Re: What's With The Heat?
Ok,just keep it simple,what is the coolant temp.when you say it is overheating?If it is real hot 200-212 do the radiator drain test to check the flow rate.someone pipe in and give him the info,I forget what the figures are.

Re: What's With The Heat?
The drain and count method is as inaccurate as using a stick to do an alignment

Re: What's With The Heat?
Mitch and SteveB31 probably have it right. u need a nu radiator. The one thing that lots of folks overlook is the old radiators just wear out. The fins vibrate loose from the tubes and when that happens it quits transferring heat. The is ,was never none, solder holding the fins to the tubes. Just a factory press fit and over time the "press fit" gives out. Moral of story - you need a new radiator.
But just for funzies. Go to WalMart- buy a meat thermometer the round dial type with about a 4 to 6 inch stem. Leave the radiator cap off and insert the thermometer. Within a few minutes the thermometer will give you an accurate water temperature at the top of the radiator. |

YES! Get a meat thermometer and actually test the temperature of the water. It is just my opinion but I think that this should be one of the tools in everyone's Model A kit. Quails are okay but it sure is nice to actually know what the temperature of the engine is for sure. Before a new radiator. Triple check to make darn sure the timing is correct and the arm out of the back of the distributor is able to move fully to each side of the opening. If not fix that straight away and re-time. It could be grease from too much being put into the water pump causing issues if the above remedies don't work. In that case pull the radiator, plug the bottom outlet and put in one gallon of Simple Green undiluted. Plug the radiator inlet, cap and overflow tube and slosh it about several times a day for a few days. Drain and and flush and give it another go.

Re: What's With The Heat?
A Model A cooling system should hold more than that, unless you have a clogged or smaller 2 row radiator.... It should not be cooler down the center....be careful as you can slowly cook and hurt the motor

Re: What's With The Heat?
Much as I hate to say it...I think maybe the "new radiator" folks are right. It is a 3-row radiator since I can see 3 rows from the radiator car. Problem may be that all the ones I can see on both sides of the cap appear to be corroded or somehow closed and I'm assuming they should be open for water flow. Can't find an opening even with a long, very thin screwdriver tip.

Re: What's With The Heat?
Same problem here. Fixed it right up with a new radiator. Flushed it til I was blue and never helped.

Re: What's With The Heat?
Exhaust gasses in the coolant will tend to heat up the coolant even faster than it takes to gets the iron hot, it gurgles too. After checking with your new infrared gun get a price on a HC test kit before ordering a radiator.
