Problem installing tank type block heater on a L553 skid steer with a Kabota V1902 engine. There is no where to install the heater hose on the water pump. Previous owner connected the hose by the thermostat housing. I tried that but cannot get the air out. Heater worked for a little while and quit. Seems to be air locked. To install the freeze plug type heater which it calls for it looks like I would have to pull the engine. Any advice?

well there is a radiator inline heater if you could get it on the lower radiator hose it could transfer heat to the block ( you would need to run it for a few hours). you might want to look into a battery heater blanket that will give you more amps to the starter also. I just ran into a problem with air on my m151a2 military jeep getting the air out after a water pump replacement and I drilled a 1/8 in. hole in the thermostat and problem solved. in hind sight I should have went 3/32 in. engine runs about 5 degrees cooler, but really no big deal
Thanks for the reply. The battery that's in the machine now must be oversize cause there isn't any room for a battery blanket. I was thinking of a air bleeder for a hot water heating system installed by the thermostat. Other alternative is to cut a large portion of the rear wall of the cab out to get at the freeze plug to install the OEM heater which I prefer not towell there is a radiator inline heater if you could get it on the lower radiator hose it could transfer heat to the block ( you would need to run it for a few hours). you might want to look into a battery heater blanket that will give you more amps to the starter also.

You should be able to get to the freeze plug with engine in. It will not be a fun job but looks do able. They say that is the best heater you can add. I have my engine out now and I am going to add one to mine. One thing is t he instructions say to put it in the frost plug behind the starter but I don't think it will fit. NH wants a small fortune for theirs but you can get one from NAPA or online for around 25 to 30 bucks. I bought one for the hise first but I could not get that one in as the lower hose was to shortThanks for the reply.

The info. I found the heater has to go in the freeze plug on the back side of the head. There is not enough room between the cylinder sleeves on the side of the engine to accept the heater. I can't even get my hand in between the cab and back side of the engine. That's why I'm trying to install a tank style heater. There was one on the machine when I bought it but it rusted out.You should be able to get to the freeze plug with engine in. It will not be a fun job but looks do able.

it might be different but when I put a block freeze plug type in a Perkins there was preferred freeze plug location but you could use others if need be. but maybe there is a internal clearance problem? but maybe ask the right question to the right person and you can find something out. I do know they want you to use a plug that sits low in the block so the fluid thermally flows by itself for more even heating.The info.

I have the Kabota V1902 engine which is supposed to have an internal clearance issue with the freeze plugs on the side of the engine. Think I'm still going to try the hydronic heating system bleeder when some more of the snow disappears so I can work on it. Thanks for trying to help. If it works I'll let you know.it might be different but when I put a block freeze plug type in a Perkins there was preferred freeze plug location but you could use others if need be. but maybe there is a internal clearance problem? but maybe ask the right question to the right person and you can find something out.

I have the same engine and the one I have said to mount in the front freeze plug farwest away from Radiator. I jave never heard of one in thecyl head. I looked at my Kubota tractor and the heater is mounted in a freeze plug on the engine block. This may be why they are called a block heater.
