pull the lower hose off the rad. thats the way it is on the LBZ. do not lose the o-ring.

 

drain on ground
walk off like a bawse

 

i like to let gravity do the work lol

 

It's going to be a mess.

 

Use a kiddie pool to catch the mess.

 

worst design ever.

 

Big plastic storage bin is what I'm going to use, and give the old stuff the auto hobby shop.
Going back with new coolant and distilled water.

 

How often should you drain and replace the coolant? I've never done it yet but I'm thinking it might be time? My truck is 4 years old and I just bought a huge 5th wheel.

 

i run a hose from my drain to a small river so it doesnt make a mess

 

Haha this made me smile

 

IIRC every 50 thow

 

Great..Thanks-I'm at 48k now

 

70K on mine and it looked like new... if looks matter.
Nice design on the lower radiator hose connection though. Very quick and easy to drain. Gotta remove the passenger wheel well (like every other project), pull the wire clip and wiggle it off. My storage bin 1.5' x 2.5' was just big enough to catch it all.

 

dont forget to burp it

 

Or while you have the downtime grab a 1-1/2" x 6 stainless nipple, two 1/2"x3 stainless nipples and a 1/2" ball valve. Weld/drill tap into the big nipple dead centerwith the small one, add valve and put the other half inch nipple on the other side so you can connect a hose to it. Split lower hose and slip it in. Took half an hour and no more mess!:drink

 

Hmmm . . . a Fumoto valve for the coolant. Great idea, thanks. :thumb

 

Run Permanent CAT coolant, good for 6 years or 600,000

 

Here's mine . . . by the way - it's a welded 2" i.d. pipe.
The hose clamps won't take all the slack out with the welded 1.5" piece.
Ask me how I know this.
