hmm, I guess the factory cooler does a better job than I assumed it would. It will be interesting to see what you notice once you have it all running in regards to temps

Yes, it would seem it does a good job of cooling the fluid. It would be great if the fan wasn't needed at all, but I expect it will be, especially in bumper to bumper traffic in summer or when I load it beyond factory specs. I've seen my van's aft reach close to 200 creeping along the 401 in summertime. Driving around town with lots of stops and starts, in the heat of summer, will put it in the 170 - 180 range generally.

Passenger side plumbing finally done

I had to order two different silicone couplers and modify the piece of piping that came with the kit. Although it looks tight, it's not touching anywhere. 90% of any flexing will be on the section of coupler that connects the portion of the charge pipe that's bolted to the engine and the intercooler coupler. There is also a coupler that joins the engine charge pipes that is quite flexible too despite being bolted to the A/C compressor. I rocked the engine back and forth (torque/rear engine mount is still not tightened down) and there is no movement or contact of couplers or piping on any chassis parts. Again, flexing is confined to the couplers that basically join the chassis and engine mounted charge piping parts.



My ATF cooler outlet hose is slightly touching the intercooler coupler, not even enough to deform the circumference of the hose. However, I have discovered that I can pick up a transmission return line from a 1992 - 1997 Jeep Wrangler or Grand Cherokee (or Dorman P/N# 624-384) that will work in this application. It's a very short, 3/8" elbow that should redirect the piping immediately after leaving the cooler so that it doesn't make contact with the intercooler coupler. A local scrapyard has a few of these vehicles and they told me I was welcome to go into the yard and help myself, if I can find one.



Final result. I did have to use one traditional hose clamp as opposed to a "T" clamp on the curved section of pipe. I did this because I needed a narrower clamp as I had to cut the pipe close to the curve. I did get a great bead roll on it and the clamp cranked down nicely on the right side of the bead roll. Would I want to put 35 psi through this piping? Probably not, but it will easily handle the 7 - 8 psi I'll be feeding it.



All of the piping is done with the exception of securing the 3" intake piping to the back of the valve cover. That will be done tomorrow hopefully. Then, the vacuum hosing and trans fan wiring will be completed. I'll be into the F/IC wiring by mid next week if things go as planned.
