So the truck just got its first oil change by me and while I was at it I checked on the coolant. Well turns out the overfill was completley empty other than some calcium buildup at the bottom of the resavoir. So I took the cap off the radiator itself and there was the orange gunk crap all over the bottom of the lid and down the "pipe" for lack of better words. I thought that was odd so I removed the bottom hose of the radiator and ran some water through the top of it and a CRAP TON of orange water/gunk came out.. I did that multiple times and it just kept coming... What now?:S:

You need to drain and flush the cooling system, all that gunk your seeing is the corrosion inhibitors in the coolant have broken down. If it's very bad you can get a coolant system flush that you fill up the system with and then run the engine for a while, drain flush with water and then fill up with new coolant. Most good auto stores like napa should have it.

And be sure to flush it a few times (if you use the flush stuff), its half-way impossible to get all the coolant out of the system, and you don't want to leave the flush liquid in the system with the new coolant. Flush it more than you think is needed, just to be sure you get it all out. -Good luck!

Can you walk me through it? Basically go to NAPA get this coolant system flush stuff fill it up in the radiator itself? Not the overflow correct? Speaking of the overflow whats the best way to empty that son of a gun? I only see the tube going into the radiator so I assume its creating a vacuum and sucking the fluid from there when the theromostat opens? Not letting gravity do its thing?

Ya man, just get the necessary amount of the stuff, fill the rad and then go for a drive to circulate it through the cooling system, drain, flush and refill with new coolant. The over flow bottle is slotted into the fan shroud so just pull it (the bottle) straight up and it will come out. It will probably take a fair amount to get it out, mine is a right sob to pull up.

Walk into NAPA, grab a couple of bottles of cooling system flush, and 3 gallons of your favorite anti-freeze (not the pre-mix crap, save your self some $) then alot of people don't do it, but I'd also go pick up 3 gallons of distilled water(helps prevent corrosion I'm told). Follow the directions on the cooling system flush bottle, last time I did it, I drained the old coolant, added just (hose)water + the flush liquid, and your supposed to run the engine for X amount of time. then drain the system again after that. I'd even re-fill with water a few times over, and get it to circulate through the system a few times, get all that flush fluid out. Then drain the entire system, parking on an incline to help as much drain out as possible would help. Then top off your radiator with your mixture of anti-freeze and (distilled) water. Run the truck, that'll burp the air out of it, then top off the radiator again, and check later that day or just after driving around a fair amount, make sure all the air gets out of the system basicly. And bam, your done!

As for the overflow bottle, just pull off the little hose and the whole bottle just slides right out (lift up its just some little hooks holding it). Its mostly an over-flow catch, but make sure it has some coolant in their to begin with, just to be safe! :thumbsup: best of luck!

or trust to friendlly shop that knows what is doing. You seem innocent enough to get yourself in trouble.
Removal of water pump allows drain of block. Improssible to get all junk out of block by simplly flushing.

Hmm I don't know about improssible haha:rof.

That's my problem is I don't want to get myself into trouble with it.. Going to talk to a local shop about doing it. Thanks for the help guys!

Yes, water pump removal will get a whole nother' bee hives worth of coolant out of the block. If you have any common sense at all, and a decent understanding of basic hand tools, I highly encourage you to tackle this yourself and save a couple bucks (it is a relatively simple procedure) :thumbsup: if you need any help, just come on here and ask, or PM me anytime and I'd be happy to walk you through any problems you might run into.

I normally take the thermostat out replace the housing and hose and turn on the garden hose and start the engine let the engine pump the junk out of the system. Occasionally rev the throttle to pull the junk out of the system.
