Good to know, thanks!

Yep, they have been making coolant and other cooling system chemicals since 1995.

I would not stick with Mopar coolant. Mopar does not make their own coolant and they source it from various other coolant manufacturers depending on the vehicle and engine. They just take another brand's coolant(Xerex, Prestone,Fleetguard), slap Mopar on it and mark it up another 50% similar to how they sell a Cummins water pump for $200 yet you can buy the same part in the same box from Cummins for less than $75. Fleetguard(aka Cummins) makes a great coolant that that is much cheaper than the Mopar and is the same.

I'm pretty sure Fleetguard (aka Cummins) slaps a sticker on their coolant bottle as well.

Personally never buy Prestone anything! Radiator guy told me years ago Prestone kept him in business.

When I replace mine it will be the AMZ/OIL 5yr 150k Universal pre mixed at $14.45 a gallon.

As long as it meets the manufacturers specification it's acceptable to use. With todays coolant chemistry matched with distilled water you will never have a radiator issue do to the coolant.

I’d probably go fleetgard oat.
Hoses? I wouldn’t bother with unless you have a specific issue.
This isn’t 1967 anymore. Coolant hoses last a lot longer than 7 years.

Since back in the 80s-90s maintaining vehicles from the 60s-80s, I have yet to lose a coolant hose on anything under 15-20 years old. (Knocking on wood now)

^No kidding......
If Amsoil made bacon and maple syrup, you’d be 400lbs!

Xerex coolant from Oriellys and I use the OEM hoses. Mine have 122K on them and feel perfectly fine but I'm going to change them just for safety.
Truth be known, the hoses will out-last everything but I don't want to test that theory and break down in the middle of the dessert with my family.
