Fixing the 1998 HMMWV

[mrandig]

Now back to the present day...

Well, that's it. Looks like I'm all out of excuses. There is nothing left to do but put the radiator back in and connect some hoses. And add some fluids - can't forget that.

Just when I thought I had run out of excuses to get this project finished.

That new radiator is bent to s**t at the upper hose connection. This didn't happen here, and the box has no damage, which means it was packed and shipped like that.

Kids, this is the reason you check your orders upon receipt. This photo was taken back in June, and I just didn't see it at the time.

I just couldn't let another day pass because of the radiator. Not after it's been this long.

Time to improvise. This tool is used to expand exhaust pipe and keep it round at the same time.


The process was ugly, so ugly I'm not showing it here. As long as nobody sees what's hiding under the hose, we'll be OK.

Needless to say, the problem is fixed.


Right side.


Left side.


Done.


Last thing I need to do is figure out the clamping situation for these blue silicone hoses, and then we'll be ready to fire this thing up.

Well, the damaged radiator couldn't stop me, but the hose clamps did.

The standard "worm" clamps, which I have a ton of, kept tearing this blue heater hose to shreds. Being after 5:30pm on a Sunday, my options were few-and-far between. If I kept experimenting, I was worried I wouldn't have enough left over by the time I finally figured out a solution.


For reference, the replacement hose is by Flexfab 5526-038.


I'm sure there's a simpler and easier solution, but I finally just ordered a few of the clamps recommended by the manufacturer. They should be here in a few days.

Until then, there's enough small things to do to keep me busy.

Looking for some feedback.

I've only got a few small items left, so I might as well knock these out while I wait for my fancy hose clamps.

I wasn't able to route the oil cooler hoses properly until now, as the cooling stack just got installed a few days ago. Of course, this would be the one time I didn't take enough pictures, and now I don't remember the exact routing. The -20 and -24P are OK for this, but both could be a little clearer.

Here's a quick rundown of the new hoses and how they're installed. Let me know if anything looks funky or weird.

Hose connections at radiator.


1st clamp at firewall


2nd clamp


Routing past exhaust


Hose connections at engine block (from straight below).



Thanks in advance!

That is one reason I stay away from that new fangled fancy stuff, plain ol Goodyear hose has serviced me well for the last 50 years

Thanks in advance!

Looks like you are getting a little too close to the exhaust with that cooler hose
