I have Nissan march 2000 A/T, 1000cc (ENGINE CG 1.0) which had a problem of radiator coolant boiled. Engine Oil & coolant didn’t not mix. Coolant gets back in the reservoir bottle. Temperature gauge showed below hot. Engine started very smoothly even at that hot temperature. I got head Gas kit changed two times but the problem of boiling coolant in the radiator could not resolve. Ultimately, I changed the engine of same specifications along with radiator but same problem of boiling coolant repeated after one year. I am really fed up. Could you please help me out to diagnose the problem relating to some hidden valve in the coolant circulation, ECU or anything else?
