I just replaced the fan clutch. It had a horton ht550 but the updated one is the ht650.

Trying to wire a switch on my 98 ch613 to manually turn eng fan on. Any help please. Thanks

Hello. I'm new with Mack trucks. I have a 98 ch613 E7-427. It started pushing antifreeze out of overflow hose. I called Mack to question them. And they were good and full of answers, but the wrong ones I think. To this date I replaced the air compressor(per Mack). The water pump,water , pump housing(per Mack),fan clutch, thermostat and reservoir cap. When started it up it pushed about 3/4 gal of antifreeze out. Never went over 190 degrees. Ran it for about 2 1/2 hrr at 1600 rpms. Did bottle test and was getting some bubbles but not all the time. Should I go deeper? I pull a walking floor trailer and haul heavy mulch with it. Thanks in advance.
