ok great i will look into that. if anything i will just save up and do both the thermostat and heater core at the same time. cause knowing the guy who owned this previously and how i've seen he's taken care of this blazer so far, it's never been touched. by the way my rant for the day. how dumb are people when it comes to taking care of cars in general. i just had to drop 400 on a complete brake job all around. i meanevery piece of the brake system plus inner and outer bearings. and come to find out while doing the brake job they must have had to cut out a stuck wheel seal. and they cut the front spindle. errrrr i hate dumb people
lol sry for the rant
