I had a sniff around with the search and couldn't find much in the way of pitfalls of a coolant flush. Basically, I have a 7m in an ma61, and I want to do a full coolant system flush. Does anyone have a blow-by-blow guide on how to flush the coolant in an ma61? Maybe a scan of the workshop manual?
In addition to this, I'll also probably need to know about a coolant flush for an ma70 supra - seeing as that's my engine.
Are there any nasty little bits I need to watch out for that anyone knows of?
