I have a 61 220b, which has the 2.2 I6 (i believe its the M127) looks like this:
im looking to replace the water pump and thermostat, as its leaking and hasnt been changed in 25 years-ish. Is there a proper procedure to do it? I have the A/C, and I took a look and I can see I have many bolts to remove there. do I have to remove the A/C compressor completely? How does the fan come off?
Also, what size are the bolts that hold the Thermostat housing? Theres 4 of them and 2 have already snapped. this can't be fun....
