I suspect the coolant hasnt been replaced even once since i bought the car, and TASC is known to top it up with tap water. Of late the car has been heating up more than normal, though not overheating per se that makes this is more of a preventive maintenance thing for me.

The best way is to remove the bottom most hose of the radiator and then remove the cap of the radiator and put pressurised water in it. It shall thus remove all residue from the engine block as well.

BTW, I used ABRO radiator flush in my Scorpio at its 75K kms service for the first time. Then very carefully examined the drained coolant and also filtered it through a cloth. Not a single particle of any deposit or scale or sludge. I've been regularly replacing the coolant at every 20K kms.

I am going for the radiator flush at my 80K service tomorrow. I have already bought a can of Bardahl Fast Flush (300ml), printed price Rs 440/-, got it for Rs 400/- . Instructions on the can say that pour the contents in the coolant tank & idle the engine for 15 mins (alternatively you can drive the car for that duration). Then completely drain the coolant. Refill the tank with new coolant.

Bardahl website mentions the following for this product (Courtesy:HOEC BARDAHL INDIA LTD.)

"Radiator Fast Flush
Cleans the radiator


Removes harmful deposits on the radiator tubes that result from oxidations of coolant & corrosion of metal. Removes contaminants such as dirt, grease, oil or hard water deposits (scales). Improves efficiency of heat transfer from engine to radiator. Eliminates pre-ignition problems, engine oil degradation, thermal distortion of engine components."

Will share my experience with fellow members here post the radiator flush treatment.

I got my radiator flushed a couple of days back. Wurth radiator flush was used. It was pretty effective. The water became rust free after running about 15 litres of distilled water on a running engine. The temperature needle hovers at the 25% mark now.Cost about 350 bucks.

Because the Heating system works by passing air through a type of radiator in the dashboard in order to heat it. Turning it on helps flush out rust from that too.
