Extended coolant life, often for the whole life of the engine or vehicle, is obtained through the use of virtually non-depleting corrosion inhibitors. Availability of the new cooler is very low. ACDelco DEX-COOL is an ethylene glycol based fluid that provides maintenance-free protection against freezing and boiling but also against corrosion. Hopefully my order went through, as I have not yet received confirmation that it has been processed. Has anyone found a coolant that mixes happily with the Chrysler purple?Īs an aside, does it not occur to car companies that keeping an obviously defective part in production for 20 years does nothing for their rep? Seriously, they designed a whole car ffs, surely they could have been arsed enough to put their own aluminum oil filter/cooler in production? The failure rate on these is high enough to have spawned several aftermarket suppliers for the same bad product. This would not be an issue if the Chrysler dealer wasn't asking $50/jug for the OEM stuff. DEX-COOL coolant protects modern engine components from winter. I see some coolants purporting to be useable in all models regardless of coolant, but the consequences of a screw-up can be dire, with the coolant basically turning into a jelly inside the motor. DEX-COOL coolant contains no phosphates, silicates, borates, nitrates, amines or nitrites. Unfortunately, it seems the OAT purple coolant used in this engine does not play well with some other coolants, including earlier orange HOAT coolants used in the same engine. Prestone DEX-COOL (orange) antifreeze+coolant (AFC) is specially designed to work with All GM vehicles 1995 and newer/GM approved formula (GMC, Chevrolet, Buick, Cadillac, Pontiac, Saturn, Oldsmobile, Hummer), most Ford vehicles 2011 - 2018 (Ford, Lincoln, Mercury) and most FCA vehicles 2013 and newer (Ram, Dodge, Jeep, Chrysler). Extend the life of your water pump and other key systems by using a. ![]() Until it arrives, and until it warms up enough to do the job, I want to nurse it along, since it is more of a weepy leak than a gusher. ACDelco Dex-Cool antifreeze will keep your vehicle running at optimal temperatures. I have ordered an all-metal Dorman unit to replace it and hopefully banish this particular demon (see what I did there) for good. The change to VC13 (P-OAT) was to move to cut costs by going to a single standard coolant instead of having VC3 (OAT) & VC10 (P-OAT) and get better low temperature performance (VC3 was better). ![]() The original (?) lasted a mere 90,000km, and the replacement I put in last year is already leaking. Well, as much as I like my Pentastar, I will readily admit the oil cooler design is a piece of crap. I tested the heat and coolant resistant on the stuff I was replacing on the way out, and it was way above requirements.
