I can't comment about the coolant consumption as I'm not familiar with that
engine, but I can offer the following:
Don't use brute force on the spark plugs!!
You run the very risk of stripping or galling the cylinder heads.
Keep up a regiment of PB Blaster. Also, you could apply heat and sharp taps
to the plugs. Put the socket over the spark plug, use an extension and hit
it. You're looking to break the bond that had developed between the threads
and head. Don't hit them too hard. Be prudent. Do not give up. It can
take days or weeks to do this, but using brute force is never an option.
Once they break free, if resistance is felt when back them out - don't take
them out. Keep applying PB and allowing it to do it's job. Run the in and
out. You're looking to clear the threads at this point. Taking them out
will usually result in same type of galling that you would have experience
had you just busted them out.
It can be a tedious process, but it's the only way.
