Hey folks,

Replaced the radiator, thermostat, and related hoses on my Disco 2. There is still a coolant leak happening -- the best can tell, it is coming from a line I can see beneath the car on the passenger side, below the thermostat, that touches / runs very closely with the wire for the coolant temp sensor. It appears to be going in to the oil filter? I'm having trouble finding out what this line is or what it does. Any help is appreciated.

 

Take pictures
I don’t recall any coolant lines under there except the one coming out of rad
maybe sounds like you have a leak above maybe dripping down there.

 

Here is the view from beneath my car. You can see the thermo straight in the middle. Bottom left is coolant temp sensor on the bottom of the radiator, and the lower radiator hose. The hose in between the two is what appears to be leaky to me. Although the green on the lower rad hose is throwing me off.



line in the middle of this, you can see it is soaked and the connection is slick

 

Check to see if the weep hole in the water pump is leaking.
Leaks from there can be constant or intermittent, and the coolant can end up in the area you are talking about.
And as red said pics will help. GOOD LUCK!

 

Thanks folks, pictures awaiting mod approval. I'll check out the water pump

 

I just wanted to bump this thread now that the pictures have been approved in case anyone can help me diagnose from here. Thanks!

 

When I did this, I disconnected the throttle body heater, because this is a common place for leaks. Unless you live in very cold climate, it's not needed anyway. Just pull the short hose at the throttle body and fit in a bolt. The other line goes to the coolant reservoir. Cut the line near the reservoir and bolt it. Also important is to replace the thin plastic tubing from the radiator to the coolant reservoir. When I pulled it, it broke into pieces like macaroni.
