My bosch pump went out @ 71k... has been on it's way out for awhile. I decided to spring for the jabsco pump for:
1. Much more flow. (rated @30gpm, will probably see less than that in our maze of a IC system)
2. Sturdier designed pump (hello 0% coolant in the summer... afterall, it's designed to pump sea water)
3. Longer service life. No more having to check or wonder if the damn pump is working.
The Jabsco pump has a rotatable head, is user serviceable, and uses just a little more juice than the stock IC pump. MEANING you can just splice/connect straight to the existing IC <10A lines/relay circuit.
Parts:
Low pressure 3/4" Jabsco 50840-0012
2x3/4 NPT to 3/4 Bung fittings
Clamps
Soldering tools/strippers
grinder/drill
4xbolts/nuts
drill (drill press preferred)
Comparison
Stock Bracket sort of "squeezes" the stock IC pump. The bracket is then held on with two bolts onto the front sub frame side. Be warned this is some pretty thick metal. I also had to rotate the head to match the bosch pump to be able to connect to the existing hoses.
Just cut off the "squeezer" drill 4 holes and bolt the pump. Be sure to have the correct size or cut the bolts so they don't get in the way when you bolt the bracket up to the frame. AGAIN this is some pretty thick metal. You'll be sitting there for an hour if you have a dremel... the same if you have a hand drill and some crappy drill bits. I used a press and a pneumatic cut off wheel.
The stock connector. I chose to cut off a good chunk and soldered it directly to it.
It bolted up and connected.
Fender liner slightly modified to clear.
Later placed my overflow tank next to it. See expansion tank delete thread.
Results: Pumps a huge amount more fluid. It's not 30gpm but it's MUCH MUCH MUCH more than the original bosch output. It's silent a well.
Notes: The IC system is a combination of 5/8 and 3/4 heater hose. The pump hoses are 3/4". Do NOT chump out and get 3/4 to 5/8 fittings. It'll pump much less than 3/4 fittings there. I thought it was 5/8s there and ended up having to go back and install 3/4 bungs there and it pumps much more. You may have a hard time finding these fittings but I ended up finding them at a mom and pop hardware store.
I would also not recommend this pump for those still using the stock IC resevoir... that'll probably turn into a gigantic volcano with that much movement.
