I used RTV sealant to prevent any leaks in the future. The old gasket has melted/deteriorated in some places. In my case, the problem was that the thermostat was stuck open.

If you have leakage around your reservoir, then could be that your reservoir is cracked, your coolant overheated and the pressure cap released some pressure/coolant, or maybe your bleed screw is not tight/leaking.

Try cleaning up the area and pinpointing where it's coming from.
Thanks man. I had been planning a good thorough cleaning of that area but just couldn't find the time. Also. Since my radiator light keeps coming on I have to keep refilling the radiator fluid. If I dont fix the problem soon I can just see the radiator fluid bill stacking up. Is it ok to just put water in my radiator? My car is always parked In the garage and I live in cali so it doesn't get below freezing. Thanks
