“My Suburban has had 4 radiator failures since new. All have been due to electralisis. Gmc paid for the 1st failure (part only I paid labor) even though the truck was over 10000 miles out of warenty. The 4 radiator has now failed and a 5th is required. Gmc is well aware of this problem but insists thiers nothing wrong with the cooling system. As a side note the heater core has never been replaced. Thanks for your time, al greenfield.”
