Probably being a pain by now guys. My coolant does not look that healthy. I downloaded the owners manual but it does not show me how to flush the coolant it tells you to ask repair shop or dealer. Do you guys know of a link that will show me how to do it? Also what kind of coolant do I use regular anti freeze or is their a special coolant? :dunno:

I use a small shop vac, take off one of the upper hoses, and vacuum out the antifreeze. If things are dirty, I will put a garden hose to the radiator hose and flush it for a while until everything comes out clean. Then suck out the water and fill with a 60/40 mix of regular antifreeze (the green stuff). Make sure what you have is compatible with aluminum, most are, but there are a few off brands that aren't.

You can try draining by pulling a lower hose, but that doesn't get the fluid out of the heat exchangers very well and you will flush a lot of antifreeze onto the ground, which may not be so good. If you do, dilute what goes on the ground with lots of water to reduce the toxicity for pets and animals...

heres my question about this subject- i started to drain my antifreeze the other day, and got a lot of it out. I have a bleeder screw on top of the engine block that you are supposed to take out to avoid getting air in the lines, so when you fill it you put it back on once fluid starts coming out of it. however; my bleeder screw is stuck and im starting to strip it trying to get it off. can i safely refill the antifreeze without using the bleeder screw? or do i have to get it out? what is a good procedure for refilling the coolant?

yep, when I refill, I just get the front of the sled up higher than the rear cooler. I use the ramp of the trailer or jsck the front end up. Sometimes I have to have someone sit on the tail to get it to sag. When you add the liquid, most of the air should evacuate. Then run it a while with the cap off, the air should circulate to the high point as long as it's "uphill" from the rear cooler to the high point. I make sure I use a box end wrench on that pesky screw on the thermostat, too. It strips EASY!

If the cap is higher than the rear cooler and all the air can make it's way out, you should be ok without having to let air out of the screw...

If can't get to drain an you Stop vac it out too freshen it up I don't recommend putting water down and having the wrong mixture if you can't be sure to get it all out. Youtube they don't have crap on newer stuff or old really!!!
