    m42 radiator troubles

    To those of you with an 24v swap and an m42 radiator, how did you bleed the system?

    Im having difficultys trying to bleed my s52 that i just added a new m42 radiator. I used a vac system to suck the coolant in ( so tenically i shouldnt even have to bleed it) but when i let it run the temp starting climbing and it was steaming pretty good. I took off the upper hose and got no coolant out but just steam. Is there a better way to do this or am i missing somthing?

      Raise the front, turn the heater on full blast, run it and squeeze the crap out of the hoses.

      Worked for me multiple times.

              This topic is beaten to death, searching should yield hours of threads to review.

              Raising the front or parking on an incline helps. I never got what was so troubling, run the engine, crack the bleeder screw and fill until bubbles stop coming out of it. Bleed screw - it serves its purpose.

                  dude, unless I'm an idiot (which sometimes i think so) there is not a bleeder screw on an s52 lol. i know there's one on an m20 yes, but not an s52.

                  also, i raised the front of the car and tried again and it hasn't gotten past half way on the gauge yet so it worked! :up:

                      Bleeder screw is on the radiator next to the cap.

                          Coolant quantity will be different for you, but this works perfectly and instantly every single time.

                              I never had an M20 so I didn't realize the confusion haha. Glad you got it sorted though (hopefully).
