Hi Antonio,

This may be cause by a intermittently stuck expansion valve. Your mechanic
should be able to tell from the pressure readings on the high and low
pressure side of the system.

Check the fuse for your auxiliary cooling fan. That was my problem after I
blew the crappy water pump they put in those things. It's a very
delicately-balanced system. Also check your fan clutch to insure it hasn't
crapped out.
