Frequently Asked Questions

What is the difference between JCB 334/G3688 and 334/G3689 coolant tanks?

JCB 334/G3688 is a coolant expansion reservoir tank that comes with a cap, while 334/G3689 is a coolant expansion tank with a sensor built for JCB Tier 4 engines. Both manage coolant overflow and expansion in the telehandler cooling system. If your telehandler has a Tier 4 Final engine, the sensor version is usually the one to look at.

How do I know if my JCB telehandler needs the coolant tank with sensor?

Your JCB telehandler needs the sensor tank (334/G3689) if it has a Tier 4 Final engine configuration. Many models, such as the 531-70, 535-95 and 540-170, appear on the fitment lists for both versions, so the model number alone may not settle it. Match the part number on your old tank or check your serial number, or call (800) 909-7060 and our parts team can confirm the right version.

Which coolant reservoir tank fits a JCB 538-70AG telehandler?

The Coolant Expansion Tank with Sensor for JCB Tier 4 Engines (334/G3689) lists the 538-70AG in its fitment, along with the 538-60AG, 536-95AG and 532-70AG. The cap-style tank (334/G3688) lists the standard 538-70 and 538-60 instead. Confirm your model and engine version before ordering.

Does the JCB telehandler coolant expansion tank come with a cap?

Yes, the Coolant Expansion Reservoir Tank for JCB Equipment (334/G3688) comes with a cap. That tank fits JCB telehandlers including the 506-23TC, 508-66TC, 509-23TC, 510-55TC, 526-56, 532-70, 536-70 and 540-200. For Tier 4 Final engines, Broken Tractor also carries the sensor-equipped tank, 334/G3689.

Which JCB loadall models does the coolant reservoir tank fit?

Broken Tractor carries coolant reservoir tanks that fit a wide range of JCB loadall models, including the 506-23TC, 509-45TC, 527-58, 531-70, 533-105, 535-140, 536-60DS, 538-60 and 540-180R. Some models, like the 535-125 and the AG versions, appear only on the sensor tank (334/G3689), while others like the 536-70 appear only on the cap-style tank (334/G3688). Because fitment can depend on model and engine version, match the part number from your existing tank.
