Have a 1999 Dodge CTD has less than 95K on it. I am going to replace hoses with goodyears and the thermostat with OEM. I figure I will do the water pump too even though it has no issue at this point.

Should I go OEM on the water pump or Gates or Airex?

Also what coolent -

Buying OEM is no longer a guarantee of quality. They are all made in China and put in different boxes with different part numbers once they get here. Comes down to how much you want to pay.

^^What he said.

Use the correct formulated coolant, IIRC it is Ethylene Glycol. Also Make sure it is Cummins approved, this should be stated in your owners manual. Last flush I used the Delo product at a 50/50 mix with distilled water....

Doesn't hurt to throw in a pint of water pump lube either.

Will Zerex G-05 work I got some of that left over from my 2004.5 change last year? Might only have to buy 1 gallon since I got 1.5 gallons left over.

the pump is so easy to change, do like i did... buy a replacement pump and put it behind the seat until needed. i have 271000 miles on the original pump and still waiting to use the new one . maybe next year

Ditto.
the pump is a easy 20min job if needed on side of road. they are not that much money$ www.genosgarage.com or check out www.rockauto.com they have good variety and prices.
