Trans cooler with rubber hose.

Since I dont have the equipment to make trans lines to go to the front of the car. What about rubber lines to the trans cooler? I have seen some that take rubber hoses in/out of the cooler. Like this.


I would run metal flex lines to the front and make the transition to rubber somewhere under the hood.


Not sure how I would get them up front and not be close to the headers.

is this a bad idea?

 

I have a similar setup about 10 years, no issues. I probably need to consider replacement of rubber for peace of mind. I c no problem with your idea.

 

Get the right hose and keep it from running moving parts and off the exhaust and you'll be fine.

 

thanks for the quick answers. One follow up. I see where the previous owner cut the two trans lines on the side. Does it mater which is in and out to the cooler?

 

Are u planning to run in series w/ radiator cooler? I have mine in series w/ rad. to cooler and back to trans.

 

No i was not. I was planning to run a separate trans cooler.

 

I made AN-braided hoses with the appropriate fittings - all you need is the $, a sharp blade, and a vice. Rubber is cheaper and will work just fine though. Direction of flow shouldn't matter.

 

Like Bruce said: Flow direction doesn't matter running stand-alone cooler. I use double clamps on my metal -to-rubber hookup, esp., since metal ends not flared -- for peace of mind.

 

is there a standard size of the fitting? Ive read was 1/8 NPSM and then became 1/4 NPSM. Im not finding much in the way of braided hose with a 90 deg fitting for the C4. But then again, I could be looking at the wrong fitting. Ive been looking for 1/8 NPSM.

 

I had mine made from hydraulic hose.

 

Measure your port and find out what size you have. I used these with 90 degree hose ends: https://www.jegs.com/i/JEGS/555/113600/10002/-1?parentProductId I like frank's angle using hydraulic hose, plenty well rated for the temp and pressure and probably cheaper than $45 of fittings plus hoses.

 

I used a Derale cooler, with threaded 90 degree 3/8" fittings to 3/8" braided lines. Mounted it in the center of the grill opening for maximum air flow. Drilled two holes between the radiator and the battery, used rubber grommets, and ran the lines down and along the bottom to the transmission.
Works like a champ.

Anything is better then the radiator cooler the factory uses. But I would put just a small flare in the steel tubing you're going to put the hose on. Helps them stay on better. Seen more then one slip of the tubing.

 

I would put it in line with the factory cooler, disconnect one of the tranny lines from the radiator and run that to the aux. cooler and then route the other aux. cooler line back to the radiator.

 

Mocked up the cooler today...

Looks like I ended up buying the same one. Mocked it up today. Was too cheap to buy 90 deg 6AN, so just gonna run the hose across to the other side..\
