I don't reach the 100,000 mile mark before 5 years. Is the pink mopar HOAT coolant done after 5 years? I changed it initially around 5 years and like 83,000 miles. I'm at 10 years and 123,000 now.

Generally long life coolant is good for 5 years. I figure coolant is more sensitive to time than miles per se.

I changed the factory fill orange G05 HOAT in my 2012 Ram last year when I hit the 5 year mark. I had 46K miles on the truck at that time. I want this truck to last and the price of Zerex G05 at AAP after discount code (when not on some lousy $2 off a gallon sale) isn't prohibitive IMO. I did not do any analysis on my used coolant.

I found the Mopar HOAT MS-9769 pricing to be significantly higher than Zerex G05 so I went with Zerex. It's a light gold / yellow dyed coolant but also MS-9769.

Personally I think hot weather driving in Texas beats up coolant chemistry worse / faster than cold weather driving in more northern climates. The good old Arrehnius equation.

Valvoline told me the life of coolant in the bottle is also 5 years.

It's a good idea to check the date code through your smartphone when picking up coolant in store.

The PI sheet for Zerex G05 shows a shelf life of 3 years.

So I always check the date code and I don't stock up too early.

I notice the thermostat starts getting laggy after 5 years or so. Gets slow to warm up.

Every 5 years and you won’t have problems.


If you want the job done right......do it yourself.

IMO it is best to treat the coolant life expectancy claims like the manufacturers treat their new car warranties - xx miles/x years, whichever comes first. So if the coolant sees its 5th birthday before it sees its 100,000th mile, change it.

Allowing it to go beyond 5 years in order to reach the 100K mile mark is a recipe for disaster IMO, especially considering the severe operating environment your geographical location imposes.

(My position on this subject was recently bolstered by personal experience with factory fill Mopar HOAT coolant that was allowed to go beyond the 5 year mark even though it had not yet been in service 100K miles. There were clumps of brown goo left behind in the overflow tank and what looked like sand particles filtered out of the drained coolant when transferring from drain pan to collection jug.)

Don't forget that coolant also lubricates the Water Pump etc. So the additives need to be replenished, etc. I agree about the heat being detrimental!

Where does it show the shelf life?

For me 5 years is a dream, because of the previous owner's neglect the coolant starts to turn brown after a few months on my Escort .

To Onetor and others:

I also believed in lubricating the water pump's bearings as an obvious necessity but was told the designs of modern water pumps is such that the bearings are isolated and coolant (or any lube you put into coolant) never touches them.

Lubricating them is impossible, they implied.

I grew up adding water pump lube to anything which had one.......I wonder if both old and new designs exist.

Which parts are lubricated by the coolant? The water pump bearings are actually protected from the coolant by seals. Once the seal deteriorates and is breached by the coolant the bearings will destruct in short order.

Correct. The pump bearings are behind a seal.

Wait till you get some of that lubricating coolant on any accessory drives like we have in our service vans. If the tensioners and/or idlers get any real penetration by the coolant it's time for replacement in short order.
