It works too late Chevy radiator fan

I thank all your comments, they will be useful.
The thermostat does not have it, I do not know if necessary, I live in a very hot place, I have removed the thermostat for several Chevy´s, Corsa, and tornadoes and I have not had any problem with this point, and the water pump is new, and as the partner says, the fans enter direct at the high speed when they must work in low with motor heating without climate, and with climate the speed high.

It is not more for the time of the car, giving a maintenance lip siege to the radiator, since the early continues Closed.

Disconnect coils or CKP so that the car does not turn on, remove the cover of the water as the partner says, make it give you if there are bubbles or the water nivbel rises: the engine compression is going to the water and this recaliers the car (in addition to generating other problems) and the temperature sensor registers it and turns on the 2 fans: if this is so, if this mechanical problem is solved. The minimal packaging of fogged cylinder head, or tambourine.
OTA OPTION
The radiator can be clogged to refrigerate water efficiently, the temperature rises and generates the problem: make probe (clean) its radiator in an accredited radiator workshop

with respect to their comment about removing the thermostat from the vehicles: the water circulates freely, the water does not reach its operation temperature 90-100 degrees, the computer does not detect the temperature. Temperature at its optimal point, as the computer is never achieved, continues to apply extra gasoline by increasing consumption and generating collateral problems in the oxygen and canister sensor that must enter to burn this wasted gasoline reaching extreme temperatures that dramatically shorten its useful life and paqa replace it has a quite high cost

Look at the bulb that brings on the radiator also so activates the fan late I hope it serves you

There is no other is the thermostat, I bet you!
