Hello guys,
am kinda new on site but get to read through anyway. I have a honda accord 4 cylinder 1999 model , i have noticed that the water level in my reservoir compartment keeps dropping and i have to refill back to the max level. I have checked the radiator for signs of a leak but none. what and i do and what might be the cause, my mechanic doesnt seem to have a clue except telling me to change to a double cell radiator.

@OP most cars have radiator fluid reservior tank which is marked "MIN" and "MAX" does your vehicle coolant fluid go below the "MIN" mark on the reservior tank?
Does your car experience overheat?

it tends to go towards that level bt i usually top it up to the max level, as for over heating issues lets just say that my fans dont come on automatically because it failed one day and the mechanic connected the directly, i have tried to get it fixed(changed the temperature switch) bt to no avail, last week i went to a mechanic to see if he could reverted the fans back to the factory setting bt he couldnt. so in a nut shell i have 2 issues
1- radiator leak
2-radiator fans permanently on(i knw its bad from what i have read on this forum)
