anti freeze + door lock

hi,

ive just purchased a 1.8L diesel fiesta, 1991 (J).

i want to replace the anti frezze, but i am unsure about what type to use??

also

ive noticed that the drivers side door wont always lock first time & has a small gap (about 5mm) how easy is it to replace the lock mechcanism? or to move the lock mechcanism so that the door close's tighter?

thanks

you can use any good quality antifreeze(about 2lts)remove header tank hose and drain out.fill and this will circulate around engine when running.your door can be adjusted on the striker part with either an allen key or if fitted torks socket. if you have probs with lock,and it feels loose,it needs a new one.
