Dads 01 has developed a coolant leak at almost 190k. Sure enough we check it out hoping it was the coolant hoses or a plug, but the block is cracked. Dad is very stumped over repairing the truck or getting a new one. What can be done to fix this? How long can you drive with the block cracked? Would this leave him stranded? quick help is appreciated as he would like to come to a decision on what to do.
