Why two thermostats in Nissan Xtrail? affects

Good night friends, I continue with the arrangements of my car Nissan Xtrail 2003, the mechanic told me that he found two thermostats in this engine that is 2500cc. And I commented that I would possibly suppress one. You can explain to me that it makes a thermostat and the reason why there are two in this engine and that it would happen if one suppresses it.

Thank you very much for the inconvenience.

Hello, I never seen two thermostats in an engine and it seems to me that one is left over, because the mission of a thermostat is to open the passage of water as the engine is heated. I don't know why he had two.

The mission of a thermostat is not only to open, but to maintain the normal temperature of operation of a vehicle if you had a diagram of the cooling site of that engine you could understand the why it carries 2, I know that it carries 2 and most likely it is that it finds some step, or water outlet where the radiator circulates even A dumping wear of the parts and an unreasonable job of the engine. When something is put into an engine, it is not for pleasure, it is reason, if it were for pleasure the thermostat in the countries of warm weather did not put them as the catalysts, in my country only a catalyst bring and an oxygen sensor but the North Americans bring 2 and up to 4 catalysts and no matter the number of cylinders because the QG18 engine of the year 2000 to 03 brings 4 catalysts. The one that bring more than one thermostat your engine is not for pleasure.

Hello, I will see I agree with Choto. You will see the issue is that there are vehicles that require an immediate heating system for the indoor heating of habitaculus, one of them Tine this mission opens to a tempera tura before the other thermostat in very cold climates is very efficient.

Pucha friend that you have given the time with your extray is not such a bad vehicle, but stop that you have to pay them all together, sorry, what the forists say the thermostat Substantial, they can be eliminated and do not try great damage, models with two thermostats are very scarce, they can be eliminated but usually I eliminate them only for tests if it improves or the failure is solved the replacement for new and already. If it is to prove you will not deteriorate the vehicle you have the test without fear, and then put whatever.
