I'm Awesome
Today was #4 and the most spectacular, explanation below, but first, pictures
Why would my truck keep blowing up water pumps? Never seen anything like this before.
First pump cracked by where it attaches to the block last november, while I was doing a crank relearn. At ~4500 rpm a burst of steam came from under the hood and I found this:
Being the pump that was on the truck when I bought with ~175k miles on it, I didn't think too much about it.
Pump number 2 was a Duralast from Autozone. It didn't crack, but started weeping coolant after just running in my driveway, at about the same spot.
Pump number 3 was a warrantied replacement Duralast, that failed at the same spot the first one did, and doing the same thing.
Pump 4 was a Napa unit after I returned Duralast #2 in disgust and drove across the street. Exploded at about 4k rpms, again, no load, in my driveway.
Other weird cooling issues since I bough the truck:
-blew the lower rad hose while pulling my trailer up a pass. It ran really close to the AIR pump pulley and wore a hole in it. Thought nothing of it. But the truck was getting hot as well, about 230F, before I pulled off at the gas station.
-blew the hose clamp APART on the lower rad hose after installing pump #3, on a short drive. Figured the hose clamp failed.
So what the heck you guys.
My only theory at this point is a blown head gasket sending too much PSI into the coolant system and BOOM.
Help!!
