My car is losing coolent and there is no visable leak It has to be a coolent seal I dont see what else it could be. I check the fluid top it off and drive maybe ten miles and then i get te buzzer but sometimes it goes off and when i check the coolent its full I dont know what to do I just moved and dont have money for a rebuild or a new car does anyone have any Ideas I need help bad I think its giving me an panic attack

well maybe you should check and see if your sensor is working properly per fsm. also have you checke behind the water pump. i know that i had a coolant leak and i couldn't find it but then i took a look right underneath the omp and then i saw some coolant. i would try that out.

Or it could be that you havent got all the air out of the system. There is a write up on the proper way to do it in the FAQ or archived forums. cant remember which.

Check that the coolant overflow hose is hooked up correctly. If it's hooked to the wrong nipple on the overflow tank, it can spill into the tank but cannot be drawn back in.

Heater cores seem to develop leaks as well.

Mine leaks somewhere under the intake manifold.

I vote for checking the water pump first also...if it's still in the "seeping" stage, the leak is hard to spot...

Check the coolant level sensor. Mine was drinking all of the coolant out of the overflow battle, and it turned out that it was spraying out of a crack in the sensor at just under 13psi. Hard to tell at idle.

Once the buzzer starts going off, smell your engine bay for coolent (sweet smell). There may not be much of a leak but a crack or small tear in a line can cause the coolent to lose quite a bit of pressure and not stay at optimal coolent temp.

I have to agree with that!
I was looking for my leak for a long time, turned out it was coming from the small pin hole thing on the bottom of the waterpump.

I just got back from a ride it is putting coolent in to the over flow but not taking it back in the hose on the over flow bottle goes to the theromstat housing but there is a place to put it on the radatior that is cover with a vacum cap and hose clamp so where should i start to find and fix the problem now

if your engine is sucking coolant, you should be blowing smoke. also, try running it without the radiator cap on and see if coolant comes flying out. search around for blown coolant seals and you'll find more info on this test.

is coolant black light reactive? if it is that might work...

CompuBob

man, go to yoru car right now and look under your waterpump, I'm willing to bet you will see a white streak of coolant under it.
