Thats if your plastic overflow tank has not already cracked and started leaking.
They seem to be failing at this age.
They don't make 3liter coke bottles any more either! A 2liter bottle isn't enough to handle our "industrial" engine's overflow.Thats if your plastic overflow tank has not already cracked and started leaking.
Ford no longer makes the early style ones, could not find an OEM aftermarket one either, but eyeing the aluminum one Classic Diesel Designs sells.
CDD Remote Mount Coolant Reservoir
Replace your faded, cracked factory reservoir with our remote mount unit, comes with an o-ring sealed billet cap and mounting brackets, this allows flexible mounting options, with it commonly mounted off the radiator fan shroud mounts or core support to open more room up for cold air intakes and...classicdieseldesigns.com
The theory is you are less likely to have cooling system leaks. Such as radiator, heater core, head gasket, water pump, oil cooler, and hoses. So often on aging vehicles people put lesser caps on. In theory a 7# cap is pushing out 45% less on all those items.
Ya see! They ARE still making overflow tanks for our trucks!
