Need to put a trans cooler on my 70 mustang with C4. Checked with summit and there are a ton of them to selct from. Looks for something esay to miunt, that will do the trick and look not take away from the looks when popping hood. Also my radiator has trans cooler lines. Should I route thru radiator and then rans cooler or just plug lines on radiator.

Any suggestions?

Thanks

 

That is an option. I would route from the radiator to the cooler then to the trans. I believe the fluid travel into the top of the radiator, and flows out the bottom. Check to make sure; which line gets warm first. Be careful to secure the hose after splitting the coolant line because the tranny is under pressure, though minimal, it's still pressure and will blow the line off. Trust me, it's happened to me. Talk about messy at 60 mph. The best scenario is to cut and flare new lines or have them made.

 

Why?.

 

Pulling a horse trailer!

 

Was recommended by person who built the 347 I'm putting in and to pull my horse trailer.

 

Sertrab or Russell would be my choice. I would only use AN lines and fittings. A little more expensive, but cheaper in the long run.

If you drive in extreme cold (like way up north), route it through the cooler, and then the heat exchanger in the radiater. If you're like most classic Mustang owners and drive it when the weather is reasonably warm (above freezing) then route through the heat exchanger first, then the cooler.

 

+1 on the hard fittings, either A/N or Inverted flare will work fine, most coolers will come with rubber hoses and HOSE clamps, these suck.

I think that flared and well bent steel tubing looks the coolest, and really never fails. It is kind of harder though and will require a bender and an inverted flare tool.

 

I'm installing a cooler on my '67, running steel 5/16" line just like fuel line you get at the parts store. Going from trans. out to lower rad. in/out then to cooler in/out and back to trans in. I didn't like the idea of rubber lines and clamps so I'm going to bend my own lines to fit. I chose the B&M stack plate design cooler, supposed to be more effiecient and is MUCH more sturdy than the fin type, won't have to worry about rocks smashing it for sure. They have a few different sizes auto coolers and univ. in the stack plate type that take fittings or rubber line nipples:

Test fit but it'll be mounted farther forward in my valence cutout:

Smartest thing you've done to your car. I put one in 15 years ago for $50 and have bright orange fluid and tight gear changes no matter what the conditions since. Most modern cars have tranny coolers now.

Be sure not to mount it directly onto the rad., and also, if you put any metal mounting hardware through the fins, you will leak as vibrations will cause it to cut through. Mine is mounted with plastic mounts, and away from the rad by a few inches in the lower area in front of the rad. Plenty of space there. Good luck.
