should be two hoses going into the passanger side firewall. they go to the heater core. never flushed one though so wouldnt want to get wrong directions and make it harder than it needs to be.

 

I disconnected the two hoses attached to the passenger side of the water pump and flushed in both directions. I read a warning not to use too much water pressure. Flush until the drain water comes clear, and be careful not to get the OptiSpark wet.

Read a better description here.

 

alright ill try that and see if that fixes it... may be a while at least to this weekend till i try it...

 

alright i did this today and it worked verry well! i now have heat!! its so awsome haha but i did it a little differently. i disconnected the hoses as they went into the engine (the one on the top with the air blead) and (the one that goes under the engine) i can get pics of where they are at but it was really easy... easier than taking the hoses off closer to the heater core. however i did run into a problem because of he temperature and some plastic pieces...

when i removed the hose on the bottom of the engine he plastic coupling thing broke into two so i had to cut the metal/plastic part out and place a piece of pipe there to complete the tube but it worked verry well i ran water through it for about 3 min one way then changed directions for about a min than ran it back for about 3 more min and it started coming out cleaner so we hooked it back up started her up filled her back up with fluids and let the air blead out of the hose on top untill she started spitting out water...

then i ran her to the corner and back and she was pumping out verry warm air!

THANKS GUYS! THIS WAS A BIG HELP!!!
