Machine models aren't listed on this page. Check part number H-504 against the machine's parts book, or send the model and serial number through the quote form so the parts team can confirm.
Match part number H-504 to the parts book entry for your machine or to the number on the old hose if it is still legible. If you can't confirm it either way, send the machine model and serial number through the quote form and the parts team will check it for you.
A heater hose is part of the engine cooling circuit. It carries hot coolant from the engine to the heating system and returns it, which is how the cab gets heat.
Common signs include cracks, soft or swollen spots, a hose that has gone hard or brittle, coolant stains or residue at the hose or its connections, and coolant loss with no other explanation. Follow the machine's service manual for inspection and replacement.
Have the part number (H-504), the machine model and serial number, and the quantity you need. If you are replacing an existing hose, keep the old one on hand to compare.
No. The store SKU (8310842) is how this item is tracked in our store. The part number is H-504, and that is the number to use when checking a parts book or confirming fitment.
