    Are you sure the problem is the water pump? How do you know? Overheating can be caused by more than just that.

Does anybody have a video link on how to flush the cooling system on a GM 3.1L SFI OHV 6cyl motor? I need a vid for this particular motor cause mine is still overheating & i have looked everywhere.

flushing a cooling system is the same method as any other motor

do it without the thermostat fitted
or water pump opening

sacrifice an old radiator hose to adapt a garden hose fitting
for radiator flush

air in system fix
your thermostat housing has no air bleed valve
no top radiator cap

old school way
heater on full
run motor till thermostats fully open
burp radiator hoses
wait till water is running up into over flow bottle without bubble
replace cap
turn off heater
correct level in over flow bottle

why still over heating
you fitted everything i would have ... yet still overheat
leaking inlet manifold gaskets
hose clamps loose
cooling fans spinning too slow
thermostatic fan switch faulty
aluminum radiator is a big one
air ..fins bent or some water channels blocked

or possible head gasket leak

Overheating Ford 7.6 liter Diesel Engine

A water pump is like a piece of jigsaw that will fit only one way around. I did once hear of an impeller that fell off the shaft but once in 40 years is pretty rare. Mostly if the bearing is ok and the seal doesn't leak they are fine and if the coolant circulates the pump function is also fine.

My first question is to ask how sure you are of the mechanic's competency and honesty given his comment about the water pump? Unless there is a faulty climate control or similar, heater function is usually fairly consistent unless there is something floating around in the cooling system causing a blockage - or combustion gas is leaking into the cooling system where it can build up and commonly disrupt the thermostat operation and often also the heater, the former causing overheating and the latter inconsistent heater function.

Some gas is normal even with a healthy engine and manufacturers usually design in a degassing route so the few bubbles can quickly and harmlessly escape into the space above the coolant level so if the route becomes blocked or the amount of gas is excessive trouble will follow.

A few other possibilities are:

Insufficient air flow through the radiator core.
Insufficient coolant circulation through the radiator.
Insufficient coolant circulation through the cylinder block due to sediment.
Defective or incorrectly fitted thermostat.
A too-soft bottom hose being sucked flat due to a high water pump demand.

Good luck!

Leaking, overheating --- *fixed* then puff of white smoke 1 week later

I'm not taking sides in this. So what I am going to say is more or less neutral.
There is a big possibility you damaged the head gasket when the engine overheated last week. The dealership would have no way of knowing this if it was not yet leaking into the engine when they replaced the water pump.
Once the water pump leak was fixed, the system would be running under normal pressure which could finish off the weak head gasket.
You can not see a damaged head gasket without removing the cylinder head. And you have two heads with two gaskets.
So, IF the head gasket is now blown there is a good chance they did not know it last week. It could also be a cracked cyl head or leaking intake manifold gasket. Or all of the above.

Ford expedition fix

it was the water pump. they replaced the water pump and now it runs ok... but from what i hear it could only be 4 things... thermostat, water pump, or head gasket, or your car may not really be over heating and has a bad sensor...this is a problem where it will be easy for a mechanic to take advantage of a customer. they claim it was the water pump but i think it was the sensor. they charged me $360. i felt like i got robbed because the pump only cost like $60 and i had someone who would have done it for $80. now im having problems with my assing gear. i cannot floor this thing for nothing but it picks up when i let off of the gas.
