Frequently Asked Questions
How do I confirm fitment?
Perkins thermostat numbers have been superseded over time. Compare the existing thermostat and current parts reference for the exact engine build.
When should the engine thermostat be replaced?
Replacement makes sense when diagnosis confirms the original component is worn, damaged or electrically/mechanically failed and the rest of the related system checks out.
Is this an OEM part?
This listing is for a replacement part. Brand names and OE/reference numbers are used to identify fitment unless the listing specifically states that the item is genuine OEM.
