Acert water pumps

yes they do. but you have to make sure your c-15 has
straight cut gears not helic cut gears (teeth are at an angle) 6nz and up are straight cut. some of the older e-models also. change the outside t-stat housing and plate for the water hose on the back of pump and possibly the neck to the oil cooler if there are clearance issues.

 

any of the c-15 acerts bxs,mxs,or nxs will work

 

I'm interested in this also. My 6NZ seems to get hot just looking at a hill. Was thinking of going to a larger rad. might try this first.

 

it wont make much of a difference in your heat issue swapping to the acert pump unless you do a larger rad core also. all the acert pump will do is flow the hot coolant quicker around the liners pulling the heat away at a faster rate.

 

you could also get screwed on the core charge since there different

 

The flow of the pump and the capacity of the core need to match, not say you need an acert core there are several good aftermarkets offered. Or the pump won't work with current radiator till you can get a core especially if its time to change it but to get the maximum benefit they should match.

 

If you use DCA4 in the coolant, then I would check the cover plate for it being eaten away also if you do not have a water filter, that affects heat absorption, and dissipation as does having the proper antifreeze protection -40F, and without a water filter the impeller in the pump will wear.
99% of new trucks come with power-cool antifreeze. people change to cheap ####,
Just a thought!
