CAT 3126
Can someone that knows the answer help me please? Do the cat 3126’s have a thermostat on raw water side?

I used a 14 gallon tub and dumped 7 gallons of antifreeze in it and started the cold engine until it sucked it all in. Will this be sufficient? Or is there a y in the system that doesn’t allow all areas to get the antifreeze in and the water out?
 
See my response to your question in the 410 thread.
