I just pulled out the emissions and air pump , its running on 1 pulley and im hoping that the pulley is skipping , it over heats when still and am in process of buying double pulley the heating level goes over half then back to normal when i drive it!

 

yes, it's most likely because your belt is slipping.

 

thats something I need to look into, I've replaced the radiator, fan clutch, water pump and seals, thermostat, skid guard, and am now running about 80% water. It still overheats on hot days.

 

its actually probably not because your belt is slipping,
check fluid level and flush,
check thermostat
check pump it could be bad
does pump make any noise at all?
is there any brown residue as if water where leaking from front of pump?

check that stuff first before you assume the belt
