My wife was driving my 90 Toyota xcab 4x4 last winter, came in and said "Your truck is making some weird noises" I went out to investigate and first off found 3 holes in the hood, opened the hood and found that the fan had literally exploded causing the holes in the hood, destroying the radiator, resonator the alternator and belt, K@N filter, 2-3 holes in the battery which was leaking, the fan shroud and the lining covering the inside of the hood. Just a little advice to Toyota drivers, get a new fan or change over to a electric fan when the miles get high on these vehicles, it will save you about $1500.00. I got a new Flex-lite electric fan which is inexpensive and very quiet as well as easy to install. The hood I bent the holes back in and filled and then had Line x spray a permanent bra on the hood. The rest was easily repaired at home except for the radiator.
See ya.
