JDcrawlers Messageboard

Can anyone tell me where the coolant sensor is located on the engine block on my JD 555G. The coolant temp. alarm goes off at different times for a short period of time. I have the Technical manual for this model but for the life of me I can't find the sensor.

Thanks for your time

I use cool gard 2 in my1983 450c problem is getting strips that aren't expired.When I start using cool gard 2 about 2 years ago the dealer told me just check it every 2 yrs: that it was good for six. Now they don't handle the test kit anymore because they don't sell enough of them before they expire...

Every once in a while I develop a rather loud squeal on the right side of the dozer. Could this come from the upper track roller or the bottom rollers. Or something between the track and rock guard. Is there anyway I can check the rollers or any suggestions. Seems like it happens just traveling,not ...

I have a 450c with tank heater I need to know how many drain plugs are in the block. I just finished replacing the fan rad. hoses. Started it up and burst the 5/8 hose tto the coolant heater tank. Took the lowest hose off and some nasty stuff came out, not much but enough that I want to do a flush. ...

I want to change the antifreeze in my 82 450c to the new extended cool gard II.Do I need to drain the block? And if I need to where are the freeze plugs located.The antifreeze in the machine is heavy duty diesel engine antifreeze now. It has an coolant tank heater. I thought maybe by taking the hose...

Is it necessary to change antifreeze every year (cavitation purpose) I only put about 30-50 hrs on a year. My manual states to change it every year.JD 450C

I need to find the bolts that hold the track plates on. Ineed about 24 . Also what kind of wrench do they need. The nuts are square and I can;'t get to them to tighten the loose ones.

Thanks

Has anyone heard about using antifreeze conditioner in diesel engines with wet sleeves.I talked to some mechanics about using the conditioner. Some have never heard of using and others say to use it. I guess one way or another it can't hurt.

when I ordered my technical manual from Deere for a 450 C it was on the list. Mine is expensive,about $230.00 bucks for the tech.manual for a 454c It tells me anything I wanted to know.

From what I can find out it is 1000 watts and even at 10 degrees I wait an hour and it starts right up...
