I was having a high temp issue with my 223, I flushed out the radiator and it clean and also the engine block and put a new 180 deg thermostat. It stopped at the "M" in temp but it it sat idling it would get hotter, so I removed the radiator cleaned it again and Im goingto install a 160 deg thermostat and I desided to take out the water pump to see what the vanes looked like and I found that the vans have broken loose. I read that this has happened to others thats why I looked. So I have my last car show and now my scramble to find another, Too my local NAPA and cross my fingers, The car shows on the 1st of Oct. OH BOY!
