Okay guys, ive had my new to me 2002 series 78 troop carrier and I have a cooling issue. The good news is I know what it is. I have the 1HZ engine, but unfortunately the fan that connects to the fly wheel and shroud is missing. There is a cheap chinese electric fan bolted onto the radiator and its just not enough cooling at highway speeds. Under 50 mph running the AC im good, but on the highway I have to turn on the heat, and where I am (Panama) thats not alot of fun. My question is should I scrounge and look for the parts, or upgrade to a 4 row aluminum radiator with a dual electric fan set-up?

Finding the parts is the issue. From what im reading the 4 row dual fan cooling system might be an upgrade, just dont know :(
 
Might be worth investigating which Toyota's shared the same clutch fan maybe ?


A quick search showed China is selling copies ten a penny and personally i'm thinking its one of those parts so unlikely to fail that if it works its likely to last .

Motors Head Japan are also a very good supplier for genuine OEM parts, have used them a few times and found they are cheaper than Amayama
 
Is there a website or PDF with an exploded view of my truck with OEM part numbers?

So i installed the clutchfan yesterday, and even without a shroud it cools better than the dinky electric fan. Im going to build a shroud out of aluminum over the weekend :) such an awesomely simple truck!!!!
