Whelp... Having my first issue with the Tundra. On the trip home from work yesterday, I looked down to see my temp gauge climbing over into the red. Let off the gas to pull over, and it started creeping back down. Called my dad (a mechanic), and he said it was likely a coolant hose collapsed, given the symptom of only happening during acceleration. He went on to say, if it ran hot, check your radiator, it's probably busted. Sure enough, hose is squishy, and radiator has a leak from over heating. Anywho, a trip to eBay and $350 later, a new radiator, hoses, and thermostat are on the way. I'm not mad or upset. I figure if I only have to throw in $350 every 261000 miles, I'm getting off easy!
