The question i have might be hardc to answer but if you know what im talking about i could use some help. On the back of some 350 heads there is a bolt that when removed coolant will come out. I am wondering if there is a bolt on the back of the 4.3 heads as well. I just need to find out what the problem is with this truck so i can fix it or start eliminating things.

 

Give some more feed back on the type of problems you are having and the guys will give you some ideas on how to go about fixing it.

good luck
