If i remember right you can't actually (easily) get the rad cap off. look at the overflow tank, you will see a line on the tank which is the maximum level to fill it. when it is cool check and see where the level is. add antifreeze to this tank when the motor is cold to that level.

How do you reset the low coolant light on a 2005 cadillac cts


If your level sensor is anything like the Seville, there's a magnetic float in the reservoir and a reed switch snapped into a receptacle in the bottom of the reservoir. Either the float sticks in the up position (it only travels 5/8") due to sludge buildup or the reed switch/connector/wiring has failed.

Here's a picture of the bottom of a 2000+ Seville reservoir. You can just make out the green float above the 2-pin level sensor connector.

2005 cadillac cts base water pump replaced by unauthorized dealer. Now "check coolant light is coming on again" Any thoughts on this matter


If there is no indication of overheating, the check coolant light is probably triggered by a sensor indicating low coolant level. It's also possible that there is air trapped in the cooling system from when the water pump was replaced. Trapped air could cause the sensor to throw the trouble light. Bleed the air from the cooling system and see if the light goes out. You may have to clear the light after bleeding the system.

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

Car leaks coolant but does not overheat leaks alot of coolant 2004 cadillac cts


find out where the coolant is leaking from, a minor leak could become a major leak at the wrong time. check your hoses. how much coolant are you having to replace. If you don't see where the water is leaking from try warming the care up or looking for the leak after you car has been driven. Be very careful hot water can cause serious burns.

I have a Cadillac CTS 2004.. 3.6L V6 engine. I need to know if my car has a dipstick? And is it to check the level or just a hole to fill.


I too have the 2004 CTS.
Just today, my dealership checked my transmission fluid level because I have gear noise.

There is NO dipstick!

The car is put up on the hoist with motor running and transmission in neutral.
There is a fill / level check plug located on drivers side of transmission through which the level is checked.
