Want this question answered?
there is a petcock on the bottom of the radiator, passenger side. it is tricky to get to, but it can be done.
There is an O-ring on the petcock. You will need to replace the O-ring/petcock.
Just drain the rad at the petcock (little valve on bottom) & fill w/50/50 mix.
If it's a 5.4 you have to loosen the petcock on the radiator. There is also a drain valve on each side of the engine that you have to loosen to drain the system. Without this, you'll only get about half of the coolant out with the radiator only.
Answer:You want to see a picture of my petcock? I will show you mine if you show me yours. But my petcock is still a bit wild and not fully trained.........A petcock is a drain valve at the bottom of a radiator.
yes
There is not a heater valve in a WV Passat. Instead, coolant moves through the heater core at all times.
Typically there is a petcock valve on the lower left side of the radiator, unscrew the petcock to drain the radiator. On radiators without a petcock, you would remove the lower hose to drain the system. (Quite messy!)
The LONG end of the petcock valve is the indicator of the positioning of the valve. 6'oclock is MAIN 3'oclock is OFF 12'oclock is RESERVE
The Villager engine does not have a coolant bleed valve.
Drain the coolant from the petcock valve on the drivers side of the radiator using a hose to direct the flow of coolant to a container such as a gallon water jug. Remove the front bumper, headlights, radiator fan. Disconnect all coolant hoses. remove the intercooler. Disconnect the oil cooler from the readiator but leave the oil lines hooked up.
