Drain System
1. Remove main fuse.
2. Remove access panel from right lower fairing.
NOTE
Leave pressure cap installed at this time.
3. See Figure 1-6. Remove rubber plug (3).
4. Remove pump/thermostat cover.
NOTE
Hose barb on the pump is fragile. Use caution when removing
coolant hose.
5. See Figure 1-8. Disconnect hose (5) from pump.
6. Drain and discard used coolant.
Using a squeeze bottle similar to a dishwashing liquid bottle
simplifies the procedure. Capacity is approximately 1.1 qt (1.0
L).
4. Fill system through filler neck until coolant is visible. Allow
coolant to bleed down for a few seconds and repeat.
5. Install main fuse.
6. Bleed cooling system.
a. Turn ignition switch ON. Turn run switch ON. Do not
start engine.
b. Turn throttle to greater than 50% and hold for at least
three seconds. Coolant pump and fans will start.
Release throttle.
c. As the pump runs, continue to add coolant until filler
neck remains topped off.
NOTE
Unlike operational mode, the pump and fans will run
indefinitely in bleed mode until ignition is turned OFF.
d. Turn ignition switch OFF. Pump and fans will stop.
NOTE
See Figure 1-9. Verify pressure cap is completely tightened.
Tab (2) must contact stop (1) for proper system operation.
7. Install pressure cap. Secure filler neck to retainer on
coolant bottle.
8. Fill coolant bottle to the cold fill line. Install rubber plug.
9. Start engine and check for leaks when hot.
NOTE
Coolant level in the coolant bottle typically rises when the
engine is at operating temperature. The level will return to the
"COLD" line when the system has cooled down.
10. Verify level in coolant bottle after system has cooled.
11. Install access panel.
1. Remove main fuse.

The manual says 1.1Qts of fluid. Does this include what ya put in the reservoir?
2016 Road Glide Ultra. First coolant change.
I'm running the pump and fans but that doesn't help it. I can feel the pump vibrating.
I was able to pour a little over a pint into the filler and it wouldn't bleed down anymore. I poured some into the reservoir, up to the cold line but I still have almost half a pint left.
I'm going to close it all up and run the bike up a little to warm it up, then let it cool off and check it again and add if I can.

I went back out and measured what I drained from the bike. 26oz. I measured what I've put in, 26oz.

Does the pressure cap screw all the way off or is it more like a half turn and it will pop off like a car?
