FYI, be sure to check your radiator cap. I had to replace mine recently, as I noticed that my cooling system would not pull coolant from the overflow tank when the vehicle cooled down. Found that the top seal of the radiator cap had a crack in it and caused the issue. Replaced the radiator cap and all is working properly now.

 

I've seen balancers last indefinitely. I've also seen them damaged when people pull them incorrectly. When that happens, they may still look good, but fail down the road.

 

I replaced it last year but definitely will inspect it again thank you. Also, the overflow tank isn't it just for overflow ? How does it suck coolant back up if the overflow is low in coolant and the spout is up top near the rad cap??

 

For the time and effort I'm going to be putting into this I think I'm going to change that out to. the way that im going to attemp pulling it is with a rental tool that bolts on to the face of the balancer and pushes on the cam bolt

 

Well, if there is a leak in the hose or one of the fittings, it doesn't. If everything is good, it farts the air out of the cooling system which then vents to atmosphere. When the coolant in the radiator contracts as it cools, the air has been forced out so it slurps the coolant back. Just like siphoning gasoline out of the fuel tank. As long as there are no air leaks, it's a simple siphon effect. The first few times you drive the truck, it's forcing the air out. Eventually, once the air is purged, it's a closed system.

 

Cool. We'll I've definitely been neglecting it cause I don't keep the overflow topped up often lol ****...🤣

 

My air leak was the seal in top of the radiator cap. It was visibly cracked and you could see a gap in the gasket. Since I'm running the CSF 2969 all-aluminum radiator, I ordered the replacement CSF 4503 radiator cap via Rock Auto. That replacement radiator cap fixed my issue.

 

How do you like that rad? Would like to upgrade one day to a fully aluminum one. I heard you can pop in the v10 rads that are way bigger.

 

I've been very happy with it to-date. No issues with it except for the radiator cap recently. Unfortunately, the CSF 2969 radiator is hard to find these days, since CSF stopped making it. There are several other all-aluminum radiators available on eBay. You can read all about the CSF 2969 here - https://dodgeforum.com/forum/2nd-gen...-radiator.html

 

It's more important than you think. Air makes a fairly good insulator. Air bubbles in the cooling system don't cool that well. By purging the air, the radiator works better along with the heater core. The old non-pressurized systems had a void at the top. The low pressurized systems of the 50's were the same way. By the late 70's, it got to what we use now. The advantage is you can tell at a glance if you're low on coolant. So, yeah, it's fairly important.
