Radiator heater hose fitting

[JR1]

Hello, working on 75 blazer, dont think radiator is stock, on passenger side from top down it has filler neck and cap, then overflow hose, then a heater hose fitting, the fitting appears to be plastic and screw into radiator then hose clamps on that, the plastic fitting is leaking, im hopping I can get a new fitting, not a new radiator, anybody seen this, i asked at oriellys and two shops, they didn't know, they didn't seem to sharp though. Below those three things are two transmission cooler lines, and then the main radiator hose!

I would clean the area(sanding) around the fitting, look for cracks. Take out the fitting and check the threads, reinstall with a brass fitting of the correct size and thread sealer(perm a tex), then make sure the hose is supported in some fashion

If it is cracked, time for a radiator shop, or try to soldier it yourself, but I suspect the plastic threads gave out

[JR1]

Thank you, the fitting itself is cracking between threads and where the hose clamps on, where would I get a fitting this size? This seems like a common part but nobody seems to know about it.

You could start at Jeg's, pretty common fitting in NPT with barbed end. about 28 pages of fittings

what size is it? I have extras laying around

[JR1]

Dont know, thought it might break if I took it off, since it's a very slow leak I thought I would wait till I found a part before taking it out, since you seen to think I'll be able to get one I'll take it out and measure it! What is it called at jegs?

[JR1]

Btw what's NPT

Home Depot, Lowes, whatever tend to carry brass barb fitting. They usually even have things there to help find the thread. You want your barb size to be 5/8", you can use the display to find your thread. Go for brass rather than plastic.

Thanks guys, I have a home depot list anyway, ( who doesnt). I notice you truck listed, u also have a 69, CAP custom camper longhorn 350 th400.

[JR1]

Dang auto correct, I have a 69 c20 custom camper longhorn 350/400

Nice rig. I had a 71 c30 longhorn with a 402 TH400. Single rear. Had a big camper like yours an pulled my boat withit at the same time. Had a step bumper with 2X2" square tube so I could extend the bumper beyond the camper. In a moment of stupidity, I sold it years ago.

[JR1]

Well, it seems we humans get bored with stuff fir sure! I took this apart, its in the yard disintegrating until i freakout and cant believe i did that, then FIX IT UP AGAIN! It needs a more powerful motor! For SAFETY reasons of course!

Nice truck! I love seeing old truck still working. That's an impressive load it's hauling.

I dig the buggie too. My father has has a 73 VW Thing since before I was born. I learned to drive stick in that Thing.

[JR1]

Thanks, the c20 longhorn handles the weight fine, the 350 motor complains the whole time But made it to the desert and back a few times, SO VINTAGE ITS FUN, camper is a 1971 vista Liner!

[simicrintz]

[JR1]

Old yz250 's, 2002, good bikes, WE SUCK THOUGH! BUT LOVE THE DESERT

[simicrintz]

As long as you are having fun it doesn't matter what you are on! I'm on a '08 Honda XR650 and a '19 KTM 500 EXC; 40+ years on 2 wheels and ain't done yet! Sorry for the thread hijack; I like Blazers but I also like dirt bikes!

[JR1]

I got sidetracked on a steering issue, thread is about blazer steering, but I got back to this issue and found the npt brass fitting at Lowe's, used thread sealer and made a little support for the heater hose. Thanks guys, see you in the next problem!

[jaros44sr]

Glad it all worked out for you

BTW, I ride a suzuki drz dual sport, great for the road and some trails
