I have a TBI 401 in my CJ-7. Motor has been in it for 8 years.
Last setup that worked was a Be Cool aluminum radiator, stock flex fan that had been trimmed to fit, a mediochre shroud I made and a cheap 16" electric pusher.
Now I am using (2) 16" fans, pusher and puller because I modified engine, frame and body placement and there is no longer room for the mechanical fan.
I have been wheelin on 80-90 degree days under load at 220-230 degrees. I used to keep it under 210 with the old setup.
Should I:
A. Buy a better 16" electric puller fan and replace the cheapo? $150-250 ?
B. Cut holes in the hood and install louvered vents? $50 ?
C. Buy a 4 core copper radiator and replace the aluminum unit? $300 ? Maybe cheaper cause I could sell the aluminum rad.
D. Buy a 4 cylinder and complain about power? Ha! Ha! No Way!
