One day last week I drove about 60 miles to a trailhead and then drove about 15 miles of moderate trail (with a short section or two of steep crawling and one big creek crossing) to a property for work. Anyway, it was a fairly warm day and I wasn't easy on the truck. On my way back home on the interstate going about 65mph my engine cut off and was overheating. I was able to coast over to the side of the interstate and got a tow to my house. Antifreeze had spewed all over the engine bay so I went ahead and cleaned everything. The next day I inspected all hoses and could not find any obvious leaks. PO had an aftermarket radiator cap so I went ahead and ordered/installed a Toyota cap. I drove it about 1/4 of a mile down the road tonight and then back to my driveway. When pulled in it was overheating again. This time I could see that fluid was pooling up at the bottom of the radiator but not hitting the ground and had sprayed up against the air cleaner. I also noticed that my fan shroud was a little loose and that one of the fan blades was chipped. Chip in the fan blade could be old but its new to me. The motor was obviously very hot but the top of the radiator was cool. Seems like I might have a clog causing coolant to spew/leak. Looks like the original radiator to me and not in the best of shape. Lower radiator hose looks fine but I will probably replace anyway. Anyone else had a similar issue? Thinking about a radiator flush (did this 2 years ago), new lower rad hose and new thermostat (7 years or so ago). Resevoir has fluid. Anything else I should look into?
