P700 Small And Short Vent Hose???

[PolkaJoe]

I'm adding this here because my original post in a different thread led to this question.

I was installing a new Trail Armor kit on my machine and came across a "vent hose" which I have no idea what it's purpose is. I believe it is off of the oil pump (I could be wrong), it comes out and makes a sloping turn for the ground. It's very short and is obviously supposed to be some kind of vent or drain I guess. I had no idea it was there until I pulled the old plates, it was sitting right above, or on top of, the old center (metal) plate. Pressure relief? Temperature relief? .... I have no idea. It's stock ... my machine is only 5 months old.

Thanks in advance for any help, I appreciate it.

It's the drain tube for The water pump weep hole. The hole is designed to let a failing seal leak to the outside world rather than contaminate the engine oil (or vice versa) under worst case scenario. It MUST be vented and allowed to drain, though some put a catch bottle and keep an eye on it while routing a vent up high, as mud has been known to help eat the seal.

It also alerts you if the pump is going out with a puddle where you otherwise might not notice.

Makes sense, thank you DG Rider. I greatly appreciate you taking the time to respond and explain.

You're welcome. I'm sure there would be pressure changes it helps relieve as well.
