98 vti(auto), Overheating

my car was heating up on stand still.
So i started off with the radiator cap, then thermostat valve,radiator servicing, then finally the head gasket. The head was faced. Now the car is fine even with AC.But going uphill(Murree etc),it crosses the middle mark.Honda,96-2000 has a pathetic "single naali" radiator. can that be the only reason? Anyone technical reply please?

From what i've come to know its really hot in Pakistan thses days. There's some facts you should knnow about the temperature guage.
1. The wide sweep usually marked wth white is the NORMAL OPERATING range of the guage. The vehicle is overheating ONLY when it reaches the end of this swpp marked in RED. This is not to say that the vehicle is running colder earlier.
2.Radiators have "shrouds" which encase the fan. The reason for his shroud is to prevent the fan from recylcing the hot air in the engine bay. Check for damage.
3. The half mark IS the normal operating temperature for the engine and these days if it does go a "bit" higher, its still okay as long as it does not dangerously hover near the extremity.Like i said its hot these days and ambient temperatures in the engine bay are much hotter than the already hot outside air. This is compunded by the fact that whilst going uphill, air flow is reduced and further compromised by the slipstreaming effect. Just to be on the safe side, check fan polarity and voltage.
4.Also give your A/f ratio and spark timing a once over, running too lean A/F ratio or an over advanced aprk timing usually causes this condition.
