My 2000 GAGT has the same issue right now..coolant light on ... but coolant level is fine.. temp gauge is fluctuating a bit.. what should I do.. car is still driving fine..Would a thermostat cause these problems ??

The level sensor in the bottle is bad.

As for your temp gauge fluctuating more than it should, could be the coolant temperature switch. Is the SES light on?

Tap the sensor with a screw driver

not really bad, could just be an air bubble on top of it.

Mine has the exact same symptoms but the coolant doesnt dissappear in 2 days.. it seems like a slow gradual leak somewhere but can't find where. At times I may see a few drips on the driveway but it's not always consistent. I have been leaving a jug of coolant in the trunk for quick top ups. The water pump looks fine, the area is completely dry and the lim looks great as well. Checked the oil, even an early oil change to take a look.. oil looks great.

You may have to start looking at the piping and possible connections going to the rad, if not the rad itself. If it was the rad though, then you'd def see it burning off.

I think it's burning off somehow in the engine.

Funny thing is.. now I have started going back through the repairs and stuff I've had on the car.. I bought the car new in 1999/2000.

In 2003 while the car was still under warranty at 75,000km there was a repair for a leaking/ruptured lower intake gasket. Coolant flush and the works.

And again in 2005 at 125,000km the same repair again. So that's 50,000km later.

And wouldn't you know it .. guess what the mileage is again... yup you got it another 50,000km.. She's sitting just under 179,000km now and the coolant is leaking again.

Sounds like you need the shop to stop using the crappy plastic gaskets. You do realize they made revised metal ones, right? I changed my LIM gasket back in 2008 and over 70,000 miles ago, no gasket leaks.

If this indeed the problem again.. after I see my mechanic this week
I will be buying the Fel-Pro gaskets at Canadian Tire.

The fix is still cheaper than a new car tho..
Even tho it's a pain in the a$$ and sucking my hard earned money.

another possible coolant loss is bad head gasket pressurizing the coolant while driving and forcing it out the overflow.

that may not be the op's problem but for anyone looking for a leak check if the coolant hose is under excessive pressure after a short drive.

That is very true. I've only had the lim gasket changed once using the new material gasket and over 140 000km later, it's still good.
