This is for a soon to be boosted truck, so hopefully this is the right forum. Truck is 2004 2500hd. Trying to make some room.

If were to put an inline/fill in the upper hose and delete the oem surge tank...

Just run the 2 hoses to the heater core and back? Cap the port on the radiator that goes to the surge tank? Nipple on the inline adapter to an overflow tank?

Thanks for any help!

 

I dont really recommend that as it can lead to some overheating problems. A better solution is a different shape coolant tank so you can retain the coolant reservoir functionality.

 

You could move the tank.

 

Or you could use something like this:

 

Yes just run heater hoses to the the heater core and back and just cap the port on the radiator that would normally go to the surge tank. Yes also to the inline radiator cap/housing, just run a hose from the nipple on the inline radiator cap housing to a overflow tank.

Def a lot of different ways to setup the cooling system for a turbo truck, Atomic makes a nice tank that will retain a expansion tank. I have ran it the way you mentioned it for a few years now though without issue even down here in the South Texas 100+ weather so either way will work.

 

I tied the two hoses that were on the tank together with a 1" x 1/2" adapter, installed an inline cap into the highest part of the upper radiator hose, and ran the filler's 3/8" hose to a coolant recovery tank. It's a completely functioning recovery system, meaning I have the level in the tank set at the cold level when it's cold, the tank fills a little when it's hot, and the radiator sucks the extra back when it cools down. I used a tank from a Durango or a Ram, I don't remember which one but they're the same. It is a tall rectangular tank.
I have been using this setup for only a couple of weeks, but I feel confident that it will function well when the weather warms up.

 

i did this a while ago, no overheating issues at all. just have to make sure the cap is the highest point which is easy on a truck.

 

OK, thanks for the info! I am going to give the inline cap/fill a try and see how it goes.

 

Been a while....

What inline neck are you using? The one i have doesnt seal with the cap I have (stant). Seems to vent fine, but it vents around the cap instead of to the overflow.

 

Mine's a Moroso. No overheating all summer.
