I've had my 54 plate Streetka for 18 months, recently I have noticed the fan seems to be kicking in alot after only short journeys usually when idling at the lights and the like. Checked the coolant level and it's fine, no obvious leaks or need to top up. Plugged in OBD tonight and the engine temp is running at 95 degrees as soon as the engine is turned on. Fan kicks in at 100 degrees which doesn't take long to reach..... Do Streetka's run on the hot side or do I need to investigate further? No error codes showed on OBD. Would a coolent flush make and difference?
