CHEVROLET LUV MOTOR 4ZD1

Thanks to MDM for giving me a space. I am rookie at the Chevrolet Luv Pick Up with 4ZD1 engine; I have noticed that it is slow in the climbs, snoring in the sound of the engine and it is difficult to reach 100 km/h. I have also established that the engine fan is not appropriate and that the water temperature indicator barely reaches 1/8 of its range. I will appreciate your comments and help.

Hello, you will check the Turbo Union connections with Intercooler if this model rides Turbo because I think here in Europe is not marketed, greetings
