The temperature gauge of my Suzuki Khyber stays at the mark shown in the picture below. Sometimes, when in traffic jam, it climbs approx 5% further. Is this normal?
-The car has new original SGP thermostat valve.
-New water pump
-Coolant is ZIC
-Fan is auto.
-Cooling system metal pipes were changed
-Original Denso radiator cap
-Radiator was serviced a month or two ago. It has very minor seepage though, which doesn't reduce coolant.
-Engine was overhauled in Jan this year and head was surfaced.
One more thing which I want to know. You can see that the line at temperature gauge dial breaks a bit below H. What does that mean. Is it safe before that break line and dangerous afterwards?
