Maybellene and 55 SHAKER,
Many thanks for your info- I have located a six blade fan here in Germany. It is a universal fit but I'm going to wait until the weather warms up and I can put a few more miles on my truck before deciding. Don't have an over heating problem that I know of. Two weeks ago we had a stretch of mild weather and I drove it every day. No problem at all. Only when I let it idle for 10 minutes or more. Then the radiator overflows. I think that's due to temperature expansion as opposed to over heating. Had the radiator professionaly cleaned and tested. It's like new. Also have a new waterpump and thermostat (180°).
Thanks Again,
Sam
