Cooling System

might try looking on U TUBE ,

Cat site.

Don't forget the coolant additive...

Use the ELC (extended life) if appropriate for the 350 CAT. I've used it on my CAT 3176b....you might check Filter Barn( I get all my filters from them including the Racor desiccant air filter(the one that hiss's that keeps moisture out of your "air" system). Belts and some hoses are available thru Amazon(just got my Gates supertine belt from them). Anyways...it's a good days work so have at it! Good Luck...

I'm about to tackle the same project this Spring. I also could not find the coolant capacity, but in my Caterpillar book it stated that because the Manufacturers have different sized radiators installed, they cannot state the capacity for all applications. 5 to 8 gallons would be a good range to assume. And if you then get the concentrate, you're talking 1/2 of that, so probably 3-4 gallons of the actual coolant.

If you are going to run a cleaning solution through after you drain, you'll know the capacity based on that fill to flush the system in prep for the final draining and then coolant add.

Also, if you get the recommended Caterpillar (or Cat Approved) Extended Life Coolant (ELC) you don't need additives...it's all already in there. I got Rotella's version, which meets Cat ELC Standards. Fortunately I can get it for under $13/gallon through my son-in-law's trucking company shop since they buy it by the pallet load. Online it was running around $30 a gallon or $100 for a 5 gallon pail.
