Why would you want to? You would be better served to give it it's own cooling circuit to make it more efficient.

Customer used a turkey baster (sp) to put epoxy on his cracked exhaust manifold.

Yes, cut the end off the coolant diverter solenoid and it will screw into one of the water passages in the block behind where the cooler used to be. The circuit has to be complete and you canít just the magnet off the valve because it will burn out after a while.

Because itís only purpose is to heat the coolant and/or leak. And itís cleaner.Click the image to open in full size.

While I'm curious how the outlet elbow works, I would still keep it and run its own heat exchanger and pump.

Is this the one you posted the charge air Temps from? The ~450į is consistent with what I was trained on. The liquid cooler dropped Temps to just above coolant temp from what I remember. Target manifold inlet temp is always 100 degrees for emissions engines. I don't know why that is the magic number.

Target manifold inlet temp is always 100 degrees for emissions engines. I don't know why that is the magic number.
Intake temps before cooler removal was 130's on a hard pull on a 90*day and water temps would easily be 225*. After the removal, intake temps are in the 145* range on the same grade and coolant rarely sees much over 200* and this is on my daycab that's 800hp. If a truck thatís 300hp over stock doesnít need it I canít see how 500hp needs it. I have found zero downfall to removing the "cooler". On the 5EK in the pic the intake temp is 136* with NO cooler and a less than ideal factory CAC. It would be a huge PITA to add a second radiator and electric pump to fix a non existent issue.

My turbo outlet temp was 471* and the Duralite cooled it to 113*, not sure how you could improve that.

It's funny you posted that because I was curious how interstage would work after I read the post.

130į is reasonable.

I suppose we will just have to disagree on the usefulness of the precooler.

Well forget your training and actually take one off and see the dramatic drop in coolant temps and youíll see how useful they are.

PDI has or at least had one with a 36Ē sleeper and pulled their show trailer. I used to have a pic. That sleeper kills that one.

Sounds useful for warm up and cold weather running other than that useless
