Overheating stock 94 ex coupe

I just bought a 94 coupe ex.
The temperature climbs up to 3/4 when stopping for too long at a red light after driving for a litle while, when i got the car the coolant was really low, i've since then refilled it and i cheked recently (yesterday) and it was still full, the cap on the yelow reservoir is not that tight could that be my problem ?

Do you hear your fan comming on when it starts to get hot? Try flushing out your cooling system and completly refilling it.

I'll do that tomorow morning and post back i'll also change my rad cap

make sure you got a thermostat. i've had this happen before when buying a new car.

rad cap, thermostat or fan relay....3 very common problems in hondas...or like me you can have a clogged rad... :(

I have a small leak running down the engine i think its where the thermostat is. It's on the firewall side of the engine on the driver side where the water pipes go into the engine theres some thorn cilycone leftovers hanging , i'm guessing i dont a ve a thermostat. Is it easy to instal ? and is there a guide somewhere ?

ya, buy a thermostat, remove the housing and old thermostat, put in new thermostat and re install the housing with a new gasket. (after of course you drain the coolant down so it doesnt splash everywhere when u take off the collant lines.)
