Re: installing coolant lines

why not use rubber lines? I think its alot easier to install and can look alot better. Some nice steel braided ones and some nice fittings on the radiator would look good.

Re: installing coolant lines

just get some barbed adapters it think its 1/4" npt male to 3/8 barb fittings for the transmission and radiator or cooler and some hose. Pushloc is the best/easiest. doesnt require any special tools. I still put a hose clamp on it though even though they say you dont need one. just make sure the hose you get can with stand 250 psi 300 degrees. Then get some brackets to mount to the frame or inner fender for routing the hose and your set.

Re: installing coolant lines

I have read articles that state the factory metal lines do a good job of cooling the trans fluid. If you will notice our power steering pump has a metal line that runs and makes a loop under the radiator and acts as its cooler. Rubber will insulate the heat. Every 10 degrees you drop in trans temp adds 10.000 miles of life to the transmission. They make tubing benders and they are a pain but it is still the best way.

Re: installing coolant lines

Ill disagree with that. with how fast the fluid is running thru the lines I doubt its losing that much heat considering your running it thur a radiator that has 180 coolant in it and the fact alot of newer manufactures are using rubber lines. My powersteering is metal for about 6 inches on the high side then to a compression rubber line and return is all rubber. Rubber lines should work just fine. Your metal transmission pan will do a better job at cooling than the lines that are running right by your engine and exahust will do. and with rubber lines are easier to install a aftermarket cooler in front of the radiator which will do way better than the metal lines and the radiator cooler.

Re: installing coolant lines

A finned aluminum pan would be very helpfull with heat. Aluminum transfers heat better than most metals. Old school radiators were copper now they are all aluminum. I never understood why the trans cooler was in the radiator where it is 180 plus degrees. Having the radiator right in front of the engine blowing all that heat back on the motor that it just took the heat from is also a dog chasing its tail. I think a small cooler with a fan built onto it mounted below the battery box horizontally would be a good place for one and it wouldn't clutter up the front of the condenser. One might fit near the rear of the car somewhere if you used the rubber lines. Just thinking out loud. The nascar guys have a rear end cooler mounted in the back of the car circulating the rearend fluid by a belt that fits on a pulley on the rear driveshaft yoke. Those guys are very creative.
