when i replaced all of my belts i didnt replace the ac belt, because i dont have ac, now on other cars i know that this doesnt matter. but now i am having problems having to replace my crankshaft pulley constantly because the pin breaks off, could that be a reason?
also i had a heater valve way behind the head break, luckily i caught it before i blew my engine or something bad. but anyways question being i just capped off both of the lines, the one on the head and the one going into the firewall. was that a bad thing to do? i tried to get the replacement valve/pipes but the source i used was wrong and got all the wrong parts, oh well.
