Hey I have a 2wd 93 hilux with a worked 253 in it. To keep it cool I am running a davies craig electric water pump and I bought a alloy 2 pass radiator for a hotrod from ian boettchers motorsport and welded custom brackets on it. im running twin 10" thermos on the outside. I can idle in the shed with the doors closed and the temp wont budge past 90. Hope this helps
