I owned a 135 massey for years and it had a latch you just turned and raised the hood up. I didn't see one on my 98 Massey 231. Do you have to take all the bolts out around the hood then take it apart to get to radiator???
/ How to fill coolant on 1998 Massey 231 tractor????
That's a good question! Some clearly have a radiator cap and fuel filler cap on the hood, but others only have the fuel filler cap. My 241 has a flip door forward of the fuel filler cap that lets you get to the radiator cap.
Have you pulled the grill insert forward (like you're changing a headlight) to see if there's access to the radiator there?
