So i had to change my coolant as i needed to drain it to replace a bunk hose. And lucky me now the heater doesnt work. So obviously the heater core got screwed. I heard something about pressure flushing the coolant system, im think when drained, it got pluged up, do you think a pressure flush would fix the problem, or am i looking at a new heater core?

 

Remove the heater hoses at the water pump and use a garden hose to flush towards the core. Go in one hose and then the other to flush it both ways. Keep the opti dry.

 

anyone got any good ideas of anyway to protect the opti? anyone ever guard it with foil or anything with success just while they worked?

 

also a question for shoebox, how did you join this forum in 1969? if my history serves me correct, the internet, and there forums werent around back then lol. But one way or another, you always seem to know your stuff, and your opinion and your website are much appreciated!
