Guys, we have the same ride pero hanggang 1/2 lang yung temp. nia. May mga suggestions ako maybe this will help.
1. Mag flushing ka sa engine and radiator, may nabibili na flushing fluid sa Handyman, DIY lang just follow the instruction on the bottle. Sa flushing this will remove the scales present inside the engine water jacket, lalo na kung di ka gumagamit ng coolant. Note, scales in the wall will reduced the heat transfer from the combustion chamber to cooling water and will increase the engine temp.
2. Check the main fan RPM, kung mabagal na then it will suck lesser air passing the core of the radiator, ang effect nito tataas yung engine temp. lalo na kung nasa traffic situation ka kasi yung suction effect ng fan gaay mahina na. Note may pagbabago kung moving na yung car mo, kasi may suction na from fan plus the air stream from the movement of the car.
3. Try mo rin fix some foam sa mga gaps between the condenser & radiator, para almost 100% ng air stream dadaan sa radiator core.
Yun lang po.
