Trans coolant line fittings

Happy Saturday Everyone. I stupidly bought a chineesium alum rad for my '68, well the rad came with metric fittings for the coolant lines, and of course the coolant lines themselves are standard. Anyone else here have this issue, and where did you find standard to metric adapters. I have not looked anywhere yet, i was just hoping someone has been here before and knew where to get adapters. Thanks,Terry

Re: Trans coolant line fittings

Man... No bueno. Guessing you canít just return it for the correct one. There are lots of adapter fittings out there, but Iíve not seen metric to US flare adapters. Your easiest fix might be to just buy a short length of 5/16Ē line that already has metric fittings on each end. Cut it in half and put the appropriate bend at each end then cut your existing lines to length and use a double-ended compression coupler to graft them together.

A previous owner of my Ď68 had rubber lines hose-clamped onto my original lines and they held just fine. Prior to replacing my lines I used those compression fittings to graft new ends on and they never leaked. Iím told the cooler lines only run about 30 PSI.

Re: Trans coolant line fittings

Not2fast, Good Idea.

Any4xx, Cannot return rad, i bought it 5 years ago. I like your idea using hard line, i have used rubber lines in the old days, but feel better using hard line. I have owned this car for 6 years, i have never driven it, and i am so close to having her running again. My goal is to have it running by the 15th, my birthday. Thanks for the replies, Terry

Re: Trans coolant line fittings

Your local Hoseman or what ever name they go by up there can probably make a hose for you with different fittings on each end. Give them a call if you want solid hoses.

This will work too. Most of the add on coolers like Hayden use this method.

Re: Trans coolant line fittings

Absolutely go with an external cooler, don't use the in-tank cooler. Get a plate style cooler, not the finned tube style.

Re: Trans coolant line fittings

Hi All, This is an update to the I am an idiot thread. I started this thread asking for an adapter to go from standard flare to metric male flare. I spent 3 hours today looking on line for what i needed. I went to the garage to take a pic of the trans line fitting and the rad fitting. While i was there i tried once again to thread the trans fitting into the rad, well sumbitch, it threaded right in like it was supposed to. I have tried to mate these two multiple times, and it always felt like it was cross threading. Man , i feel dumb, but relieved too because my problem is solved, and tomorrow, i will try to fire the beast for the first time in 6 years. Terry

Re: Trans coolant line fittings

Glad you got it fixed. Now drive it down to your local auto parts store to get that external cooler.

Re: Trans coolant line fittings

This was definitely a positive motivator to help me get my car running and driving, sometimes a minor setback kills momentum, but i told myself when i bought this car that i would do research before attacking a project, and not be in a rush to get it done. I took lots of pics when i tore the car down and those pics have helped save my a$$ a few times. Thanks for the positive comments. Terry

I think weíve all been there. Iím just glad youíre back on with assembly. Those little annoyances can certainly kill your motivation though.

Re: Trans coolant line fittings

Well i made a valiant effort to fire up today but little gremlins slowed me down, i started filling the rad, using only water , just in case, well dummy left the block drains open during install, but did flush out some gunk. Transmission plug had cracked at some point, leaked fluid on the floor, stabbed the driveshaft in real quick, cleaned up mess, carried on. Got everything set to fire, turned the key, and













Nada, but hey, my new clock works! I was using a 13 year old optima battery, and it's no bueno. So later this week i will buy a new battery , and try again. Terry

Re: Trans coolant line fittings

Update to my previous update. Today, the beast lives again. My wonderful wife bought me a new battery for an anniversary gift yesterday, i put it in this morning and once again, nada, no click, nothing. So i went over all the wiring looking for obvious issues, did not see anything wrong. Went back and looked at the last thing i touched, the console wiring , which contains the neutral safety switch,i looked it over and determined the it was not plugged in all the way. Once i did that i tried again to start, this time it Fired right up, and startled me cause i forgot the open headers. Woo Hoo! I am so relieved. This is the first time in 6 years my car has ran.
