If you have a 2-row radiator, scrap it. Otherwise check flow rate before you spend the rent money on a new one.

Believe what you wish but that site is full of bad information IMO. It mentions using a 50/50 mixture of antifreeze to raise the boiling point. That is fine in a pressurized system but all of the antifreeze mfgs will tell you that their mixture needs to be pressurized to actually raise the boiling point over straight water.


Next, it mentions a lower radiator hose is leaking and suggests that the hose needs to be replaced. How does the advisor know whether the leak is at the radiator outlet pipe or the radiator connector?


It also mentions he thinks the coolant temperature should be 190°. It appears this is someone who has compiled a website based off of information from someone else and not from actual first-hand experience.


I will also tell you that a two-row radiator will cool a Model-A engine in average driving conditions. With most high-compression heads, you actually increase the water capacity because the chamber roof is lowered. Most bad reps that the two-tube radiators get is because the fins have detached from the tubes due to vibrations and work-hardening of the fins. The only advantage a three-row has in this scenario is there is additional fins to help dissipate the heat.
