And if it does where is it mounted it’s missing one and the only thing I can find is the tank for the windshield wiper fluid please help thank you

    On the off chance that you decide to add a post-retail coolant recuperation tank from NAPA or Carquest (smart thought) make certain to add an AC Delco 16 lb. shut framework radiator pressure cap. Any Chevrolet or GMC Dealer ought to have these

    Follow the rubber hose from the side of the radiator filler neck  and it goes to the coolant reservoir tank.....if it has one. Since 1965, are you expecting everything to still be on the car?

    65 has the old style motor. The coolant tank is the highest point of the radiator.. There is no flood tank so the abundance just spilled on the ground. No doubt, that was how it was. Coolant was modest. There is a little elastic hose that is by the coolant cap which let it spill out (as hot coolant extends) and cold coolant contracts down once more. It just releases this out once. ..furthermore, that is presently the appropriate level when it is cold. Try not to be neurotic and add coolant since it looks low. It actually should cover the blades which implies there is sufficient. At the point when balances are uncovered it would appear that Swiss cheddar, there is numerous little cylinders that are uncovered.

    '65 has the old style engine.  The coolant tank is the top of the radiator..  There is no overflow tank so the excess just dribbled on the ground. Yeah, that was the way it was. Coolant was cheap. There is a small rubber hose that is by the coolant cap which let it dribble out (as hot coolant expands) and cold coolant contracts back down again.  It only leaks this out once. ..and that is now the proper level when it is cold. Don't be paranoid and add coolant because it looks low.  It still should cover the fins which means there is enough.  When fins are exposed it looks like Swiss cheese, there is many little tubes that are uncovered.  Then you know you are LOW.  That is the original design.

    If you choose to add an aftermarket coolant recovery tank from NAPA or Carquest (good idea) be sure to add an AC Delco 16 lb. closed system radiator pressure cap. Any Chevrolet or GMC Dealer should have these.

    Not likely. Old cars did not have them, just a hose leading out and down so it would drain on the ground. Feel free to look for an aftermarket unit.

    Your '65 did not come with a "reservoir" tank - thru 1967 or '68 the windshield washer tank was snugged-up to the upper radiator hose on driver's side . then it was relocated to near the firewall on driver's side and a coolant recovery tank was mounted behind the grill in front of the radiator support crossmember on driver's side.  ADDED:  the terms "reservoir tank", "overflow tank" and "coolant recovery tank" are being used interchangeably - - - THEY ARE NOT THE SAME THING:

    Many cars had "reservoir tanks" instead of radiator header tanks due to low hood design, or the appearance of cross-flow radiators that did not have header tanks.  My '61 Thunderbird had a reservoir tank with pressure cap separate from the radiator due to the low hood . . . .'63 Corvettes and Avanti's introduced crossflow radiators with separate tanks with pressure cap.  The first "overflow tanks" did just that:   collected the overflow as the engine heated-up but the coolant did not return to the radiator as the engine cooled.  Didn't take them long to figure that if they made the connections air tight, the vacuum of the cooling engine would suck the coolant back into the radiator = coolant recovery system.

    Seriously?  You are capable of changing an engine, but you cannot figure out a coolant overflow tank?
