Can I drain my coolant with a broken Drain ****?
95 ls400. Searches only led me to people asking for the location of the 3rd draincock.
I am trying to do a radiator flush on and I got the front and drivers side drain **** to open and drain just fine.
The passenger side bolt that opens the draincock appears to have been broken off by a previous mechanic. Is there any way to drain the remaining coolant without having to drill out that bolt?
If I start the car will it push the old coolant into the radiator so that I can drain it from the front drain **** or water outlet pipe?
I still want to do a flush but dont know if this is possible without being able to drain everything from the system.

If the cooling system has been regularly maintained it is a minimal concern. If you've drained from the two locations, you are good. For all intents, I'd consider replacing the broken drain **** since you are in there. That way for future service this isn't an issue of getting the old coolant out.

I just decided to flush with water to dilute any remaining coolant before running the radiator flush chemicals.
Im waiting on the to cool now then Ill flush with water untill it comes out like I put it in.
Is it normal for the car to drip water when the heater is on like when the ac is on?
its coming from 2 holes in the middle of the car. It looks like it is supposed to be dripping from there but my hands are so dirty I cant tell if its pure water or not.
Also there is a black pipe that runs along the back wall of the engine bay, the wall nearest the cabin, and it is completely covered in condensation. Also normal?
