Hi Folks,

I need to replace the auxiliary (secondary) water pump on my 1997 XJ6 w/ 4.0 (NA). The original is a Denso MNA6710AB and I just happen to have a new Bosch that is used on the X308 AJV8. I'd need to splice a Bosch connector onto the pigtail from the Denso and jerry-rig bracket mount but that shouldn't be a problem.

The question is will installing an auxiliary water pump that is larger than OEM cause any immediate or long term damage or should I not worry?

I tried to find flow rate and pressure specs for the Denso to compare to the Bosch but came up empty. Thank you for any help.

The solenoid to regulate the needed flow of coolant is by the climate ECU so any overage is automatically throttled back to maintain the set cabin temp as it normally would

 

lol a cobra pump, that’s for IC circuits. sell it for some money and go buy one of these
