Chemical Flush
« on: April 19, 2011, 13:41:50 »
Has anyone had experience with changing the antifreeze with a vacuum system to evacuate the radiator.  Any pros and cons in doing a chemical flush?

Had the antifreeze changed today,  The process worked well, no draining the block, disconnecting hoses or air pockets.

We flushed a customer's car with Forte cleaner recently with some interesting results.
Using an infr-red thermometer we saw 82 degrees coolant temp at the thermostat but 93 degrees (anyone know the secret key strokes for the degree symbol?) at the rear of the head before flushing and 82 and 83 respectively after. It should be noted that we also changed the water pump housing for a new one due to excessive pitting and this may have been causing cavitation.

The machine used was a BG CTL coolant transfusion machine. 

BG CT6
Large Capacity Coolant Transfusion System
The BG CT6 installs new 50/50 coolant into a large capacity vehicle’s cooling system while simultaneously removing the old, spent coolant. The BG CT6 pump can be operated remotely so there is no need to get off the vehicle or crawl from underneath it just to turn on the pump. The system has a 15-gallon coolant capacity designed to flush heavy truck and farm equipment. It is completely portable and can be used inside or outside the shop.

Unlike other systems, the BG CT6 has the ability of transfusing the coolant with or without running the engine. Most vehicles can be serviced with the engine off, thus preventing the common problem of continuous intermixing of new and used coolant due to the closing and opening of the thermostat. This process backflushes the vehicle’s cooling system, removing scale and debris not accessible when going with the normal direction of coolant flow.

Easy, just press the "Alt" key and whilst depressed, type "248" on the numeric keypad and the degree symbol will appear when you release the "Alt" key...

Hey, it works! thanks! I wonder why it's 248 and not 360?

Stick,

It has to do with the address on the code page for the keyboard and not the amount of degrees in a circle...    ;)
