Engine in or out of the vehicle?
It sounds like you're dealing with a California vehicle if the left side
header is separate from the heat exchanger. So, if the engine's still in
the vehicle (best case) get a fairly stout dowel and slide it INTO the
header. You don't use the dowel just as a big lever to try and rip the
header from the head, but you use it as a lever to get a little movement -
up and down - on the header while also pulling straight down from below.
You jiggle a little, pull, jiggle a little more, pull, and so forth. Having
a friend to help here is very beneficial. (A friend that'll help is one of
the best tools you can have.) If the engine's out of the vehicle and just
sitting on a dolly or block the drill is the same, though you end up rocking
the entire block and also can't get as good of a downward "pull."
As far as removing the fan goes, a friend who'll help is, again, very
beneficial. I've had my wife grab the flywheel (engine out, 'natch) with
thick gloves while I wrench on the bolts. She can't really hold the
flywheel against my torque but it's sufficient resistance that I usually can
get the bolts started reversing. Using a ratchet and then hitting the
handle of the ratchet with a sharp blow will usually "shock" the bolt enough
to turn a bit, even if she can't hold the flywheel entirely still. However,
I now use a flywheel lock (~$10 tool) for this exercise.
