Quick question. I have coolant dripping from a sensor on the bottom of the coolant expansion tank. I don't have time to pull the tank out and inspect it, but does anyone know hot the sensors mount in the tank? I'm wondering of they snap in or if one just need to be tightened if thsts possible?

 

I recall that it just threads in.

The sensor just pushes in and locks.

 

Thanks. Maybe I can check it in my hotel parking lot tomorrow evening.

 

my tank actually cracked at the fitting on the bottom, you might want to check that out. i had to pick up a new one at the junk yard

 

I've been travelling since last week. I'm hoping to be able to look at it this week, I just keep adding water/antifreeze as needed. I figure I wont have to change the antifreeze after a few weeks of that (kidding!)

 

It just snaps in.

My tank was leaking this last week, and I bought a new one. (links below)
I also did the hoses connecting to the tank as long as I was doing the tank. I had cracks around the nipple on the tank that connects the small hose to the thermostat housing. It was ridiculously easy to swap the expansion tank, I was timid since I failed at trying to swap the O2 sensor...and thought there might be a lot involved in the expansion tank. The tank just snaps right out, you don't need to unbolt anything. And the sensor, and sensor tube snaps right out as well. You most likely have a crack in your tank. But I would inspect it and find the crack first.

I would just buy a new tank, the hose, and caps.
