5 blade fan for PV? 444-544

Going to a 5 bladed fan may be more complicated than you think.

5 blades push more air than 4 if the length, width and pitch of the blades are all the same.

The incorrect 5 bladed fan may be worse than 4.

Why do you want more cooling?

I first thought that our '64 544 was getting hot under certain circumstances - hills, stop lights, etc.

After a 3 hour parade where the gauge went up and down, I found that the cat never really got hot - and I have a B20 engine. My gauge is sensitive.

Modern cars often have circuitry to keep the gauge steady - in some later Volvos , if your gauge shows hot, the car is REALLY hot.

A new fan may just be a band-aid. Find out how hot your car is really getting and find out why it is too hot.

One easy thing is to borrow an infra red gauge and look over your radiator. Your local FD might try this for you if they have an instrument

some cylinder heads have cooling tubes in them that can rot out and disrupt cooling.

If your car is really running hot, a better question might be - "Why is my B__ engine getting too hot" You might get several suggestions from brick boarders who have solved this problem.

Personally, in 50 years of driving, I have never had a problem, but in reading auto magazines all that time, I almost never seen a fan solve the problem, unless it was clutch fan that went bad.

The one thing that I have seen several times is some one removing the cap off a hot engine and blowing scalding water 20 feet on the air.

Once we had a Dodge van come into our fire house that could not be turned off, pulling the plug wires did not stop the engine - using a carbon Dioxide fire extinguisher in the air cleaner did stop it!
