During some recent rain there was some brown stuff all over the car that I thought was just dirt but later my vehicle started running hot. That is when I found a small hose was busted and it was replace. Now there is another leak underneath and it is running very rough. I took it to a mechanic and now I have to replace the water pump. I have had to replace almost everything on this vehicle and something always breaks down.
I took my car to a Buick dealer three times for the overheating and they ended up putting in a new thermostat and still had problems now have coolant loss all over the driveway and have to take it back after over $550 for a thermostat I never needed in the first place
I have had numerous overheating problems and I have discovered that the water pump is leaking. It is not yet resolved.
