Hi all, thought my 5/8 hoses were leaking before my transmission cooler but it appears to be my cooler instead. What are my options as far as what is available? How difficult is it to change out? Can I bypass it for right now? It's hay season & I need my truck.Thanks,Dave

Cooler at front or heat exchanger on drivers side of block. Just want to make sure we are talking same thing.

Hi John, heat exchanger on the pass side on the block. I called the local Cummins dealer, he had me sit down before he gave me the $3,000 price for a new one.

Can I get a used one & where?

Thanks,

Dave

I would need a how too in the R&R on this one. I don't know anything on these units!

Thanks again,

Check out CF and post a wanted

I think its not required - as the transmission cools by the cooler up the front - its actually the exchange to allow heat to exchange into tranny when cold. Or something to that affect.

should be easy enough to replace - but might need to take turbo off .......

will try and find a thread that might help .......

The parts stores said it was a Cummins part. I did put a WTB on CF like JohnFak suggested. I'm still looking, may try rad shop as well, Dave

When i had my trans rebuilt i took my cooler off at the advice of my tranny guy to flush it out and to remove the check in the line. He has seen the checks plug up and restrict flow. Since their only purpose is to keep the fluid from draining out of the cooler and back into the pan when the truck is off, he said I was better off leaving it out. When I pulled the cooler out, the only thing i remember removing was the intake elbow (for better visibility). Its a bit of a pain working around the turbo but I didnt want to mess around taking it off. Youll have to remove the two coolant lines ( youll lose a decent amt of coolant so be ready to catch it or drain some out before you pop em loose) from the top side, and the two trans lines from underneath. If i remember correctly theres only two bolts holding the cooler in place. While your underneath removing the trans lines take a good look at it you should at least be able to see the bolts from down there.
