I have the 95 Daytona 900 as some of you know and I'm trying to drain my coolant -- yes, without my service manual! So can anyone help me? I opened the reservoir cap, opened the rad cap and undid a couple of the lower hoses and a bunch of fluid came out. I tried to fill and flush the system by cleaning the reservoir and filling it with water (before I do a double Evans fill/flush) and running it until she got hot but I couldn't ever seem to get both sides of the system working.

It was hot enough for the rad to be steaming and I almost got to the red mark on the dial but it didn't seem to be taking any fluid from the reservoir.

Am I missing something like a bleed screw or an actual drain plug somewhere? Would it do me any good to cross post this as I know this is a "modular bike" and other models may be the same (e.g. Trophy, D12, etc).

Thanks in advance. :hammer:

Hopefully, I will be doing this in the near future. I have already drained the system. The waterpump is on the drivers side, below your clutch which has the bleeder screw on it. The waterpump has 2 8mm and one 10mm cap screws in it. The 10mm, left front bleeds the system. There is also a silver crankcase drain plug above, same side, I didn't get any liquid out when I removed it. The waterpump has a pipe exiting it toward the front. Below this pipe and above the exhaust is a rubber hose, about ?1/2"? with a hose clamp on it. Opening this one really lets the system drain. Thats the one I'd be sure to open up. The thermostat is IN the top hose coming off your radiator. I got a screw driver and worked it out of the hose. The manual suggests you put it in boiling water to test it. I pulled mine out and it was filthy, I haven't tested it yet but I plan on flushing with it out of the system. Ok, now to you question. The manual says,

From the Triumph Service Manual.

"Slowly add coolant to the system through the radiator filler till radiator is full. Start and let bike idle for short period of time to allow any air to be expelled from system. Stop engine and top up the coolant level as necessary. Fit the coolant pressure cap (NOTE that apparently the cap wasn't fit the first cycle). Check the expansion tank level and top up if necessary. Road test the bike to normal temperature, Stop, allow the engine to cool, and recheck the coolant level."

The Haynes says pretty much the same thing, except it says to fit the pressure cap the first time, make sure the reservoir is full, start engine, let idle 2/3 minutes, flick throttle open 3/4 times to 4K/5K rpm, stop the engine, let cool, fill radiator to filler neck."

The Thunderbird, Adventurer, and Legend TT have bleed screws on their thermostat housings, the Daytone doesn't, the thermostatis not in a housing, its in the hose.

looks like the answer is the air in the system is suppose to work its own way out with a couple warmup/top off cycles.
