Re: over heating
Hi Gerald,
FWIW:
In my humble opinion, using modern radiator flush kit liquid is as effective as washing your wife's dishes with used motor oil.
If I saw what you described with your Model A, I would try something very simple & very inexpensive first; i.e., I would try draining about 1/2 cup of your radiator coolant &:
1. To prevent too much soap suds, add not more than 1/2 cup of "Joy" liquid & allow your engine to run about 20 minutes "after" engine is at operating temperature.
2. Next, shut off engine, place a clean white sock attached to petcock, & drain coolant.
3. If coolant is dirty, or if debris is captured in sock, wait until engine is cool, add water & repeat steps 1 & 2 until coolant is clear.
You may have years of grease that came through the water pump & lodged in the cooling system -- Joy & warm water will loosen & clean grease just like it cleans margarine off of a plate.
Please let us know what happens.
Hope this helps.
