Re: Sad day.
Just so you know.... Bill is spot on with the block being properly cleaned. I bought a Goodwrench 350 for my Blazer. GM has specific guidelines for the instillation, one of which is having the Radiator cleaned or a new one. Shortly before the previous engine went down I had replaced the Radiator, so flushing it before I did the R&R was a no brainer. Fast Forward to the engine is changed and it runs great except.... "HOT" ...way hotter than any of the previous engines ever ran, and sitting in traffic would make one very nervous... So since its under warranty and I have receipts, I took it to the dealer. They only looked at the truck for a second and said CORE SAND. They didn't offer me a loaner, but they took the truck in on warranty and whatever they did, when they were done the service manager showed me a plastic bag with about a pound of core sand. The Radiator had been removed and a new thermostat had been installed.......Point being if the core is full of crap, its gong to end up in your Radiator.
Ideas are like children: there are none so wonderful as your own.
