International Harvester / Farmall B Radiator Cap

FAST SHIPPING: Same-day Shipping for most orders placed during business hours.

If you are servicing or replacing the radiator on your Farmall B tractor, be sure and check all of the cooling system hoses. Hoses that are hard, brittle or cracked may need to be replaced. If they begin leaking they can shoot a hair-sized stream of hot antifreeze onto electrical parts and cause engine misfiring. It's good to change the hose clamps too since dirt and grit can make them hard to properly torque. Also make sure and purchase the correct hose size. A hose that is too big or too small will only cause problems at a later date.
