Thanks everybody

I did flushing in cool engine and cool water. Maybe this is the point.

Also, "laundry detergent", or "few drops dish detergent"? Means let detergent mixes with water, then start the engine until hot, hearter on, run for 10 mins? Is it safe to the cooling system ?

Experience of replacing the cooling seals is pretty much a nightmare.....

Thanks.
