6.4 coolant flush questions.

I just bought a 08 f350 6speed. Iím wanting to flush the cooling system so I know where Iím at with the coolant. I plan on installing filter before the flush. I have 8 gal of final charge already. My questions are more about what flush to use and how to refill. Read something about not being able to refill as I would in other system through the surge tank. Any info would be appreciated.

Re: 6.4 coolant flush questions.

Are you deleted? If you have easy access to the thermostat cover pop that off and shove a garden hose in there with the petcock on the bottom of the rad open. While you're flushing run it for a minute here then a minute there 5 minutes later. Then let it all drain and start over.

Don't put the filter on before your flush, you're just gonna wash all that crap into new clean stuff. If you want to see why to run a coolant filter check out the pix I just put up in the unbelievable pic thread, a few pages back from the last page.

Re: 6.4 coolant flush questions.

I’ll check that out. I’m really wondering about getting air in when refill. Some people seem to think it’s a big deal some seem to not worry about it to much and fill from surge tank and watch level

Nah it'll all burp out within minutes of the thermostat opening.

Re: 6.4 coolant flush questions.

I guess my question is if you are not supposed to fill it from the reservoir, then where the hell are you supposed to fill it?

Quick tip, fill it slowly. Leave a hole in the stream to let air out as you're filling, that way you won't have to top it off after a test drive. Kinda hard to explain. But even if you trap some air, it's really not a big deal at all.

Re: 6.4 coolant flush questions.

Agreed. And don't freak out after you drive a little bit then see half your degas bottle gone. However you go at it just try to do your best to get as much air out as possible but expect it to drop a bit after driving.

I asked if your EGR was deleted because with that vertical cooler out of the way you can get right at the thermo housing and get directly into the block with a hose. So what if a new o-ring costs $4, how much you already spend on coolant?

Ya I’m going to change thermostats anyway. And I had Sean people saying you have to fill with a vacuum fill. Whatever there called but wasn’t sure.

Re: 6.4 coolant flush questions.

I've seen those vacuum lift or whatever they're called, we actually have one. Never used one.

Re: 6.4 coolant flush questions.

Was just wondering if anyone had problems if just filling through degas bottle by a jug.

Nope. If they have, they shouldn't be working on their trucks.
