Hi, my name is Haik, I am 32 years old and I am from Greece. My car is Alfa Romeo 1.6L twin spark.
The problem is that when I turn on the heating system the engine temperature begins gradually to
fall down the 90 degrees (celcius I assume) until 85-87 degrees. I assume that this happens because
the thermostat has possibly stuck open or closed I do not know. The question is first of all if what I described is the cause of the problem and how I can fix it by myself. The sole reason is because I like to learn and fix my car alone. Thank you for all and I am looking forward to your replay asap.

First, I would like to explain how the heater works. The heater has what is called a heater core. It is a small version of a radiator. Hot coolant enters the heater core and then a fan blows air through it causing the air to get hot. It is common for the heater to help cool the engine. However, it you feel the engine is cooling off too much, then there is a good chance that the thermostat is staying open.
