mine too then i accidentally put gas because i was in coolant gallon I'll tell you what though while i was flushing it it came out all rust colored and stop leak was starting to cover the water lines in the intake manifold

 

That had to suck!!!!

The eBay fan I bought is dual HD 6 blade setup from a 300M. They are pretty big! It came with the harness cut on the correct side (I can use the quick connector still) and it has 4 wires. I am assuming a shared ground, 2 power, and the "remote". I was a little worried pulling them out of the box with how big they are, but they are the same dimensions as the stock radiator. I am taking them to test tomorrow.

 

I was trying to look at the 'reserve tank' aka reservoir and aka over flow tank. I didn't see one listed for the first post. I did see the Summit Racing , but couldn't pull up the the e bay listings. I was going to say that Rock Auto had a reservoir tank with cap and overflow hose for my '03 for 17.95 plus shipping.

 

Quick update: I bought another car to take the pressure off the repair, save some gas (part time pizza delivery driver) and the Blazer will no longer be a daily driver (wrings hands in delight). Replaced hoses, thermostat, radiator, water pump and reserve tank. By-passed heater core. Was replacing the broken plastic baffles but one piece that I need was broken on arrival, and the second wasn't the correct piece. As a matter of fact, I have never seen that piece on the car and conclude it hasn't been there since I bought it in 05, so I don't need it. Waiting on the replacement baffle now. It goes between the radiator and condenser. Also, they did not in fact have the condenser I ordered.

I have pics I want to post on my phone, have to figure out how on here.

I also have to figure out how to mount the fans. They are almost exactly the same size as the radiator. However, at least one of the molded mounting points on them is in the same location as the lower hose. They are heavy and I don't want to just try zip tying them in or anything else temporary. Now that it is not a daily driver, I have plans!!!

Thanks for all your comments and support!
