Ray.Fair enough.
I did a big service last year replaced the header tank and some pipes i drained the system and stuck some cleaner through i couldent believe the crud that came out.As a birthday preasent to my fourteen yer old mog i also stuck a couple of bottles of the water wetter in.Although i never hear my fan come on and my temp gauge is spot on there is a trmendous build up of heat
in the cockpit.After putting the water wetter in i can confirm that it was a total waste of money the temp gauge is exactly the same.The only thing i can say the excersise was worth it just to get the crap out of the system.

Welcome Ken as mentioned there is a wealth of knowledge on this forum Em
