ok first off i am kinda new to the hole rotory thing. i have had no luck with the 1st one i owned and that was a 85 gsl-se. motor locked up on me. now the 2nd one i have is running nice and smooth, got this one a little over a month ago its a 89 gtu with about 125,000 miles on it. every thing is pretty clean under the hood. just replaced the water pump on it and have two questions for you guys. (if you dont mind) first one is how to bleed the air out of the cooling system. the book dont say a word on it. and second how do i pull trouble codes from it. the check engine light is on and as soon as i touch the gas the light goes out, let off it the check engine light come back on. why is it that this is going on? then after filling the cooling system up the low coolant light keeps comin on and that buzzer is drivin me nuts while i am trying to find out if it is leaking coolant, or if the water seals are bad i dont know. so how would i tell if the water seals are bad in my motor. i read about the bubble test but dont think that is a very good test. but is there a tool i can rent to pressure test the cooling system? thanks for any and all help
