Bought a car at auction to give to my 16 year old. We replaced radiator, front bumper and fenders..

Location

Where does the rubber hose connected to the aluminum on the right with the black and blue screw driver stuck in it connect to? Not the hose nearest to the yellow windshield fluid cap.

Facing car from front the line nearest the left fender. the right line
What does this rubber hose on this aluminum hose on the right connect to?
It leaks coolant, I don't remember removing it to install the new part but there was no leak before.

Could this also cause a p0073 sensor reading 185? It wasn't on before
Thank You

Have you checked the hoses to and from the washer fluid heater? That's the only thing with coolant on that side of the car. The tubes also look like the correct size.

The heater itself is inside the reservoir. Look for a round plastic lid with 2 tubes coming out the top of the reservoir tank, close to where the filler neck meets the tank. You may have to remove the L headlight to get to it.

See this thread which shows where the hoses attach.

As Slammer mentioned... It leads to the side of the washer tank.
