Any tips for replacing the heater hose quick disconnect?

[AuroraGirl]

Thank you, that's what I was looking to know. My understanding is that it's 1/2" NPT threads and just a standard hose nipple will work with the same size heater hose as the rest of the truck?

You can tell I'm new at this aspect of working on my truck. And I'm a serious over-thinker.

Thanks a lot for the help.

id go further and use a band clamp that either has a T of a screw off it or goes in circular like this

the first one i mentioned is a ford thing I think
that or buy appropiate sized spring clamps


Fun fact, a local FARM of AG supply store LIKELY has these clamps i piced above in stock. Apparently its really common on pump hoses for sprayers as well as high volume, high output transfer pumps(think milk, large quantity fuel tanks, etc). Im guessing that they hold the seal better than the much-likely-higher-than-16-psi that worm gear clamps are usually fine for.

i have worm gear clamps on some of my stuff and they usually work fine.. but i found the newer lower quality ones are... well... frankly just ****. they either cut into the hose(too little Surface area, sharp edges, etc) or they literally cant handle their own clamping forces and the little steps they use pull away and bend, thus loosening. eventually may break from fatigue if the pressure lowers and raises(as most cars do daily)

this is what i tried to post before. unlikely to be found in small OD sizes at a farm/ag store but you may

they work fine. on a heater hose that wouldnt be hard to reach normally speaking, just align the clips parts people have issue getting off to where YOU can reach them and the hose will in the future naturally like that resting spot. in addition, the tool for these is invaluable on moder nvehicles. could live without it on a square but AMAZING for everything else nowadays

heres your breathe easy solution i have a cheap one thats been abused and i just wheel the rust off and oil it everytime i need it(some pot metal contraption, its indoors and dry and its just rusty all the time)

Got it all back together today. I ended up not putting in a restrictor as it really doesn't look like there was one in there to begin with, although I suppose it is possible that the hard line itself restricted flow. Now I'm paranoid lol.

I routed the hose through some of the loom that the old one was in and then zip tied it to the old bracket, too. I also zip tied it at the AC condenser just so it would not flop around.

I filled the radiator as much as I could, then fired it up and let it warm up until the thermostat opened. When it cooled, I was able to put more in. Then took it for a spin around the block (a 6 mile circuit that includes 60mph highway) and it performed flawlessly. Fixed!

I would mount that hose to that unit with a rubber vibration barrier. I could see vibrations over time fatiguing the ac lines to kink//break or the hose rubbing if it was loose for the heater core. Certain plumbing clamps would work great and could be mounted with like wire or zip ties themselves. Just keeps the water pump and system pressure from affecting it

Yep I'm going to isolate that with, if nothing else, some of that same type of loom used elsewhere on the hose. I'll look at the hardware store for other ideas as you mentioned. Thanks for bringing it up

I replaced the one in my 99 with the factory part. The new ones are a different material. A lot of times it is just the o-ring leaking and you dont have to replace the whole fitting. They do tend to break and can be a pain to get the remains out of the aluminum intake. I have had to cut them into pieces Don't waste your money on the extractor bit they sell in the parts stores.

This is all true. Good post.

@geocrasher . good job..pullin that hose nipple out meant to me that it had already been fixed.
Funny Mr.Goodwrench fixed it himself to match that engine's fancy warranty..(when it was new of course)....that said...if Mr.Goodwrench himself installed it, reckon it doesn't restrict the flow any huh? Good to know.

What else was I gonna add...?






Oh yeah.
I was wonderin why you don't ever stand there with a rag in your hand under the hood?
It's looks like there is a TON OF POTENTIAL under that there hood on that there squaarrre body chebby man, ya ever think about wipin some of that stuff down any?
It's so dirty.
You like it dirty?
.
..

I would enjoy detailing that engine bay Geocrasher, maybe we could help.
You don't wanna?
Look!
Somebody was workin on it! A little..


Hold on

be like

You know what im sayin?



Y yer firewall is so dirty?
I thought you said ol boy put an engine in that truck.


That's the best place to start imo







Some people, myself included, actually enjoy mowing the grass for example. I find yarkwork very relaxing hot or not.
I also find the same escape and relief detailing engine bays and it is even more rewarding because it stays longer.. If I can break a sweat that's even better!



Just sayin.

Yeah it's a bit crusty, innit? That's alright- I have spent very little time under the hood of this truck. I'm not the one who put the motor in or anything, I just bought it as-is. It definitely needs a good cleaning. At some point a rodent left little bits of himself on the intake manifold. Gross. I'm a bit afraid to take it to the pressure washer and attack it, but perhaps its time to buy some degreaser and attack it with the hose here at the ol' homestead. If you have any suggestions for tutorials on doing a cleanup, I'm all ears!

Cover all electrical systems tightly with thick plastic , even broad parts of engine bay.
Pressure wash non openings that have grime

then degreaser sensitive areas

I have good experience with PB Blaster.

I swear by PB

 

[geocrasher]

Thanks @82sbshortbed that was helpful. I watched the video, looks like I have another project to get done Also gives me an excuse to buy a shop vac or an air compressor. A friend just tossed one too... and I turned it down because it didn't get high pressure. I wish I'd taken it!

Seafoam deep creep has treated me really well

 

[Rusty Nail]

Aww ****! "Dude got butthurt and now it's on the silent treatment" - for days!
I aint pickin on ya dude it's just pokin sticks is part of the fun. Plus we want moar pix.
Maybe I was just talkin **** thinkin we could get @AuroraGirl to show up.

Oh if you think I was offended or something, you're talking to the wrong guy. I can take the heat and dish it out on occasion. Right now I'm working toward a bunch of other fixes, but an engine bay detail is now on my list. It also has me wondering if I could do something to rejuvenate the paint on this old rig.

 

[AuroraGirl]

I, for one, find the level of offense to be low... to be offensive! Where’s the butthurt when you need it(intended pun)


I forget his name but he’s banned for his very aggressive political views toward everyone and really stopped participating in threads and ultimately just want3d to argue because he would ignore if you said something agreeing or would argue something he presumed you would say instead of what you say, so you could say something in mostly agreement and he would retort as if you suggested his grandma be executed and puppies are bad

him, we need more of him
