Ok, you tell me what you think...I just returned from the dealership(for diff recall) and there is a huge coolant leak coming from the lower hose running to the radiator. It actually apears to be running from the temperature sensor that plugs into that hose from the top. I pulled the temp sensor and replaced the oring and leak got worse. And what I am seeing is that the sensor actually has some loosness when clicked in. My question is should I remove and replace the sensor? Is this a common problem with this model? are there any temporary remedies to this(ie. loctite or some kind of sealant)?
But when I start the truck you can see the coolant runs directly off both sides of sensor where it clicks in to place. Please help, any advise would be greatly appreciated.thanks

 

It must not be in place properly, the new o ring could be causing it feel like it is in but then in reality not set in. Try playing with it again.

 

its a BMW problem. you can't get that oring. We have already tried. You have to get the entire part.

Trust me we tried to fix ones like that and it dont work. BMW does that. instead of a simple gasket they make it so you have to put an entire part in it.

 

Thanks for your help Rovin4life, I found this thread last night as well to back up your point...

Could not find this particur brand o-ring but from dimension got it from my neighborhood hardward stor. Before with my old o-ring the sensor would click into place very loosely. Now I needed to push with force to pop the sensor in place. Sealed well! And the car runs great. Thanks for all your help!!!
