[Black Type II]

Hey guys love the forum and some of the sexy rides I see. I have a 93 L coupe and one of the problems I have is the car would run on normal temperatures but I would never get heat. I used to get heat when I first bought the car now its all ice cold air. I thought I didn't have coolant since I didn't see any when I looked in the radiator so I bought some coolant but after about 5 or 7 seconds of pouring it was topped off. So I turned the car and let it run. When temperatures reached normal level I put the heat on and I would still get cold air. I checked the radiator (didn't put the cap back on) 2 see if the coolant was flowing but it would steadily rise up and down and soon enuff you can tell that the coolant was steaming. Also the car's rpm level rapidly kept rising and declining. I'm not sure what it could be except maybe the water pump or the thermostat. Sorry for the long post but its winter in ny and its cold over here. Also I'm looking to install a remote starter so I would like 2 have heat by then and I'm also open 2 suggestions and reccommendations on the best remote starter (with keyless entry/alarm/ and paging) any help wpuld be greatly appreciated and sorry for the long post. Email me if possible as your response would reach me faster since I don't have a desktop and I'm using a cell phone but I will try my best 2 follow up and read everyones responses thanks again as I am finally out. Lol sowwy
