hi i have a 2004 kia sorento and if i leave the fan turned off for hot / cold air inside the vehicle my temperature gauge will go up to the normal temperature its supposed to go to at just below half but as soon as i turn on my fan it will push out hot air for me but then my temperature gauge starts to slowly go down until it hits the C on the gauge in which then it only pushes out lukewarm to almost cold air and then i have to turn the fan off again so that the gauge goes back up to just under half so i can get warm air coming through the vents what could this be?

okay thanks thats what i thought but wasnt sure as well it used to leak coolant but i put bars leak in the pellet one in the summer and then put coolant in and it didnt leak but now that its winter i bought another bottle of bars leak and put it in and then filled with coolant but its seams to be leaking a little bit but the reserve tank is pretty much full because after i put the second bottle of bars leak in it only took one 4 litre jug of coolant to fill the reserve tank to max
