I recently flushed out the coolant in my VW. The previous shop I had taken the car to had used the incorrect coolant. They used prestone (yellowish green), when my VW requires G12 (pink). I drained all of the old fluid out, then flushed with water until it was clear. Then I refilled with the correct coolant.
When flushing out the system I noticed that the coolant was draining extremely slow. It took me nearly an entire day to get all of the old coolant out, flush the system with water, then refill with the correct coolant. Supposedly, I should have been able to fill the entire system with four gallons of coolant (50/50 mix), Ultimately, I was only able to fill the system with less than 2 liters!
To compound my problem, I didn't realize that I had also a blown head gasket/crack in my head. After taking my car to another shop, I now plan to replace the head gasket (and possibly the cylinder head) at home. That is another issue entirely.
I talked to a mechanic and asked why the coolant flush took so long to complete, and why I could only fill it with two liters. He said that he believed it was because the head gasket is blown, that MOST of the coolant is actually inside the engine block itself.
Here is my question: Do you believe the statement from the mechanic is plausible? And if so, how do I drain the coolant out of the engine block? Will it come out if I drain the oil?
I am preparing to learn as much as I can before attempting to fix my head gasket problem and want all of my bases covered so that I can do the best job possible. I believe I can safely do this if I have all of the information up front.
Thank you for considering my question.
have the same problem?
