i have a 66 cub and when it gets up to operating temperature it starts to spit out antifreeze out the overflow. can i use a pressure cap on this? also how far from the top should i fill this? thanks

You can use a low pressure cap if you want but it probably isn't necessary. The thermo-syphon cooling system will spit out the excess fluid and find it's own level which is usually about 1 1/2 - 2" below the neck opening. Generally, if the level is above the core tubes, you are probably OK. I think you'll find that if you leave it alone, it will seek it's level and stop spitting coolant. If you do go to a pressure cap, a 4 to 7# cap is about as much as your tractor will need.

In addition to BigDog's good advice,
Don't use a pressure cap on your 40 year old coolling system, pressurizing it will pinpoint each weak spot with a leak.

i did put a new radiator in about 13 years ago, thats still considered new in cub years right. ha ha. thanks for all your advice, i think i'll just leave it alone. also i just found a grease fitting for the rear pto, it was under a bracket, hopefully didn't ruin anything.

Don't bother to grease that fitting unless you are using the pto in a stationary mode such as a buzz saw. A single shot of grease once or twice a year is enough. There is another string dealing with this on the forum. The pto is splash lubed with oil from the differential when the tractor is in motion.
