Well after much anticipation I am back on the road, turns out the radiator was the cause of my overheating problems, it was clogged somewhere. They (dealer) ended up keeping the old one, they are going to opening it up to see where the clog is and what caused it, wouldn't be to surprised if it was the tech that messed it up. My extended warranty company, being the low life's they are, did not want to pay for the whole diagnosis process so guess who had to pay it, me. Everything came out to 250.00 which included the rental car, and deductible, I should have paid only 135.00 but considering how much nissan charged for the radiator, $578.00, plus a thermostat, labor, new seat belt, cause my air bag kept blinking, I made out ok. My new exhaust will have to wait, as well as any other project I had planned for the truck. Just thankful to have it back.
