My motor temp is ok, but the air comming from my heating system is not really hot as it was normally, i assume that my heater rad is blocked partially (no liking and no fog in the winshield) , also, im not losing prestone, the thermostat as been change 3 time already by nissan original parts.
Im calling rad repair shop to get it unblocked and i got so many info, which one is the truth.
2 are saying that it is blocked by grease and they will unblock it with pressure hot water 2 other one says that it is calcaire (limestone), one is using acid and the other one is using costic stuff.when they says it is grease, they say that it is impossible to get calcaire since 80' and when it is calcaire, they say that there is no grease in the heater rad.
price are going from 40 to 160 $ can. i really dont know which one to trust.
