To keep your CJ Jeep in optimal running condition, you should periodically check the fluids.

To keep your CJ Jeep in optimal running condition, you should periodically check the fluids. Preventing issues from arising is preferable to fixing the damage once it has occurred. Maintaining the fluids in your Jeep CJ can help extend the life of your Jeep. If you like to perform your own service on your Jeep, then you will need to know the specifications for fluid changes for your make and model of Jeep. When it comes to fluids, one size does not fit all. Jeep CJ fluid capacities can vary between year and model. The following chart will also allow you to easily access the information about CJ axle lubes and transfer case fluid capacities. The following are the fluid capacities and type, including AC system service information, fuel service information, and spark plug specifications. Your owner’s manual will also have this same information, but we’ve compiled it here for quick reference.
