Radiator Tank?

Next to the engine on the passenger side of my truck, is a square tank. It is fed from the radiator. I can't find any reference to it in TM 9-801.

Is this a coolant storage tank? Does this serve any other purpose?

Sounds like it might be part of the "firepump" priming system

CCKW were not built with coolant surge tanks in other applications

hope this helps

It is the item pointed to in this picture:

Probably part of the primer system
Notice also the additional "tap" on top of the radiator tank
Without being able to examine the entire pump hook-up and how the pump itself was plumbed ,I can only guess that those "extra" items are indeed part of that system
Do you understand how your pump works especially in a "draft" situation ?

I have no clue how the pump works. The pump is being removed, so I am not sure if I should leave it there or take it out.

Thanks, to an old "Sage"

CCKWs did have a "Desert Cooling Kit"which did have an additional "coolant tank" mounted onto the firewall

However, Neil..this particular "tank" looks different

Hope this helps

Maybe I should keep it as a "Texas cooling kit".

Hi SpookyDad:

While I can't shed any light on what your extra tank is for, up here in the Great White North we have pump heating gear that runs off our rads and tank warming gear that basically routes the exhaust gases through extra tubing in the water tank... gets kinda cold up here in the winter and the water can get right stiff!

Don't imagine that happens in sunny Texas!
