I am looking at doing a complete cooling system flush and refill in my 1997 Dodge Ram 5.9 Magnum gas engine. 83,000 miles on vehicle. 20 qt. total capacity. 10 quarts of full strength.
History:
1st 9 years- Original Green every 3 years since new.
9-22 years, currently running Amsoil Polypropylene Glycol (low tox.)
Coolant system is in great shape!
- Hoses, thermostat, radiator, WP, up to date condition. I will be putting a new cap (15psi) on as a preventative maintenance due to being original. Original heater core, and I want to keep it that way... if you know what I mean!
It's getting crappy looking, especially in the reservoir. Thinking about just running the Amsoil again?
Any favorites for this engine? I can get Amsoil for ~30 gallon, but if it prevents me from having to do a heater core it is worth it!
My choices in order of preference:
1. Amsoil Polypropylene Glycol from preferred member
2. Zerex Original green from NAPA
3. Preston (all makes models) from WalMart
Amsoil is my #1 choice, because it has worked well for 13 years. I am also concerned about shocking the system with a different coolant and creating a leak.
I have to get full strength, as it is impossible to get all the water out of the system when doing a back flush with the garden hose (Preston kit). I am not opening engine plugs to drain the block or anything extraordinary on a 22 year old vehicle that is rusting away anyway.
Distilled water will be used as much as possible.
