2 weeks ago my timing belt broke.
My mechanic suggested that I have the water pump replaced since they
would be in that area.
I agreed and when I got the car back the heat was not getting as hot.
I noticed that there was coolant leaking and took it back in. My
mechanic told me that there was a small leak in the radiator where
plastic met metal and it could not be fix...it needed to be replaced.
I knew about this and asked why it started leaking more after the new
water pump was installed. He said the new pump probably produced more
pressure and that caused the leak to leak more.
Ok, I agree to this and tell them to replace the thermostat as well.
I get the car back and still poor heat.
The poor heat was a problem after the water pump was replaced and
continued to be after the radiator and thermostat were replaced.
What could have changed after only replacing the water pump that would
have caused the heat to be poor...it worked fine before getting a new
Note: The heater core was replace in this vehicle a little over a year
I don;t necessarily want to take it back to this guy again because this
thing just seems to be cascading. What I'm trying to understand is why
the heat went bad after the water pump was replaced.
