I'v alwaysed noticed the smell of coolant. Replaced the thermostat 6 months ago. All good for maybe a month or 2. It would try to overheat and I would open the hood and release the pressure in the overflow tank slowly. Close the hood and on my way for about a week or 2. I noticed coolant leaked out a few times. Maybe 4 or 5 times. Also, my heat takes awhile to heat up and same goes for the AC it takes awhile. Last night I went to play ball and didn't make it maybe 5 miles befor it tried to overheat. I pulled over poped the hood released the overflow and drove to my buddies house about 3 more miles. When I left my buddies house I didn't make it maybe 5 miles before it would try to overheat again. Poped the hood released the overflow pressure but it didn't work this time. When I got home I sat there with the engine idle. No heat. No AC and the coolant will not flow out of the resivoir tank. What is going on here. This has slowly got worse and worse. Before I could just pull over do pop the hood and release and on my way for a week or 2. Now not working anymore. My fan works like a champ. Please don't say the word "block".....How about water pump or radiator even. Maybe even my tubes. Thx, LNCD UP
