;-) nice reading. Definitely good ideas on sawing off the metal screws coming off of the firewall, located close to the coolant flange...ask me how I know...
Anyhow, I humbly believe the coolant flange design, held on by two screws, works ok with metal flanges (cast aluminum or stronger should work well...no need for extra money being spent)...However, something tells me the bean counters f...up the engineers design intent...again...(I'm an engineer, if you can't tell already)...I sincerely doubt that an engineer would have designed such a critical plastic part like that...a third screw would have yielded much better results at about the same cost...
Summarizing...Done the metal flange...works well...would recommend...
