OC-3 crawler tractor

[felkatner1]

I have an )C-3 tractor (crawler) and have been working on the fan for the cooling. One question I have is it does not have a water pump. If I put an electric fan, will it cool the water and how will it circulate the water throughout the system. please respond

They have a thermosyphon cooling system and that is too why they had rather large hoses. DO NOT install a thermostat inline, it will screwup the water flow...;)

Greetings, felkatner1, and welcome to MTF. It looks like you have gotten an answer to your question, but I am going to copy this to another thread that may very well get you other info on your machine that you might want. It's going to be in the Big Tractor By Brand Section. (http://www.mytractorforum.com/forumdisplay.php?f=68)

If this happens to be the wrong section, it will get moved to the proper area.

Good luck, and be careful when you get in the other areas of this forum. You'll get tons of info and requests for pictures of you machine!

Enjoy.

Ditto to Thermsyphon system as others noted.
My mom still has Dad's OC-3 & HG and both were good crawlers.
