I just bought a 1990 nissan 240sx with 130k, automatic for 1900, it runs good, except the fan gets really loud on hard acceleration and one of the belts is squeaky on start up and sometimes at idle when it comes to a stop, body is really good condition and interior is somewhat nice yet needs some cleaning up.....

 

welcome to the forums, sounds like you need a new fan clutch

 

or electric fans, welcome to the forums.

 

Nice find. Get electric fans and a good thermostat controller for it and youre good.
