Re: Fan Explosion - Please read
The blazer and jimmy radiator tanks all crack on the front side of the drivers side tank directly opposite the upper radiator hose connection. Mine went around 150K. Traded the truck in during the C4C debacle last September with 267K on it. My fan was fine at that point, no signs of cracking or bad motor mounts at that point and they were all original. Suspension bushings were shot at that point, but thats about it, the 4.3L started first crank all thru its life. Probably could have kept it running for another 100K if I did all the suspension bushings, shocks and probably new rear springs, but it was time to go. May it rest in peace.
