Hi guys just fitted the lower temp thermostat mod at the weekend, I did this with the kit of 3 plates and the m60 80degree stat, so today I plugged in Hawkeye to monitor coolant temp. Radiator averaged around 65-75 degrees driving, engine upto around 97degrees, under load, I then got stuck in traffic for around 20 mins and temp peaked at 106-107degrees, is this roughly correct with an 80 degree stat? I've seen posts where people have said the car stays constant at around 90degrees. Is it possible I have a blockage somewhere?
