Had the radiator replaced only around a month ago and i had to drain the system to add anti freeze which wasnt done at the time.
I found a white plug at the top right of the radiator which un screws to let water out. My question is should this be a metal one ? Is the plastic one only a packaging thing ?
Thanks
Mark
a lot of car parts are plastic now from caps to inlet manafolds due to production cost your cap should be fine .unless you can see any damage to it
