What type of engine coolant is required? The owner's manual specifies HOAT coolant, but I have not heard of this. Can someone explain?
I plan to add coolant to my 2007 Dodge Ram 1500 pickup. The owner's manual
specifies HOAT coolant. I have not heard of this. It appears to be a light red, maybe
orangeish color. If I drain & flush, can I replace with the "pink" DexCool?
just use the green stuff from like napa or pep boys, it mixes with any thing
Mopar® Antifreeze/Coolant, 5 Year/100,000 Mile Formula (MS-9769), or the equivalent ethylene glycol base coolant with organic corrosion inhibitors (called HOAT, for Hybrid Organic Additive Technology) is recommended. This coolant offers the best engine cooling without corrosion when mixed with 50% Ethylene Glycol and 50% distilled water to obtain a freeze point of -37°C (-35°F).
Its all the same really. my 05 cummins came with the pink stuff, i used the green stuff to top it off after doing a thermostat, no ill affects. its just a way to rape you for money. itll evaporate before you get 5 years or 100,000 miles out of it.
Go with Zerex G05 it cheaper than mopar with the same protection. What Dan it will evaporate? You sure its not a leak somewhere you got. http://www.valvoline.com/products/brands/zerex/antifreeze/42
never mix the green with the red,you will be in troubel then,it is the mopar version of dex-cool,DODGE has its own type of collent for a reason,use what it says.
@andrew i had a bad head gasket and it was using coolant on cold starts i figured that out. but either way the green stuff is just flat out ethylene glycol and water, which is why its safe to mix with any thing.
dont mix them. use what what dodge recomends, they have spent a ton of cash researching works best in their engines. also mixing or switching to a coolant that doenst meet recomendations can lead to seals and gaskets failing, cooling system plugging.
ive had bad experiances mixing them if your flushing the whole system then use the green to refill its cheapest and from what ive found most effective but if it has the pink then top it of with the pink but dont mix them
use evans it has no water so it wont boil
I been running 50/50 in truck can I use red any freeze in truck 2004 Dodge pick up
