1992 Nissan 300ZX

Engine Cooling problem
1992 Nissan 300ZX 6 cyl Manual

My nissan 300zx 92' non turbo, overheats after 30 minutes without ac and 15 with ac.

I already replace all the hoses, refrigerant sensors, switch temperature sensor, even the fan clutch( not the oem), but still overheating. Six months ago I replaced the thermostate. My radiator is new, no leaks.

The issue begins this summer, I live in a very hot city.

The only thing I haven't replace is the water pump. I already spent like 400 dlls. And I fear that changing the pump doesn't solve my problem.

What u suggest, im desperate.
