Changing lower radiator hose

Any tricks on draining as little fluid as possible? I don't have a 7 gallon catch can.

I am considering buying a new catch bin and draining a few gallons at a time. As the catch bin fills I will pour it into gallon jugs.

Pulling the bottom hose means you're leaving only what is in the bottom of the block, so about 3.5 g.

Drain from radiator petcock, use an 8mm Allen to turn, not the hex. Add a hose to the nipple if you don't want a lot of splash.

Loosen hose at radiator, expect about a quart of coolant, will get more as you move it.

I think I am going to go to the supermarket and buy 7 or 8 gallons of distilled water. Dump the water and use the jugs to drain the coolant into. Then pour the coolant back in and recycle the jugs.

Thanks for the info Jack.

Now I am thinking I should switch to the Mishimoto t-stat

Home Depot or Lowes 5 gallon buckets are very handy for this job.
Then one or two paint strainers to catch any junk that falls into the
bucket. That top hose will slowly drain past the T-stat.

One thing to keep in mind after a few heat cycles you will want to
go around and retighten any worm clamps as the hose takes a set.

I had a tiny leak on the lower hose at the radiator.

This thing is your friend in the tight space where the lower hose
goes back into the engine.





They are well worth the price in the blood and skin they save.

Unfortunately the only way to get more coolant out of the motor is to pull the block plugs, so it's going to be a lot of fluid.

I really prefer the storage containers to cover the largest areas, but they are a pita when transferring the fluids into more easy handable containers.

I agree Sean, I really like that tool too. I would have gone insane doing the cooling system in the LS without it.

I installed block drains when I did the oil cooler so If I need to drain the block I can just attach a tube and drain.

My plan as of now it to use 1 gallon jugs and drain the radiator that way. Once that is done I will use a brand new catch pan and drain the lower hose into that. Then swap the hose and put it all back in. I am not worried about losing a small amount of coolant, as I have some here but not enough for a complete refill. No one local stocks it and I have to order it at a NAPA that is about 25 miles away.

Any suggestions on what I can put on the new hose to protect it from the steering box? I am thinking cut a piece of the old hose and clamp it in place.

Thanks for the suggestion Sean, I will get one of those.

Ford had put braided nylon over some, but it did nothing. Proper clocking of the hose often is the best protection, sometimes I've seen a harder polypropylene shield used, but your suggestion will also work well.

Besides clocking, I've also cut a section of the old hose and put it over the new one where abrasion may occur.

You could save the drive if you look on Amazon and see if someone
has the coolant you use. Let UPS do the driving for you.

That looks like a better design than most... care to share a link or a brand name?

You guys are killing me, happened to look under the Ex and noticed the drag link has been rubbing on the lower hose. Can't wait for this job as I still haven't finish the shock project.

There are a couple of versions, this is one of the cheaper.

Amazon Amazon


Or if you wanted to buy the same thing as OTC branded

Amazon Amazon


In a pinch (yes I wanted to say that) you can grab them at a Sears if the local store hasn't closed down.

This is the set I have from KD Tools

KD Tools 3835 Gear Plier 7 Piece Set Multiple Tip Geared Pliers System | eBay

The work really well.
Here is a good view of the set.
After the first 12 sec you can close the player.
Also the music on this one is LOUD.

Firehouse Sub shops sell cool pickle buckets cheap if you have one of those near you. Red plastic, pretty thick, firehouse logo and white top with a nice o-ring seal (no spout) I forget the price but it's just a couple bucks I think.

Thanks for the suggestion Rusty. There is a Firehouse Subs near work but none around home. I bought 8 gallons of distilled water this morning for 8 bucks. Going to drain into the empty one gallon containers with a hose off the radiator petcock. Then refill after. If I need to add a bit no big deal as long as it is not all of it! LOL

Anyone know what size hose will fit over the petcock?
