i just had my water pump done to fix a persistent coolent leak. Prior to the job, and afterward, the Check coolant message on the diagnostic pops up.
The car doesnt heat up,......the leak is fixed, and it is filled with Dex coolant. That said, is there a way to reset it so the lite doesnt come on? Info reset buton?
curious,
gwrote
The radiator may be filled but does the overflow tank also have the proper level of coolant in it? It is not uncommon for trapped air to bleed out into the overflow, making it necessary to add to it a couple of times after a radiator job. Since that is the first place that the level (normally) gets low, I suspect the sensor is in the overflow tank.
AFAIK that indicator is not resettable.......except by getting the coolant level (in the overflow tank) up to where it should be.
Failing that, ask the person who replaced the pump. ;-)
Ok,..so how do i get a peek into the Radiator? If i take off the vinyl cover it has over the radiator/battery and such,..will i be able to see it? Thanks in advance for all responders,...... i ll also try and do some research on line.

Ken is 100% correct.
You have to check the pressurized "Surge Tank". On a cold system, twist off the cap (which is just like a radiator cap), and with a flashlight, check the coolant level. It should be about 1.5" below the filler neck.
If the coolant level is just about right and you still have the warning on the DIC, the sensor is likely shot or its electrical connector is broken, loose or corroded. It's down at the front bottom of the tank. If the sensor has gone south, you'll have to replace the Surge Tank (it comes with the sensor).

You don't. I did not say to check the level in the radiator. You need to check the overflow/expansion bottle.........as described in another message here.
If you can't figure out what/where the expansion bottle is, take it to someone who knows what they are doing !!!!!!
Ok, i misunderstood your statement. The surge is at the proper level.

Mine Northstar at 140K has a cylinder head coolent leak. If you start loosing coolent even though there is know leaks in hoses or radiator system that is what is happening. I know this because I have been fighting this battle for a year know and finally figured it out. It starts out with rough starting idle and then clears up quickly (water in cylinder). I finally figured it our one morning after seeing my mon start the car and white water vapor (more than std catillitic converter moisture) spewing out the exhaust. Went down to the auto store and purchased "Stop leak" and followed the directions and pured the stuff in the radiator filling system and the problem went away. I've been driving it for about 5k miles and its still OK but I know the head gaskets need replacing.
Note that I did have a radiator leak prior to this and thought that was my problem (Cracked plastic side) but like youstill kept loosing water. I also repalce all the hoses. Some hoses are a pain to replace. After I knew it was not a hose I came to the above conclusion!
Bella is correct. I had the same problem on my Northstar Cadillac. The sensor in the plastic tank gets a coating of slime from the Dex Coolant and there is no way to get to it to clean it. The only solution is to replace the tank. Fortunately it is neither difficult nor expensive.
