Hi all

I have recently purchased a 1992 Non-turbo Mitsubishi RVR-X. After a couple of weeks everything seemed to be going ok. That is until i put it in for a service. The mechanics removed the radiator to clean it and flush it. 2 days later after getting it back I noticed a pool of coolant on the ground under the car. I took it straight back to the mechanics and they found leak in one of the hoses. I bought the car back home and let it sit in the garage overnight. I took it out today and once again there was coolant all over the ground. I looked under the car and found a drip coming from a small nozzle on the bottom of the radiator. I had noticed this before but didnt think anything of it. There is a knob just above it that I tried to tighten and got it to tighten a little bit more and it seemed to do the trick but now it is dripping again. Can anyone tell me what this little nozzle is and should it drip.

Any help would be appreciated.

you could try taking out the screw and check the thread on it ,clean out the hole and put back in,on mine theres a little rubber seal on end of plug
