[Oletrucks] Oletrucks Digest, Vol 2, Issue 40

[mark]

if you have big radiator and it does fine at night its simply a matter of airflow.
Your fan is not pulling enough!

55TF camper ran hot if i pushed it... used water wetter, 100% distilled water, shroud.. etc. still ran hot.
removed flex fan and installed a same size fixed puller fan and now I can not make it run hot.

flex fan just couldnt pull enough air volume.

if you CAN run mechanical fan-do it. try a flex fan first(my TF is 7,000# camper with frontal area of a house!)
if flex fan still not work-then run 6 blade hard fan.

if you can only run electric-use a relay and a #8 wire to relay and big #8 from relay to fan.
also spend the bucks and get the highest CFM rated fan you can buy-$250 3,000cfm fan is cheap peace of mind over teh $100 kragen 1,000cfm fan.
