2008 Hummer H3 QuestionsRefine by vehicle
dealer replace recall item harness & resistor. Drove 1 day then hummer overheated , returned to dealer replaced radiator, radiator cap, water pump replaced, thermostat replaced, checked over at GM dealership, Now the same thing happened again, any advice??? Why is the same thing happening?? Hummer overheated after 20 miles in outside temp 76 degrees. Only drove 3 days since work was completed.
Shouldn't this be a recall on GMS part as a safety issue? I have been told that a cracked manifold is a known issue with these 5 cylinder engines. Can it be welded? Would that be as expensive as a new replacement?
I smell coolant when this happens but no leaks. When the a/c off light goes away, everything goes back to working fine.
what does the ground look like.
The grinding started on the highway between 65-75 mph; loudest when hitting the gas pedal from a stop sign or stop light and between 5-15 mph. Now grinding when I start it up.
Thermostat + radiator changed ,antifreeze flushed and replaced, mech states bad guage any ideas what this may be I hear it's common in hummers? The guage stays half way while I drive goes up to 3/4 at idle never goes over never boils over, clutch fan does not have excessive play , please help this is getting expensive trying to fix.
