So mom's 98 Malibu (4cyl 2.4L) leaks coolant but weirdly. 1st of all, I do find coolant on the floor under the car but cannot find where its coming from. The reservoir's level keeps dropping down, I'll fill it up and 10days later its low again. I took the car to 3 different professional mechanic shops and they did a pressure test but during the pressure test mysteriously not a single drop of coolant leaked. However, every now and then i'll find coolant on the ground and reservoir's levels dropped. One of the mechanics suggested I change the reservoir's cap, I did that and still the coolant keeps leaking and still no signs to where the leak is coming from.
The engine has not overheated yet nor showed the signs of any problems.
So, what do u think could be going on, and how do i solve that.
thanks for readingWhat is happening to the coolant (98chev malibu)?The only way an engine loses coolant is by a leaking hose, a leaking water pump, hole in the radiator, a leaking head gasket, (which will cause performance problems), or a leaking freeze plug. Try to determine where you see the leak on the ground and look up in the engine while the car is still parked above the leak. See if it is leaking from the front or rear of engine. This will help you narrow down some of the components i just told you about. A crack in the intake manifold is another area of leaks , but this is very rare.
good luck...What is happening to the coolant (98chev malibu)?the design of the upper intake gasket on that car is defective. it will keep leaking until you have it replaced. (cost me $400 to get mine done) if you decide to keep the car, you will have to get it replaced again because gm didn't fix the problem.What is happening to the coolant (98chev malibu)?it may be a head gasket. i can't believe 3 mechanics can't find the problem. what they need to do is drain the coolant system and pressurize it with air or put a dye in the coolant and find it that wayWhat is happening to the coolant (98chev malibu)?lets hope it,s not what i,am thinking. i,am thinking it might be a hole in the transmission cooler on the radiator and the coolant is mixing with the transmission fluid.i don,t know if that,s what it is but it would,nt hurt to mention it to the mechanic.
