The Double Order Catastrophe
My co-worker placed an order and wasn't sure it went through online. I later placed the same order thinking the previous order didn't go through. To my surprise both orders went through, and I needed to cancel one of the orders. I called and spoke with someone who instructed me someone would contact me about the situation. I was contacted by Misty and she said she would do her best to cancel one of the orders but not sure if she could because they were next day orders. A small tome later I received an email saying she was able to cancel one of the orders. Thank you to Misty and the entire Propel Parts Team. Greatly appreciated!! -
Everything fine, thank you. The only thing with which I had a problem in your Software, is that when I have more than 10 different items on the list, I can't scroll to the first ones. But besides that, I am very happy in going on with buying your parts.

Very helpful. Every question or request I had was answered quickly. I didn't have a parts book for my excavator but that was no problem for them. If you need parts for your Cat, give them a shot.

Frequently Asked Questions
What does the Caterpillar C-12 Oil Cooler Lines kit 1349807 cover?
The 1349807 covers the oil cooler line assembly for the Caterpillar C-12 engine with serial number prefixes 9NS and 2KS. These lines carry engine oil to and from the oil cooler where it is cooled before returning to lubricate critical engine components. Maintaining leak-free cooler lines is essential for stable oil temperature and engine health.
Which C-12 serial numbers is this kit compatible with?
This part is designed for Caterpillar C-12 engines with serial numbers beginning with 9NS or 2KS. If you are unsure of your serial number or need to confirm fitment, don't hesitate to reach out to Propel Parts for help verifying fitment.
Why do oil cooler lines fail on the Caterpillar C-12?
Oil cooler lines can develop leaks due to O-ring degradation, age-related hardening of seals, heat cycling fatigue in the lines, and corrosion. Any time the oil cooler is removed for service, the associated line seals and gaskets should be replaced as a preventive measure to avoid leaks after reassembly.
Is this a high-quality aftermarket replacement part?
Yes. This is a high-quality aftermarket oil cooler line kit that meets or exceeds OEM specifications for the C-12 engine. It provides the correct dimensions, materials, and sealing surfaces to restore factory-level oil flow and cooling performance.
What are the symptoms of a failing oil cooler line on the C-12?
Signs include visible oil leaks around the cooler line connections, oil level dropping faster than normal, oil contamination with coolant (milky oil), or elevated oil temperatures on the gauge. Any of these symptoms warrants immediate inspection of the oil cooling circuit.
What is the correct procedure for replacing oil cooler lines on a C-12?
Drain engine oil and coolant, disconnect the lines carefully, clean all mating surfaces, install new seals and gaskets, reconnect lines to the correct torque specifications, refill fluids, and run the engine to check for leaks. Always refer to the Caterpillar C-12 service manual for detailed procedure steps.
Are there more engine rebuild kits available for the Caterpillar C-12?
Yes. For more comprehensive C-12 engine service, Propel Parts carries a wide range of rebuild components. Check out the engine parts for heavy equipment category for overhaul kits, gaskets, bearings, and more for the C-12 and other CAT engine platforms.
