A good spraying with Purple stuff and a pressure wash once a year usually fixes it. Depends on your driving habits and if you don't put too much oil in the crankcase. I put in one less quart then the book calls for and haven't had to clean my rads for over 30K miles.

Side rads also need to be cleaned periodically, but they're easier to get to.

Your advice is very good. I might however caution giving advice about a pressure washer. I went against advice and used my pressure washer with one of the lower pressure jets in it. I kept it away from the radiator as much as possible. I only did a small area to test what would happen and luckily only had to straighten a small area of fins on the radiator. Pressure washers can bend the fins together keeping air from flowing through the unit. They are not fun to have to straighten. I think when you said pressure wash you might have meant with a garden hose and nozzle. The actual high pressure washers can cause damage as I will attest.

Pullers don't sell. And as others have pointed out, FRED aren't being made much anymore. I think for future resale those two factors should weigh pretty heavily.

In a given medium length, there are gassers, Freds, and DPs. This is also their $ order.
I see it as a buyers market for Freds.
