1FASTC32's Cheep Intercooler Pump Replacement
Pump is $89.00 shipped from Diversified Products (734) 459-0130.
Pump is the same Bosch unit used on the C32, with the following two exceptions: The wiring plug is different, and the water outlet and inlet tubes are slightly smaller on the replacement pump. Both of these issues are easily resolved, as described in the following installation steps:
1. Jack up front passenger side wheel, and remove.
2. Remove the roughly 1' x 1' plastic piece that is towards the front of the car in the passenger-side front wheel-well. This entails removing three 10mm bolts in the wheel well, one plastic plug in the wheel well, and two or three plastic plugs under the passenger side of the front bumper. Remove the plastic piece completely (do not try to just bend it to access the I/C pump).
3. You will now be able to see the P.O.S. intercooler pump. It is mounted to the car with a couple of nuts on studs below, and a small bolt in the same region. It has an inlet and an outlet hose, with those stupid spring-loaded hose clamps that are impossible to remove. Try pliers and a flat screwdriver.
4. Once you remove the hoses and the mounting bolts (and the 12v plug), you will now be able to remove the pump and mounting bracket.
5. Remove the metal mounting bracket and rubber sleeve from the old pump (you may need to pry between the sleeve and the pump to loosen the rubber sleeve from the metal) and save them.
6. Now you need to swap the plastic housing piece with the inlet and outlet tubes from the old pump to the new pump, as the new pump has tubes which are slightly smaller (the idea is to move the old inlet/outlet tube piece to the new pump). Unscrew the six star screws holding the outlet and inlet tube housing on the old pump. Remove the plastic piece with the inlet/outlet tubes. Now remove the similar piece from the new pump (gold Phillips screws). Take care, as those gold Phillips screws strip very easily. Now, carefully place the inlet/outlet tube piece from the old pump onto the new pump, taking care to assure that the orange o-ring is properly positioned. Secure the old inlet/outlet housing with the gold Phillips screws.
6. Using two appropriately-sized hose clamps (I tossed those spring-loaded things, and used traditional "screw-adjust" clamps), re-connect the plumbing to the new pump. Tighten the clamps.
7. Use the old mounting hardware (rubber sleeve and metal bracket) and mount the pump just like the old one.
8. Now for the electrical. You will note that the C32 electrical plug to the old pump is completely non-usable with the new pump. The new pump has small spades protruding, where the C32 plug is for very small posts. I cut the plug off of the existing C32 wiring coming to the pump, stripped a 1/4" piece of wire, and used two small female spade connectors, which slid right over the male spades coming out of the pump. I then slathered on some West Marine Liquid Electrical Tape to waterproof the whole thing. Not the prettiest solution, but it works.
9. Refill your liquid source for the pump, and voila. Check (before replacing plastic cover and wheel) by starting car, letting it run for a minute or so, and then turning off. Go over to the right front wheel. You should hear the pump running for 5-20 seconds after turning the car off. Check for leaks.
Hope this helps those of you who (like me) are out of warranty and do not want to pad the pockets of the Stealership.
Thanks to 1FAST for coming up with this idea. Hopefully will save us all some $$$

do you know if this pump is more efficient as the stock one?
Vomit:
If you don't mind and maybe other So Cal owners would like to take a drive to San Diego and we can all do this mod together.
I'm a real goof ball when it comes to mechanics, I probably end up giving up and getting my golf clubs out to let my car have it.
the write up is really excellent... I almost want to venture on my own.

Acid test: I ran the Krap out of the car today, and it ran perfectly. . . no supercharger shutdown, even with a beating.
This is a really great solution for an expensive, unnecessary problem. BTW, how did you handle the wiring issue?

I prefer the liquid electrical tape, cuz the 5200, although practically nuclear weapon-proof, is a PITA to work with and clean up.
I wonder how long these Lightning pumps are going to be on the market? I am thinking about buying a spare.

i think i will end up buying an extra pump as well once i get all of the upgrades done...they should be around for a while, considering the amount of lightnings on the road...
you got it...
thanks for the support!
Pump is working... since everytime I turn off the car the pump is working.
Thanks.
1) The Ford guys view the stock OEM pump as bullet proof. In fact at least one aftermarket SC kit ditched the pump they had originally selected in favor of the bosch OEM lightning pump. This decision was made after several failures and at the urgining of the lightning community.
2) I did not see any upgraded IC pumps. There are upgraded IC radiators but everyone seems to view the pump as a strong point in the system not a weak point.

Excellent post BTW - it's why I love this place!

Anyone have experience with this kind of thing?...

let me try to explain what i am thinking...inorder for our intercooler system to actually cool the liquid in there, it takes a certain amount of time for the liquid to run through the front heat exchanger so that it can actually cool the liquid...if you are forcing it through too fast, then you lose the effect you are trying to create...
i may be way off here, just thinking out loud, anyone care to comment...
