basically look at $1000.. for head & block work, new gasket, new bolts, water pump, radiator cap, thermostat etc etc
not too sure on the labour side tho
and $1000 for steering
wtf... theres something wrong there... what's wrong with your powersteering?
oh and waterpump line????
there isn't a water pump line as such... just the water galleries in the block & head
it seems your "mechanic" is talking about the water lines going "around" the block and feeding the heater core etc
unfortunately that is a pain to get to for repairs.. but you need to find out if that has a small hole from rusting out or if its just the gasket
do you know if it's leaking on the back of the thermostat housing or what?
can you possibly tell me exactly what location it is leaking?
did your car overheat? how badly?
