Compression loss, a cracked or warped head, coolant in a cylinder, damaged valve seats, or severe overheating can require a replacement casting. Injector, piston, liner, deck, cooling-system, timing, and head-gasket failure causes must still be inspected.
D722 heads vary by engine specification and equipment installation. Match the engine serial and spec code, casting, injector and glow-plug locations, coolant passages, valve arrangement, and all three references.

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.
Model, production date, serial number, electrical or fuel-system version, dimensions, installed options, and previous repairs can affect fitment. Compare the original part and application information before purchase.
Frequently Asked Questions
Q: Does a new head fix the cause of overheating? A: No. Radiator flow, fan and belt, pump, thermostat, injection, block deck, and the original failure must be checked.
Q: Can I order by D722 name alone? A: No. Use the engine serial, specification, casting, and original head reference to confirm the correct revision.
Q: How do I confirm fitment before ordering? A: Match the original reference number where available, then compare the removed part, dimensions, connections, mounting details, model, serial or production information, and package photos.
Q: Is this an original-equipment part? A: No. This is a new aftermarket part. Brand names and reference numbers are used only to identify compatible applications.
