SOURCE: Replace 2005 Cadillac CTS water pump

drain the coolant.remove belt by rotating belt tensioner cllockwise. water pump pulley will require a holding tool to keep it from turning while removing bolts. access to air ratchet can sometimes eliminate the need to hold but be careful cause thats a good way to skin some knuckles. also make installation more difficult to obtain proper torque. after pulley is off just a few water pupm mounting bolts remain. clean and dry gasket surface very well before reinstalling.

How do i replace water pump on a 2003 cadillac cts n hw do i knw if its no good


Removing the timing chain cover to gain access to the water pump is a tedious job. Consider ruling out other causes such as a defechive coolant sensing unit which is relatively commom. Can you leave your hand on the radiator cap or is too hot?

Should the engine be running when adding coolant to my 2003 cadillac cts


If you just drained it & are refilling,then yes,the engine
should run & warm up until the thermostat opens & you
keep adding.

If it isn't hot & circulating thru the entire system, you won't
get it close to full with the rad cap off

2003 Cadillac CTS at 225,000 miles Code P0128 comes up periodically. Any solution other than a thermostat change at $400 plus?


First off who ever said $400 to change a thermostat is trying to rip you off. The actual part is like $20 bucks max and its so easy to change. I can guide you through it if you would like.

The P0128 code is Coolant Thermostat Malfunction.

These are the possible causes for this code:
- Insufficient warm up time.
- Low engine coolant level.
- Leaking or stuck open thermostat.
- Malfunctioning engine coolant temperature sensor.

These are the possible quick fixes:
- Top OFF Engine Coolant
- Replaced Thermostat

Hi I own a 2003 Cadillac CTS I am getting a check engine light error light with code P0128 and my heat is fluxuating up and down I have already installed a themostat. What are my options


A code P0128 may mean that one or more of the following has happened:

1-Low engine coolant level
2-Leaking or stuck open thermostat
3-Faulty cooling fan (running too much)
4-Faulty coolant temperature (ECT) sensor
5-Faulty intake air temperature (IAT) sensor

Check coolant level
Check to make sure thermostat is functioning properly Check the Cooling fan Check the ECT sensor Check the IAT sensor If all else fails replace the thermostat
