More questions--what floats? - Land Rovers Only

GKChesterton · 02-12-2006, 03:55 PM

In trying to figure out why expansion tank level sensor won't go off, I discovered this. Jumpered wires, light goes off. Pulled sensor out and pushed plunger up and sensor goes off. Hmmm. Placed sensor in glass of water and the plunger doesn't move up. It's lost its boyancey? Any one seen that? Was thinking of epoxying something to it but what would survive the temp and chemicals yet still float, any ideas? Thanks

Cork... that's what they use in gas gauges sometimes.. Don't know how it will do with heat/chemicals though, but gas is pretty strong.

Chris,
Floats do fail, they leak or become saturated hence they need to be replaced or in your case the switch has to be replaced if you want that light to go away.

Thanks. Good Idea yieldsign. Trying to avoid the 80$ for the new sensor with bubble gum and wire

. If I just jumpered it to make it go away it would always bother me that it wasn't working --some sort of psychological problem

Mechanics and parts deptments have an old saying," Pay me now or PAYEE me later". There is alot to be said for this.
If you don't fix it and while driving your coolant level drops and you take out a head gasket, then what will you do??
