Hello,

My first post to the group, for what that is worth.

My alternator belt broke on my 2001 Elantra. I replaced the
pump (which needed to be replaced) as well as the belts. After the belt
broke I limped along for a few miles which may provide clues as well.

After installing the new pump the car now has fluctuating operating
temperature. It is normal when moving but rises when idling.

Additionally the A/C blows cold when I first start operating the car but
fairly quickly stops cooling.

I suspect that the broken belt may have caused some secondary damage. I
want to get in with a flashlight and do a visual inspection after the
sun goes down this evening, but I am seeking advice as to the likely
culprits in this scenario.

Perhaps it is just a coincidence that these new problem arose when they
did, but it seems unlikely.

Thanks.

As far as the overheating while idling - make sure that the fan kicks on
when it starts to heat up. Insure that the fan is connected (assuming
it is electrical)

Is the belt properly tightened? That would be the first thing I'd check. It
may be slipping and not turning the AC compressor enough at higher rpm.
Could be a defective water pump also that is causing belt slip. I wonder if
the thermostat was damaged when you drove the car hot and now it dos not
open/close properly especially at low flow rates at idle.

While checking the belts I considered the obvious and examined the
coolant level. It was very low. Filled up the radiator and both problems
went away.
