Contour Enthusiasts Group Archives Forums General Troubleshooting prestone leek

ok something weird happen yesterday, i was driving and the water coolant warning light up (that happend sometime) i stop at a shop for 15min and when i came back there was this HUGE spot of prestone on the ground and the tank was really lower (i check and there was a lot of prestone over the tranny)

i put back water in until max and drove home stopping along the way to check, it been almost 2 day and the cooland didnt leak again and didnt move from the max line.

So im wondering how come its suddendly leak and now it seem perfect ?!?

Check for coolant leaks above the trans. Make sure you don't have any cracks etc.

i checked n didnt see any hose leaking and it really weird, while reading some older post i begin to be afraid about the head gasket...

You're not going to have coolant spilling on the outer surfaces of the engine if it's a headgasket issue. You'd also have have issues of the engine missing and hot temperatures.

I would suggest that you have your filler cap pressure checked. A weak cap can cause a problem as you discribe. My daughter had a similar issue. AF would leak on occassion. New cap was the answer.
Generally you can track the coolant leak to the point of origin. The coolant will leave a film on parts that do not heat up.
