Cleaning cooling system

Post by taylor6632 » Thu Jun 07, 2018 8:04 pm

Having recently done the head gasket on the 996, is was apparent that a lot of the waterways in the head were blinded with crud. Its back together and running sweet, starts off the key and on the 4/5th crank (luxury haha :D )

I want to give the cooling system a good clean before hay making this year to prevent similar happening again. Heard you can chuck a pot of bicarb in the rad and run it for a few days, then drain and flush with clean water/rad flush treatment, then fill up with AF and water mix. This won't do any harm will it? Heard the off the shelf stuff is no stronger than mouthwash.....

Hi. If its rusty I use white vinegar, I leave it in for a couple days then flush. Repeat if necessary. Use about 4 litres of it and the rest water.

Were you able to have a scratch around the water jackets while the head was off?
