Water pump, coolant ball or either hose leading to the coolant ball, heater hoses, you’ll need to take a look.

Just had my water pump replaced because it was leaking (@70k miles). The coolant was making its way on the accessory drive pulley and getting slung everywhere.

The repair was covered under CPO. Also had a timing belt kit installed while they were in there.

Did the same thing to mine at 53k under powertrain, vw covered pumps and both belts (coolant contamination), I paid for tensioner and rollers.

Looked at coolant ball and hoses they good and don't have any crust like where you would see leaking coolant , what heater hose are you taking about the one that goes to the heater core?

Yes, the heater hoses go through the firewall there, also keep in mind that if you have any kind of skid plate or under car dust shield the leak could be on the other side of the car and just coming out on the passenger side.

Solids in the system erode out the plastic elbows going into the fire wall. It will also erode out the plastic part of the oil cooler water jacket and make the o ring leak on the front of the engine. I wish I could figure out how to post pics of my eroded parts and the solids I got out of my system.

60,000 miles, the elbows and heater core went out.



70,000 miles the oil cooler eroded out,



Dug lots of this tuff out of the block,



80,000 miles the water pump went out.

Flush your systems!
