what p/n or thermostat temp do i need for my 01 24v ?? ive come up with no less than 6 p/n,s for thermostats??do i need a 180 or 190 for light/medium towing and any recs on antifreeze??thanks bws

 

please buy from cummins as there has been several updates......ask hoss

 

at 58k not sure if i should throw a t-stat in or not??am going to flush system tomorrow.

 

why are you changing it?if its running hot clean the radiator out,pull it out and preasure wash it it will probably solve a heat problem,my 01 was running hot,and if you replace your thermostat put a cummins one back in,go to a dealer and spend the money i tried others in mine and it ran hotter,good luck

 

should i use tap water or distilled water for mixing with the antifreeze??i hear diferent stories on this?? the stat p/n they gave me from cummins is 3946849 and is 56.00 and the seal is extra$$ ouch.does this seem like the right 190 degree stat??

You might like to consider this coolant.

I have this in my 2000 and am going to put it in my 1997 as well.

I think the coolant manufacturers recomend using de-mineralized (soft) water.
