I have a 2002 Saturn S-Series. The low temp light comes on and every three days I have to refill the reservoir, which after so long of doing this I start filling it with water.
I just put a new thermostat and reservoir on it and it runs good but when I stop at a light for a period of time or at the drive thru it tends to boil over. Help me please. And thank ahead of time.
You may have a leak in your radiator, and ensure that your reservoir is not filled completely. There is a FULL line indicator which typically is no more than 2/3 up the jug which may be why it "boils over" for you. I recommend having a mechanic perform a coolant pressure check to locate the exact point of fluid leak.
Something is wrong with your Saturn that it keeps needing more coolant and it keeps boiling over.
If you keep driving it like this you could damage the engine.
I recommend you tow it to your regular repair shop and have it diagnosed and fixed ASAP!

Seems you have had some work done on this. But whoever is doing the work has not gotten to the root of the problem. I believe you have a coolant leak somewhere in the system. Could be hose or radiator. Have a trusted shop find the cause of the coolant loss.

Sounds like you may have a leak. Have the cooling system pressure tested. If it's not a visible leak, there may be something wrong with the water pump & you'll have to do the thermostat again since it's overheating.
