Hi all,
Does anyone have experience deleting the Auxiliary water pump under the intake? The Dinan intake on my car barely clears it, and the relocation bracket Dinan provided does not work well. I'm thinking of buying the version of the heater valve from the CSL that deletes the auxiliary water pump. If I replace #1 with #2, I'm wondering what issues I could experience. From what I can tell, the auxiliary water pump simply pumps coolant through the heater core at a faster rate, so if I delete it, does the car interior just heat up slower?
From my research, 3 versions of this part exist on S54 platforms
1. P/N 64118369807 - found on all North American E46 M3s and S54 powered Z3Ms - heater valve w/attached auxiliary pump
2. P/N 64118369805 - found on E46 M3 CSL, non-M E46 3-series, and X3 - heater valve only, no attached auxiliary pump
3. P/N 64118369806 - found on Z4M coupe/roadster and some E9X platform cars - auxiliary pump only, no heater valve
Thanks in advance!
