hey every one. i havent been on here in ages and its also been a while since ive fooled with a 4.3.

i just got a 00 blazer handed to me. ran it a little bit and it overheats.

i have coolant gushing out above the bell housing for the trans and its made its way into the oil as well.
its not the heater core and i cannot catch it flowing actively seems like it builds pressure then releases.

question: cant remember if the 4.3 has freeze out plugs on the rear of the block or not?
