Bobcat 753 Coolant Leak, expansion tank hose

[wdphillips]

A am a new member here and of course, with a problem. My Bobcat 753 has been a workhorse for me for 20 years with very few problems. I went into the barn where I keep my Bobcat to find a coolant on the floor. Further examination found the hose coming from the coolant expansion tank leaking from a pin hole sized leak. The hose is behind the expansion tank and I am assuming goes up to the radiator. The question I have is how to fix it. It would be nice to have a video or written repair manual but I have neither. Any help would be greatly appreciated.

There is both a repair and parts book in the manual thread for the 753 which should help you with some things, even if the serial numbers are out of range.
That should be a fairly easy thing to replace, unless it's positioned so that you have to remove the oil cooler and radiator to get to the clamp. Worst case scenario is you can cut the bad section out and sleeve it with a piece of tubing, provided you have the right size.

Hose goes from the tank up to the full neck of the radiator. Should just slide out. Believe it is 1/4”id hose. Bobcat used a cheap low pressure non braided hose I usually replace them with fuel line hose. Seems a little more durable just make sure when you route the hose you keep it away from the alternator belt and pulleys
