Where does coolant go?
Stupid question and most of you are aware that I am an aircooled vw guy - no alternator!
Anyways I have a new dodge and there is an obvious coolant tank but where the heck is it on the 69 c10? I dont know if I am an idiot or if its missing. Also, it looks like I am missing a hose from my radiator, is this normal? God I feel stupid for asking ![]() |

Re: Where does coolant go?
Straight into the ra didy ator. You don't have an overflow tank. BTW, your pics didn't show up.

Re: Where does coolant go?
All we have are coolant reservoir tank overflow bottle. There should be a hose going from (just below) the radiator fill > into the overflow tank. You cannot link to images that are inside of your email account btw. There is no such thing as a stupid question.

Re: Where does coolant go?
Not sure why that tank is on the driver's side. A hose should run from the 1st pic to the 3rd. The bottle should be on the passenger side of truck though?
The middle pic, you are missing the heater hoses (manifold and water pump).

Re: Where does coolant go?
I can't tell you whether or not 69's had an overflow tank or not. I don't see how they could given the lack of room in that area. I see too many retrofits to believe that any of them had a stock overflow tank. My 67 just has a drip tube. The one pic shows the nipple that the drip tube attaches to. The other two pics show that your heater core isn't hooked up and that bottle is for windshield washer fluid.

As far as I know, none of the 67-72 trucks had an overflow tank from the factory as standard equipment. A tube should run down the back of the radiator tank from the barb shown in picture 1. In fact, there should be a clip part way down the passenger side tank on the radiator to retain the tube and, if I recall correctly, a small hole in the inner fender for the end of the tube to pass through. The tank on the driver side of the core support is the windshield washer tank which was placed in that location during the 1st few years of this body style. The radiator should be filled only within about 3 inches of the top to prevent overflow. The original radiators had this level marked on the tank. The hoses from the heater should run from the intake (5/8") and from the side of the water pump (3/4"). You don't need the heater as long as the intake and water pump ports are plugged.

Re: Where does coolant go?
Add an overflow tank to your passenger side fender or firewall. They allow the radiator to be full of water and this lack of air prevents corrosion. There are aftermarket tanks or you can find one in a wrecking yard...just make sure you have a cap and hose that pulls coolant (and expels air) to the bottom of said tank. The stock setup dumped directly on the ground on the passenger side of the rad.

AND, to answer your actual question, the coolant goes directly into the radiator. Edit: This is the only pic I can find, and it only shows the tube. Now that I look at the pic, I think the clip is on the side of the battery tray rather than the radiator. That is the original 4 row radiator on my 69... at least the tank is the original.

Besides Paint and wheels, my '67 is as stock as the day it came off the showroom... I don't have an overflow tank, I just have an overflow tube that runs down to the bottom of the radiator... in '67 nobody cared if a few (million) trucks leaked a little antifreeze on the ground...

Re: Where does coolant go?
They do if they overheat. Thus the name, overflow.

Re: Where does coolant go?
well, there's no worries there... the truck only gets started up every few weeks at the moment while I'm woking on my '96 and '97... Then I'll be putting brakes and new tires on her so she can be a garbage truck for awhile as I'll be working on the '69... then her day will come and she'll have an overflow tank then...
besides, it's not like the thing overflows every time it runs...

Re: Where does coolant go?
Maybe I'm just lucky. I've driven my truck with a 2800# cab-over camper all over the western half of the U.S. up steep mountain grades, in 100+ degree temps with the A/C on and with a boat in tow behind the camper and never had it overheat. Most overflow is the result of a radiator filled to the top when there is no overflow tank. That overflow is merely the result of coolant expansion. However, a properly maintained cooling system is essential.

Re: Where does coolant go?
I can't type all this out so I'll copy/paste.
http://auto.howstuffworks.com/how-do...r-cap-work.htm "a protective cap that’s actually a pressure valve and a tank on each side to catch the coolant fluid overflow." "When coolant fluid overheats, it expands, causing the fluid to become highly pressurized. When it enters the radiator, the pressure increases even more because it’s in an enclosed space. The radiator cap acts as a release valve set to open at the maximum pressure point. Usually this is set at a density of 15 pounds per square inch (psi). When the fluid pressure inside the radiator exceeds 15 psi, it forces the valve open, allowing heat to escape and excess coolant fluid to overflow into the tanks on either side of the radiator."
