It was a 5 ton weekend !

Got a chance this weekend to kill a few rats on the 813,not literaly but project wise.Started by flushing the cooling system.The trucks got about 4000 mi. on it since depot rebuild and the antifreeze did'nt look all that great.
I removed the bottom petcock valve from the rad. and let it go.Typical brown crap along with the black at the last.Did that a few times and flushed with hose water.Then I removed the thermostat and put almost a half a box of cascade dishwasher detergent ,powder form (mixed with hot water),in the system and ran it for about a half an hour then dumped it.Then filled with water and repeated for a few more times till the water on the dump looked nice and clean.
I then drained as much of the block as I could by taking out the petcock on the side of it.Then installed a new thermostat and gasket and a coolant filter set up along with a block heater.Filled with almost 9 gal. of Chevron 50/50 HD antifeeze.No leaks!All is well.While under the hood I installed one of jwaller's oil filter spin-ons,with a NAPA 1970 XD filter.Way better!
Lastly I put the truck up on blocks and removed all ten tires and wheels with the spare to exchange for a set of Michelin 11.00-20 XL's I'm getting from Hundy next weekend.Should be cool!

You might want to consider buying a new water pump to have on hand. Every time I have gotten that aggressive with cleaning out a cooling system, the water pump's seal failed shortly afterwords.

Thanks Ed.I briefly thought about going with the super singles.Glad I did'nt.Doing the remove on those was tough enough.

Stumps,I may do that.

what filter setup did you use for a coolant filter?

that truck makes those jack stands look pretty small

I was thinking the same thing, I had a set just like that grenade apart under my 813 a couple months ago.

I got those from the heavy equipment shop where I work.They're either six or eight ton rated each which I think is adequate.I put plenty of wood under it though,way plenty!
