coolant flush after hgf?

[Thomas. PLease.]

Hi there, my 2.6 had hgf, which has now been repaired hopefully. However, I've just removed the water pump to change it, and there is a coating of sludge inside the engine block. Its not too thick but there is a fiar bit there.

The engine hasn't been run for more than a minute or two since being in the car.

Also the rad is from a different car so is good and clean.

Whats the best thing to do? Give it a proper flush? If so what with and whats the best way to do it. Or just change the coolant again after it has had a proper run?

Thanks, Tom.

All I can say is the HG went in my Streetwise (Lovely K series), was flsuhed through with water and filled. They told me to run as normal and come back in 500-1000 miles and get it flushed and changed. There isnt a lot you can do with the sludge!

flush it with washing powder (cant remember if its bio or non bio) but cleans it out perfect
