It covers draining the radiator, removing the soft plug (with the messy drain location shown honestly), fitting the heater bushing, a wrong-part mixup caught and fixed at the dealership, and torque/sealant details, ending with a real 30-45 minute time estimate. Best for owners planning this exact job themselves.
Posted by an owner-operator, Gaining Ground, documenting hands-on maintenance on their own CT5555 with some candid grumbling about dealership parts issues.
If you have all the right parts and know halfway what you're doing, it's about a 30 to 45 minute job, with cleanup and soft plug removal being the hardest parts.
The system holds 11 quarts, and draining it down to just below the soft plugs takes about two gallons, maybe a little more.
The owner iced a bunch of holes in the soft plug with an ice pick to weaken it, then used a pry bar to pop it out without pushing it in too far.
The bushing included in the kit did not fit, measuring one inch instead of the needed one inch and 3/8; the dealership swapped it for the correct size.
