Mystery Hose on our Deere 110TLB

mtputney · Nov 18, 2014

We were getting ready to install a block heater on our Deere 110TLB when we discovered what looks like a mystery cooling hose going to the back of the tractor.

The hose starts on the left side of the engine block (facing forward) in the midsection of the block. This is where we think the heater should go. The hose runs all the way to the back of the tractor, to just in front of the back of the backhoe. It then connects to an identical hose which runs all the way back to the engine on the right side. It appears to enter the radiator at a connection just below the radiator cap.

Does anyone have any idea what this might be? I can upload pictures of that might help. Thanks in advance for any assistance.

I can't help with the hose, but I believe your TLB has a 4tnv88 engine, same as my Yanmar LX. Below are pictures of the ZeroStart block heater for that engine and where it should go.

Probably for a rear heater, does the hose get hot after running,

Yes, it gets hot. So I'm sure you are right.

Thanks.

So our tractor must have come set-up for a heater but without a cab

We still want to add the block heater, so I need to figure out what to do with the connection of this hose below the radiator cap.

Again, thanks.
