The radiator on my son's '05 Tacoma 4x4 with 4.0LV6 recently failed after adding coolant because it was low and running hot. He had driven it another 20 miles, but says the temperature gauge was remaining normal and it appeared to be running fine. When it first got hot, he stopped before it got into the Red. When, later, the radiator ruptured, he turned the engine off immediately. I had it towed home, and, not suspecting anything other than the ruptured radiator, so I went ahead and changed out the failed radiator myself, no problem.
But it was when I was first cranking up the engine after the initial coolant refill that I realized I had a bigger problem on my hands. FWIW, I always bleed coolant refills/top-offs on cold engines with the cap off. And, it usually burbs and gurgles as trapped air makes its way up. But if you take a moment to look at the 19 second video I've attached, you will see that it's blasting out way more than trapped air.
I know at the least, a head gasket is blown, but with that much force, could my woes include warped or cracked heads? I've read many mixed feelings about how long you can drive above normal engine temp before these 1GR-FE engines suffer permanent damage. And, because i really don't think the engine was run for more than a few moments when the temperature really climbed out normal range, I'm just not sure it's more than the gasket. The truck has 205,000 miles. Can't be sure if the previous owners ever had issues, but at least up til now, it has not been a problem for us.
At the end of the day, I'm going to have to have it towed to a shop. But I'm so leary about paying to have it broken down just to tell me I have a cracked head as well. And, at the same time, my gut feeling is that if it was in fact something really bad like that, that it would be far better to replace the engine than pay $4K+ for a complete rebuild. On the other hand, it may just be the gasket having failed from age, and nothing worse. But would a failed head gasket alone push that much compression & gas into the cooling system to result in what you see in the video?
Thanks for any thoughts you guys can share!
