radiator
 

today i was lookign at my car and i saw that i had absolutely no rad fluid and ive been driving like this for a while im guessing since ive never touched it but yet my car never overheats,when i fill it up should i just fill the resevoir or both ,and isnt the fan suppose to turn when the cars on because mines not ???

the fan runs once the car reached operating temp (about 195 deg F if I remember right)

if the fluid is really low, fill the rad up AND the reservoir 1/2 way, then bleed the system (with the heater on full heat), then drive around till the fan comes on and completes 2 cycles, then let it all cool off and check the rad level again and add if necessary.

Use only Prestone + distilled water, or even better go and get Honda pre-mix coolant from the dealer.
