Default No Power on Hills and Overheats Under Engine Load

I have a 1986 Toyota Camry LE 2.0 Automatic Transmission. It has 187,000 miles on it. My engine performance is ok on level roads even though it has a slight power sag on acceleration. And my temperature gauge is below half way. But when I was driving up on long mountain roads even with a 3 percent grade my car would go from 70 mph down to 40 mph. I downshift to 2 on the auto trans but even then it barely speeds up or just maintain 40 mph. Tachometer goes up to 5000 rpm. The temperature gauge goes up to 3/4 but not to the hot area. Transmission doesnít slip but when it shifts up on the grade itís very hard. When I go downgrade it cools back down quickly. I had the timing belt and water pump replaced along with the thermostat and radiator. And the radiator flows good. I donít know whether itís the nature of a 95hp engine or there is something definitely wrong. Engine does run great has good idle. I guess Iím just comparing newer camrys that could go up those grades faster than mine. Thanks for any advice.

Also Iím hoping I donít damage the engine at such high rpms. It sounds like its about to fly apart revving it like that.

The engine is not the most power one. On steep hills the car can have issues maintaining speed.

Temp gauge should remain steady. Do the radiator fans work?

Revs are OK as long as they stay below red line.

Any engine miss?

Yeah the fans work. Both of them. No engine misfire. I do notice that when I take off on level ground that the engine immediately sags on power a little then picks up speed. But itís only very slight

If lack of power on hills suggest looking into fuel issues.

The temp gauge moving up is not normal.

Check timing advance. Both of your problems can be caused by retarded timing.

. Ok. I have noticed are both fans supposed to be two speed fans? I noticed that when the engine is warmer than normal both still run at a slower speed. I thought that they usually run at a faster speed when the temperature exceeded a certain range.

yeah. If I crack open the heater setting the temperature gauge goes to normal pretty quickly. I checked engine timing and fuel pressure at a mechanic shop and everything is in specs. I donít know if the radiator fans are two speed or not. I also noticed that it has 3 fan relays. The number one and two fan relays are too hot to touch. Number 3 is cold. They are all metal covered relays
