I loose a lot of cooling fluid when car is parked all the sudden a big amount of cooling fluid come shooting out on the front driver side my mechanic has no idea what it can be so I hope to find some answers myself don't want to ruin something else in the car
Engine is overheating and coolant is just spewing out all over the engine. Also, now as I pour water into the radiator, it just flows right back out somewhere else. guessing the water pump.
Keeps losing coolant no visible signs of a leak until today noticed coolant leaking in center of engine
Coolant leaks that cause engine to over-heat and steam to come out under hood, on passenger side.
coolant leaking and engine overheating. trying to find a diagram of the engine before we fix it.
Developed coolant leak which progressed into discharge of coolant into engine compartment. This break caused lack of pressure in coolant system, with water pump no longer circulating coolant to engine. Discovered broken hard plastic elbow leading from engine block to water pump.
Coolant is leaking out of the water pump and engine is overheating. Engine has been using 1 qt of oil for every three fill -ups.
havent fixed it yet, but my car started making weird noises so I took it in and it's the water pump leaking onto the belt.
Something very similar was happening to me. Just driving last summer when my low coolant light came on. Could not figure out why until I had it confirmed I had a bad water pump leak. Simple fix was to replace the water pump (cost me 35$ for the part). But watch out, the coolant that was leaking started to mess up the serpentine belt and I had to get that replaced as well otherwise it completely destroy it.
Leak began in summer of 2012 Las Vegas NV
Found problem and replaced both radiator hoses, replaced thermostat and water pump.
The engine used to always run under half on the gauge, however due to the leak and changes it runs between half and 3/4. It does just fine until summer hits and between june-September the engine will over heat if running in town for even 10.minutes, does OK on freeway but once it slows and gets no air she's in the red.
coolant leakage under engine on the passenger side of the car. I was told that it could be a plastic intake. Please let me know if this could be the problem.
