LMM Radiator Hose Removal ... How The HE!! Does it....


EDIT: How does that lower radiator hose come off ? It has an odd looking clip of some sort and I don't want to break it


A DIY radiator flush and refill is on my short list when the weather breaks a bit. I poked my head under the truck today but didn't see a drain anywhere, I guess I just missed it. Which side is it on and is it hidden behind something ? Admittedly, I didn't have a flashlight and I should have.


I was just going to drain and refill with water a few times until the water drained out clear. Anything else ?

Why DIY when you can take it somewhere that has the proper equipment and machines and can get it done better then DIY?

Ryan,

I see your point......to a point. I am not always a fan that a "shop" can get it done better than DIY.

I am extremely picky about how my maintenance gets done and paying a minimum wage "mechanic" to work on my truck ain't gonna happen.

Aahhyes, I think there are two drain plugs on the block that you can use to drain the old fluid. I know on my 03 there was a pep-cock on the bottom of the radiator but I am not sure on the new trucks. I have the same truck as you do but haven't changed my fluid yet.

I do my own maintenance, that way I know it's been done correctly. Period. I would probably consider having a shop do it if I had high miles/years on the original fluid but I don't. I bought the truck new and will change it soon with under 4 years of age and 40K miles. Still in pretty good shape I would imagine. After a couple drain/refill/run cycles, it'll be just fine. We have a big trip planned out west this summer and I'm going through the maintenance checklist. I like to be ready, or at least try to be.


I recall reading about having to remove the lower hose clamp to get the fluid out. I guess I'll get back under there with a flashlight when I can.

2006+ radiators do not have a drain. You just pull the lower rad hose and make a mess...

Yes, its stupid that they got rid of the drain plug on the radiator, but if you really think about it, modern Dex-Cool is good for at least 150k miles...so how often are you really going to have to deal with it??? Not that often.

I guess that's what I'll do then, remove the hose. ...and yes, the book says 150K miles OR 5 years, whichever comes first. I'm a year early on the coolant swap but I don't mind. I'm doing everything else as well. Thanks for the info on the hose.

Bravo on doing it early. Your only asking for trouble if you try going 5 years on this stuff.

The silver clip is "C" shaped with indentations pre bent into it. Right or wrong when I drained mine I just used a needle nose pliers and pulled on the center of the C shaped clip. It came off very easy.

OK..cool..got it off.

Now.... getting the hose off ? Is this where I push on it from below to loosen it and get a face full of hot antifreeze ?
