Drain Plug Question

[smeagol]

This was my first time to de-winterize and everything went well except I was not sure how many turns I should get on the drain plugs. One of them had a hard time getting started, and then after I got about two turns in, it felt like it was pretty tight. The other I got about three full turns before I felt like it was tight.

I may be forgetting from when I winterized, but I don't recall that the plugs were all the way in. Am I ok to have caught two or three threads? I did check for leaks and saw none.

I'd be curious to see responses as well. When I winterized two seasons ago, I left the plugs out in a ziploc bag on the sterring wheel. When I dewintereized last year, I had the same issue as you. I went all year without any problems. This past season when I winterized, I drained the water and put the plugs back in for the winter. My guess is they rusted a little bit.

They are NPT plugs so they are self tightening threads, mine always go about half way in and I've never had a problem.

This puts my mind at ease as well. Mine drain plugs are also my knock sensors on both sides. One seemed to screw in a little farther than the other, but no problems yet.

Excellent. That's what I was hoping... appreciate the feedback.

You guys are fine.

This time of year I only put my knock sensor in hand tight. Then at the end of the day I pull it out. You can see on the sensor that I'm only getting like 3 or 4 threads of engagement. I wondered about running a tap in the hole to clean any rust or whatever out of there. But recently a mechanic told me that he would never tighten the knock sensor up with any tool..... only hand tighten it.

That was news to me. I usually tighten it with some pliers for the summer, then remove it the same way in the fall.

I put my knock sensor in and out with a ratcheting box wrench. Prob. 10lbs. or just under wrist tight.
