Satisfied Customer.
I made my first purchase from Propel Parts last week. I was very happy with the response time and the delivery was fast, fast, fast! Also, the quality of the product is superb and at a great low price.
Keep up the great work!
Awesome and diligent support. Would definitely recommend
Steven & Propel Parts were a huge help! We were able to place a large order and get it shipped out same day to avoid a line down situation for a customer due to a lost component. The order was even submitted after the 3pm cutoff for same day shipments and we got it the next morning!
Amazing Help.
I don't know who I spoke with, but they were helpful. We will be buying those parts shortly.
rapid response!
A Delay Handled the Right Way
Honestly, if I were in Miami like my shipment was, I wouldn?t have been in a hurry to ship out either. I was frustrated at first ? delays cost me time on the job ? but Propel Parts stepped up.
Deb, Daniel and the team owned the mistake, kept the communication clear, and graciously refunded my shipping costs without making it a hassle. That kind of accountability is rare these days, and I genuinely appreciated how they handled it.
Things don?t always go perfectly, but these folks proved they?re more interested in doing right by their customers than just pushing parts out the door. Solid company, solid people.

P.S. Incredible quality on the pin as well. I had to do some custom modifying, and let?s just say the case hardening was ? well ? hard. Great Stuff! Thank you.
Great customer services, the best
Product Questions
Frequently Asked Questions
What does the Caterpillar 3116 Oil Cooler Lines Gasket Kit 1243686 include?
The 1243686 is a gasket kit for the oil cooler lines on the Caterpillar 3116 engine with serial number prefix 98Z. It provides the sealing components required to properly reseal the oil cooler line connections during service ??? allowing a complete reseal without having to source individual gaskets from multiple sources.
Which 3116 engine serial number prefix does the 1243686 fit?
This gasket kit is specifically designed for Caterpillar 3116 engines with the serial number prefix 98Z. Caterpillar used different prefix groups across production runs, so it is important to match the kit to your specific prefix. The 1002942 kit covers 2BK, 4TF, and 98Z prefixes, while the 1243686 may cover a more specific 98Z application. If you are unsure, reach out to Propel Parts for help verifying fitment.
Is this a high-quality aftermarket gasket kit?
Yes. The 1243686 gasket kit from Propel Parts is a premium aftermarket replacement that meets or exceeds OEM specifications for gasket material, compression properties, and dimensional accuracy. It is engineered to deliver reliable sealing performance in the 3116 engine's oil cooling circuit.
How do I know if the oil cooler line gaskets on my 3116 need replacing?
Common indicators include visible oil leaks at cooler line connection points, oil/coolant mixing (milky oil), unexplained drops in oil level, or coolant level dropping without a visible external leak. Any time the oil cooler is removed for cleaning or repair, replace all disturbed gaskets regardless of their apparent condition.
How difficult is it to replace the oil cooler line gaskets on the 3116?
This repair requires draining engine fluids, removing the oil cooler assembly, thoroughly cleaning all mating surfaces, and carefully installing the new gaskets before reassembly. An experienced diesel mechanic with the correct service manual and tools can complete this work in a well-equipped shop environment.
What other 3116 engine service should I consider at the same time?
When the oil cooler is removed for gasket replacement, it is an ideal time to inspect the oil cooler core for sludge or blockage, check oil and coolant for contamination, replace the engine oil and filter, inspect all accessible hoses and connections, and address any other known engine issues to maximize the value of the labor investment.
Where can I find more engine parts and overhaul kits for the Caterpillar 3116?
