Hi guys,

I have got the knowledge of how to flush coolant from drain plug from this forum but according to youtube lots of people do SUPER flush which is flushing coolant in the heater core, engine block, radiator, etc.

Has anyone done SUPER flush? If so please let me know how to do it on V8Vantage MY07. If it is not necessary, I don't have to but I would like to know at least.

Thank you very much in advance!!!!

 

If you run the car till its at full operating temp with the heater in full max heat mode . Then shut the car off and drain. The coolant (be careful not to get burned by hot coolant ) then take a compressed air source and pressurize the system from the top by using a mcgyvered adaptor on the expansion tank you should blow 90% or more of the coolant out of the system.

 

Thank you very much for your answer.
I probably have to wait until the car got cool down and drain, correct? or is it better to drain when it's still hot?
I got an air compressor, can I use it and seal the gap between air compressor nozzle and reservoir opening by something OR do I have to have the adaptor you mentioned?
If I better have the adaptor, can you please let me know what size/model I need to get.
Looking forward to hearing!! Thank you!!

 

Has this worked for you in the past? I don't see how pressurizing the system would drain more coolant. If there's a pocket of water sitting at a low spot, pressurized or not, it's not going to move. Maybe if you could pressurize one side of the system, but you can't. If it's pressurized at the top of the system, it's pressurized at the bottom if you've drained the coolant.

@anasu98 I assume what you're referring to is the process of repeatedly flushing the coolant with clean water until it comes out clean. Unless your coolant is old or contaminated, I don't know that this would be necessary.

 

Thank you for your answer.
It's been about less than 2years, but I need to change the thermostat so I would like to flush the coolant at the same time.
When you repeatedly flushing, I guess I need to remove the thermostat for better flow?

 

The service interval is 5 years. But if you need to change the thermostat you can just drain and fill. This is the procedure instructed by the factory service manual.

 

Drain and refill, you can use distilled water and run it thru. Compressed air will just add air pockets and hamper for refill and bleeding of system. Just drain and change the thermostat, refill with the approved coolant/water mix for your climate.

 

Thank you for your answer.
I will just do that without compressed air then~!

 

Here's a video titled "superflush". I think it's just this author's term for his procedure, it's not an industry known term as far as I know. The procedure is to drain and fill with water, run the car, and repeat until the water is clear. Again, if you've changed coolant 2 years ago and you're updated on maintenance, there's no need to do this.

 

He needs to replace the dampers

I should have been more descriptive . With the drain plug removed and coolant gravity drained .
Insert compressed air gun into expansion tank cap opening , seal around air hose with whatever you can find , wet rags are good . Use air pressure to blow out coolant sitting in the block etc to the lowest spot ie the drain plug hole .
That better ?

 

No, still doesn't make sense. The air passage from the top of the tank to the drain plug is open. Air is just going to go from top to bottom, it's not going to push out any more water. I suppose the moving air may pick up some moisture as it flows around, but it's not going to be significant.

 

Yes, this is one of the videos I watched on Youtube. I will see what color of coolant comes out and decide if I have to use any Flush+ Cleaner as he did. Thanks a lot. Just checked the service history and it was 3years ago.
