First....I know nothing about engines.
Indeed in my youth I burnt out 3 engines before I realised you had to oil in occassionally.
Senario... 1990 Sportrak EL
She's got 93,000 miles on her.
Water temp gauge raises about what was normal, but not fully over to H.
Expansion tank fills to overflowing, Rad empties out. (over 50 - 60 miles).
Radiator cap looks old.
Apart from that she's fine.
This is wife's pet what do I tell her??
Your help and advice much appreciated
