i believe the fan is still working. didn't check. i still had lots of rad fluid, so i don't think my engine was over heating and i didn't drive long and it is colder here. i was going to try to replace the water pump seals and retorque the head first. see if that fixes it. just waitin for the parts. to retorque the head, should i loosen all bolts and torque or should i just loosen 1 bolt at a time and retorque?
