We built an entire system to do this that included a hot water heater, and a catch tank, which recirculated hot water with detergent in it to clean out the system.  The pump came from a plumbing store.  We set it up with hoses that connected to the hose to the thermostat housing after removing the thermostat, and to the line coming back from the radiators.  Everything was mounted on a cart so we could role it under the car while it was up on the lift.

Dear  Friend, 

Thank you so much for the help and prompt answer!

Well I'll try this system as well, Will remove the thermostat from the thermostat housing, then put my pump outlet on the rubber hose that was connected to the thermostat housing and on the thermostat housing will install a hose that will drain this water in a bucket ( as a return )

Does that sound ok?! 

Sorry to be redundant, I'm not a mechanical and I want to be extra careful when doing this 

Thanks again and have a great week end

The longer dwell time under vacuum is purely a “belt and suspenders” method to test for any possible leaks; it is the perfect time to do it, especially if you had taken various parts of the cooling system apart.

It is nearly impossible to get all of the coolant out of these cars; there are just too many spots in the system where it can be trapped. On average, using the standard service procedures, you probably get 80-90% out at best. For car where we are forced to get everything out (e.g.: those that have suffered an intermix), we use an external pump system to force water or water/cleaner mixtures through the system for several cycles to push out the contaminated coolant before refilling.

Dear Friend

My car suffered from intermix and I notice that you mention that in this situation you put an external pump system to force water or water/cleaner mixtures through the system

My questions are:

1-) Where do you install this pump?

2-) May I use a bilge pump from a boat ( a rule type of pump with 1500 gph for example ) ?

3-) Is there on magic place where I install this pump and flush the whole system, or I have to go in parts? Like disconnect the hose from the thermostat nad put the pump on the hose and see the water being expelled from the metal tube OR the other way around ( pump IN on the Tube and Water OUT on the hose)

Then there is that smaller hose that goes in the pump housing ?! If I'm not mistaken?! should I flush that part of the system separated as well?

There is also the heater core on the passenger side, can I flush that part of the system with the pump?

Thanks
