Frequently Asked Questions
What coolant reservoir tank fits a JCB 418 or 437 wheel loader?
Broken Tractor carries the JCB Reservoir Tank under part number 333/U7462, which fits the JCB 418 and 437 wheel loaders. These two models use a different tank than the smaller 400 series loaders, so match the 333/U7462 reference number to your old tank before ordering.
Which coolant expansion tank fits a JCB 411, 412S or 416 wheel loader?
The Coolant Expansion Tank under part number 331/34633 fits the JCB 411, 412S and 416 wheel loaders. The same tank also fits the 407ZX, 408ZX, 409 and 409ZX loaders, which makes it a common replacement across several 400 series machines.
What is the difference between the JCB coolant expansion tank with sensor and without sensor?
The Coolant Expansion Tank with Sensor, part number 334/G3689, has an integrated sensor port made for Tier 4 engine cooling systems. The Coolant Expansion Reservoir Tank with Cap, part number 334/G3688, is the version listed without a sensor. Both fit the JCB 406, 407 and 409 wheel loaders, so check whether your existing tank has a sensor port before choosing.
Which reservoir tank fits a JCB 409 wheel loader?
Three tanks we carry list the JCB 409: part numbers 331/34633, 334/G3688 and 334/G3689. The right one depends on your engine configuration and machine serial number, especially whether the loader has a Tier 4 engine that uses a sensor-equipped tank. Match the part number on your old tank, or call (800) 909-7060 and our parts team can help confirm fitment.
Does the JCB coolant reservoir tank come with a cap?
Only some do. The Coolant Expansion Reservoir Tank with Cap, part number 334/G3688, ships with the coolant reservoir cap included and fits the JCB 406, 407 and 409 wheel loaders. For other tanks, check the product listing to see whether a cap is included before ordering.
