P1000 Engine water port

[oldgasser]

Hi There: I'm hoping a Honda tech guy can answer this. I just had the Clutch and heat upgrades done to my 2017 LE. Being an old school guy and having had the engine overheat once because the auto fan module failed I would like to add a manual temp gauge. I asked the service manager if there was a plugged water port in the head of the 1000 engine and he didn't know. Before I go looking I thought I would ask on this forum. If there is one what are the size and thread pitch? I'm not that impressed with the little 4 bar temp indicator and it prevents me from using the other functions when driving because temp is a critical item when driving.

Way to go calling me out like that. I'll check my manual and get back to ya.

arrow pointing at coolant temp sensor.
Might be able to find a metric 18mm tee fitting and fab something up that way. (don't quote me on the threads, just a guess)
Not sure if there are other ports.

I think you might be mistaken, believe that arrow is pointing to the bleed screw, witch has a 10mm head, so m6x1.25 maybe they make a sender that small. But the stock bolt is sealed with a copper washer. I don’t think it uses a o-ring to seal

You are correct, the arrow is pointing at the bleed screw, right next to it is the ECT. If you remove that, it will be a larger thread that should be easy to convert for either mechanical or electric temp sensor. I would take it a step further, and see if I could tap into the factor wiring and find a gauge that will work with those signals.

Thanks for the photos. Any idea what the size and thread pitch is of the drain plug? I should be able to get a temp sender that will replace the drain plug.

Hi There: Thanks for the reply. I may pull the existing temp sensor to get thread size and pitch and just replace the factory sensor with one for a gauge. I won't have any further use for the factory temp gauge unless there is some safety feature that causes computer to alter operating system without temp info.

I bet it will change something amount of fuel injected ,fan going on and off

Why can't all immigrants be like you? Wouldn't have to build the wall!

Yup, if it always thinks it is cold, it won't switch open/closed loop, it may even put the bike into limp mode.

On the other hand, if computer thinks it is overheating. It will constantly run the fan. I would have to check the service manual to see if it has other temp sensors. There might be one for the fan as well as the gauge.

Thank-you, Come again.

Yeah probably so. I guess the answer is probably to replace the drain plug with a gauge sensor.

Put a T in it and have both there

Koso makes inline temp gauges. Basically you cut the coolant hose coming from the engine to the radiator and put their tee in there then the temp gauge attaches to the other side of the tee. I have used these on several motorcycles and they work great. Just need to know the size of the coolant line
