What Coolant To Use

I want to change the coolant in my 05 Wrangler, and I wanted to know what kind of antifreeze coolant should I use. I pretty much just want to buy the jug and dump it in without mixing anything. Also how much coolant do I need to fill it up after its been drained?

This is Mopar approved HOAT coolant and is chemically identical to dealer supplied super expensive stuff.

That's a very old number. The newest number is 68049953AA.

Ans yes the zerex is identical.

Yep Zerex is what I would use but, its hard to find the 50/50 premix ready to use in most stores that I have found. Personally, I would just buy you two gallons pour half of one of your gallons then add distilled water to it and do the same for the other one as well and you will have the best 50/50 you can get. Distilled water is better than just DI water anyways. No metals and no minerals. The only thing corrosive is the oxygen which should not be a problem for you mixed with a good concentration of coolant.

I use ELC extended life coolant in everything I own. It's designed for hundreds of thousands of miles of use in a diesel engine. It has no silica in it so it doesn't fluid hone the internals of the coolant system over time, greatly increasing the life of things like the thermostat and water pump. I don't care what brand or type you use, if it's not ELC (always red, though some non ELC coolants are too), it has silica in it.

Man I would use HOAT (Hybrid Organic Additive Technology) using the wrong fluid is just asking for problems down the road. Trust me I have been there done that with Prestone all makes all models and after a radiator and water pump all I can say its there's no such thing as universal coolant. Its to easy to use the right coolant to begin with.

Not to be rude but you do not have a clue what you are talking about.

Just because it came in the vehicle from the factory doesn't make it the best or even the right anti-freeze.

As Ford about putting their crappy gold coolant in the 6.0 and the chain reaction that led to millions of dollars of warranty repair and legal fees from a lawsuit. They took a killer International engine design, and jacked it ALL up just by putting their coolant in it.

ELC coolant is perfectly safe in any clean system.

Maybe so buddy but, HOAT is very good coolant my system is super clean. I even changed my 98 over to it after flushing it out really good with distilled water for about a month. I noticed the water pump stays cleaner and so does the block too using it. I don't care for Chrysler much but, I do feel they did there homework on this one as well as Ford as I have not heard of any body I know with a Ford having problems. I can't speak for Diesel's but, can for cars and there light trucks.

One more thing as well I really feel the issue with the G-05 or HOAT in the diesel was simply a design flaw just like the OPDA on 05 and 06 Jeeps are. People want to blame the fluid or oil but, fail to realize it could just be a bad design or a bad lot of parts. I'm a perfect example I run regular oil in mine and have 87k with no OPDA problems whatsoever. If it was the oil causing this I would already have an issue. I think isolated problems get blown out of the water with one or two major casses.

The cleanliness is only one factor. Havent you even noticed how 4.0s eat water pumps, an thermostats, and easily develop radiator leaks? Every thermostat I have pulled on any 4.0 with cooling issues, is usually beginning to just disintegrate. It's the silica in the coolant. It's basically sandblasts the inside of the system as it flows. As far as cooling properties go, it's just fine for 50-60k miles.

Ford had major problems with the EGR coolers on the 6.0 trucks because they ran their coolant in them instead of the ELC that International did the testing with, and recommended. The coolant flow necked down and increased in velocity inside the cooler, and it sandblasted the wall between the recycled exhaust and the coolant so thin, that it would eventually seep through. Coolant would get into the EGR gasses and flow into the intake, and into the combustion chamber, then under boost the motor couldn't take trying to compress the extra liquid in the cylinder and they would stretch the head bolts and blow a gasket.

Ford tried to blame International for the head bolts, and they lost.
