I put it on an A/C machine, and everything was fine.

Hi,

Two things to check. First, does the condenser fan (at radiator) turn on when the system is turned on? If it does, check the condenser in front of the radiator and make sure it isn't being blocked from air flow and isn't dirty. The condenser looks like another radiator. See pic below. If it is dirty, spray it off with a garden hose to clean dirt and debris.

Additionally, here is a link you may find of interest:

Let me know if this helps or if you have other questions.

Take care,

Joe
