overheating, coolant loss
Leaking coolant from under water pump
water pump failure at weeping hole. Flushed system and change coolant/thermostat/radiator/ecs sensor/relays still runs warm bleed coolant system too. intermittent low speed fan failure guessing broken wire or pcm .
The other day driving home from work a low coolant light came on the car as i was driving. Once i got home there was coolant all over the right side of the engine. The engine did not over heat and still starts and runs good. I was thinking it was a blown head gasket at first but i knew it wasn't once i checked my oil to see it was full and not mixed with coolant. (thank god) the only thing it could be since the resivor isn't cracked is the water pump. Which i will be replacing in he next couple days. (no im no driving the car)
