We are a community of Pontiac enthusiasts. The purpose of our community is to keep alive the Pontiac spirit by sharing (or showing off) our cars, discussing Pontiac, helping each other work on our cars and find information, plus attend various meets/shows/etc... To aid discussion, sharing, event planning and selling of parts/cars/anything, we have various parts of the website to aid this from Forums to an online Garage to Classifieds to even a Document Download Repository. You can find links to these in our navigation above based on what each section helps with (discussion, local events, learning, etc...).
We invite you to contribute, find help or just view some of our member's amazing cars! Don't forget, we also have great contests from time to time (like our Pontiac of the Month and yearly calendar contest) and our Pontiac This OR That, a fun game where you choose the best of two randomly selected Pontiacs from our online garage.
We look forward to seeing you around!

The water/coolent in the engine is really rusty and $hit brown from sitting a long time. I want to isolate and flush the block by itself. Meaning I dont want to flush that ugly brown water into heater core and rad. (I'll do those seperately as well). The water that came out of the rad. is clean looking so no need to run rusty water thru it Im thinking.
My thoughts are to attach hose barbs to heater hose at the rear of the engine and the hose at the water pump. Screw two garden hoses to the ends and connect one to a faucet and the other to the drain. I think I only need to pull the lower rad. hose and plug as the upper has the thermostat which should be shut .
Does this sound right?
And which way should I make the water to flow? Does it matter?
After it comes clear I will flush with a Gunk Rad. rust remover product.
Any thoughts or advice on this would be appreciated.
