Problem with my Sportage Diesel

Hello, friends, I am new in the forum and I want to expose my problem: I have a Kia Sportage Diesel 95, it is presenting a problem and it loses water from the radiator, it is not because I have to review it periodically.

It is also important to mention that I already checked the cylinder head and the water pump is new.

Well basically that is my problem, I hope someone can guide me to do, greetings and thanks in advance.

Is it with thermos fan or electrventilator?

They checked the cylinder head? These are very bad. The state of the radiator lid? The ideal would be a pond test in the refrigeration system

Hello, I think it's thermos fan, I'm not sure

Hello, first you could check the radiator lid to ensure that it is keeping the pressure of 7 to 15 lb, say in cap if it works well with the cold engine Removes the radiator plug and enclose the engine if you see air bubbles can be compression escape I hope it serves you
