coolant issue

ok so last decenber my 05 WK had some major engine problems (warped heads). so me and a buddy decided to do the wokr ourselves. now its been almost a year and there have been no fluids in the engine such as coolant and oil...now i got the oil and filter and new spark plugs but as far as coolant can i put in prestone 50/50 or do i need to go to the dealer and get the ""FACTORY COOLANT""...im not quite sure and i dont want to put the wrong coolant in. thank you

Re: coolant issue

They say you are supposed to buy the factory coolant. but after i changed my water pump/thermostat and did i flush i put in some coolant full-strength diluted by me. Says on the antifreeze its good for any color antifreeze normally used in a car and good for any brand. This was a year and a half ago and works great. Factory coolant so expensive

Re: coolant issue

on the 4.7 you have to use the factory HOAT coolant blended with distilled water

because not using HOAT can destroy your water pump and damage your engine

Re: coolant issue

mixing prestone with the hoat in your engine can cause the coolant to form a gel and clog the system. if they are mixed you will need to flush the system

Re: coolant issue

Re: coolant issue

Im pretty sure all mopars require it. It takes a while for it to eat away at the plastic parts in the water pump.

yes, hose water is not pure. just buy a few gallons of distilled water, it is dirt cheap

Re: coolant issue

so ur saying i can run straight distilled water or prestone with distilled water? i read that if u dont use HOAT it can ruin the plastic impellar...but i think my water pump came with a metal impellar on it so would it make a difference?
