole job. How many miles on your car ? and has it had a timing belt done ?

You guys need to move this discussion to the correct forum. This forum is for C5 body style cars. If your car is 2005 or newer, you are on the wrong forum.
