i have a 92 z28 with a 350 TPI and unless i am going down the highway it tries to overheat. i just had the thermostat changed and it is not leaking water. what is causing this and how do i fix it?

ill give some tips to help keep a cooler engine

get a cooler thermostat or drill a couple of small holes in the kind you already have

put a higher rated radiator cap on it keeps the coolent from bioling over becuase of the higher pressure

make sure your coolant is at the right level

put a lower temp fan switch on the car so the fan turns on sooner
