I recently replaced my radiator for the second time.The first one got a hole in it.Thank goodness my son remembered that I had gotten a lifetime warrenty with it,so the second one came free of charge.This last summer,I had some work done and the macanic said that the water pump was going bad,and would have to be replaced soon,but he couldn't say when.He did some work,replacing the valve cover gaskets and thermostat,along with some other things that I can't recall at the moment.Now my car is over heating again,(hence the raditor replacement,it was really bad-caked with mud and gunk).So myquestion is why is it over heating ? And blowing smoke through the heater vents inside the car ? Is this the water pump or something else like the head gasket,or what.And did the exisiting problem,cause the last new radiator to go bad ? Please help !!!! I can fix alot of things myself,and am fairly decent at trouble shooting,but I haven't run across this before.
Thank you.
Sincerly,

Hello !!

Looks to me like your heater core is gone..

check under the dashboard on the pass. side for wet carpet...

that`s where the heater core is and you`re loosing the water from your cooling system there and that`s why your truck its overheating.

check that and let us know ..

good Luck.

Sounds like youve got steam in the cab from a leaking heater core. Is it a sickly sweet smell like antifreeze? You're losing coolant through the heater core and over heating.

Grab your radiator fan and move the top back and forth (not spinning, but towards and away from the engine). Is it loose? Look at the bottom of the pump, is it leaking from the weep hole (bottom of the casting towards the shaft). Finally, with the motor cold, remove the radiator cap and start the motor. as it warms up you should coolant flowing in the tank.

NEVER REMOVE THE CAP WHEN HOT.

If pump shaft is tight, not leaking, and you have adequate flow, your pump is fine. :wink:
