Frequently Asked Questions
What is the Caterpillar C-12 Oil Cooler Lines kit 1348267 for?
The 1348267 covers oil cooler line components for the Caterpillar C-12 engine (serial numbers 9NS and 2KS). This is a related cooler line kit to the 1349807, covering complementary line connections in the oil cooling circuit to ensure the complete system can be serviced properly.
Which C-12 serial numbers are compatible with the 1348267?
This kit is designed for Caterpillar C-12 engines with serial number prefixes 9NS and 2KS. Confirm your serial prefix on the engine data plate before ordering. If you are unsure, reach out to Propel Parts for help verifying fitment.
Is this part compatible with both the 1348267 and 1349807 oil cooler kits?
These two kits are separate parts that may cover different line assemblies within the same C-12 oil cooling circuit. In many cases both kits may be needed for a complete oil cooler service job. Consult your Caterpillar C-12 service manual or contact Propel Parts to determine which kit ??? or both ??? applies to your repair.
Is this a high-quality aftermarket replacement?
Yes. This is a high-quality aftermarket kit that meets or exceeds OEM specifications for the C-12 engine. It provides accurate dimensional fit and reliable sealing performance to restore proper oil cooler line function.
What maintenance interval is recommended for oil cooler line inspection on the C-12?
Inspect oil cooler lines and their seals at every major service interval, or any time the cooling system is drained and refilled. Pay attention to early signs of weeping at connection points. Proactive replacement of seals and gaskets when the cooler is disturbed is always more economical than dealing with a failure later.
What other fluids should I change when servicing the C-12 oil cooler?
Any time the oil cooler circuit is opened, it is best practice to drain and refill both the engine oil and coolant, inspect and clean the oil cooler core for sludge or scale buildup, and replace all disturbed gaskets and O-rings. This ensures a clean, efficient cooling circuit after the repair.
Where can I find more engine gaskets and overhaul kits for the C-12?
For a full range of C-12 engine service parts including overhaul kits, gaskets, and seals, browse the Caterpillar inframe overhaul kits section at Propel Parts ??? designed to cover everything needed for a complete or partial C-12 engine rebuild.
This 1348267 Engine Gasket Kit is compatible with the following models:
2KS, 9NS, C-12 & more...
