while driving yesterday a light come on for the low fluid and the temp gauge started to rise fast. I pulled in to a parking lot and saw my coolant was leaking all over the place. I refilled it and drove it home which wasn't far. Did some research online and found out it could be the water pump because it was so much fluid. So we replaced the water pump and the coolant is still leaking out as far as I can put it in it seems from the front center of the vehicle. We are 4 days past our due date for our baby to be born so I need to get it up and running stat. Any help you can give me would be great.
There is no substitute for having the cooling system inspected, either by yourself or a mechanic, especially when a problem like this is so easy to trace (follow the leakage to its source). As you can attest to, throwing parts on without verifying if they really needed to be replaced can prove to be quite expensive.
That said, here are some possible reasons for significant loss of coolant:
compromised coolant hoses
In my experience, even a small cut in a coolant hose (especially the one on the high-pressure side) can lead to significant coolant loss over a short period of time. If this is the case
a gash in the radiator
Probably due to road debris. The usual fix is to replace the radiator.
loose hose connection
If a hose clamp has failed or was improperly tightened, pressurized coolant will find its way out. Replace/tighten as applicable.
The integrity of the cooling system is vital to the operation of your engine. Failure to ensure can cost a lot more in terms of engine damage and/or repairs.
Too many of these threads don't mention a possible leak at the intake manifold gasket. If the leak is not obviously coming from the water pump/gasket, perform a leakdown pressure test and don't forget to check. Those end seals sometimes don't get sealed correctly and they can break down over time due to heat and coolant contamination.
