Bob,
Thanks for the advice!!
I'll get a thermostate
Hugh
: Add a thermostat in the upper radiator hose to compensate for the missing baffle. Model A parts suppliers offer a thermostat welded to a length of stainless steel pipe so that it will not flip over in the hose.
: If the overflow tube does not extend up to the top of the upper tank, then slide a length of rubber tubing onto its end to extend it.
: It is normal for some coolant to be pushed out of the overflow by the water pump, especially at higher engine rpm and when the coolant level is high. If the cooling system is functioning properly, the resultant coolant level will be above the tops of core tubes. The best rule of thumb is to maintain the level such that it is always above the tops of tubes and always 1" to 2" below the top of the upper tank / overflow tube opening. This leaves adequate volume for expansion of the coolant.
: Don't expect your Model A to months without adding coolant like modern cars do. the Model A has a non-pressurized system (vented to the atmosphere). So some coolant will be lost as hot vapor (steam) and some will be lost to evaporation. Frequently check and adjust the coolant level. It is not unusual that a pint to a quart of coolant is periodically necessary to maintain the leve in a Model A driven often.
