Hey John
I had the same problem as you. I just put in a brand new engine and decided
to go with a Hayden 16" electric fan. When I was in stop and go traffic
with the AC on I happened to look down at the gauge and notice it pegged
right at the "H"! Then I started to pull my 23' trailer and could never
keep it cool so out it came. I had too much invested in the new engine to
chance a melt-down. Ever since I put the old fan back on the gauge never
makes it past the half way mark. With the old fan you know it won't
overheat but with a performance water pump, coolant additive, and a extra
pusher fan can anyone say for sure that it won't overheat.
P.S. Anyone want to buy a Hayden #3710 16" fan, used only about a month?
Perfect for the V-6's.
