I have a question. I am a female and do not know about what the possible cause could be but here's my problem.
First off, I have a 2007 dodge charger. Not sure if it makes a difference but it's had one owner before me. Bought at 100k miles in Sept 2014. Now, these are my problems. When I test drove the car, my brother-in-law was with me and suggested I park the car and floor it to listen to the engine. Now, although I didn't feel it was a good idea, I did it because if I didn't, he would have. I'm mentioning this just in case that may be the reason for the problems I am having. Now with the problems:
1)The coolant. It had started overheating last year around March 2015. At that time, I would have coolant in it and it would overheat and the coolant would be gone. So, my father suggested it had a leak(which would explain the coolant being empty after recently filling it). Okay, well about Sept of 2015 I bought a leak fix for the coolant system. It worked amazing! So basically since Sept of 2015, my car has stopped overheating and I haven't had to add any water or antifreeze. I haven't had but a little bit of antifreeze in my car before now because I had water mixed with it. But recently, I filled my coolant with just antifreeze and ever since then my car has overheated once, AND it barely heats up the interior. After starting my car, I can turn on the heat defrost to clear my windows and before putting the antifreeze in it, it used to warm up no problem. But now, if I start it and I turn on the defrost, after sitting for a while it doesn't warm up anymore. It just stays cold. If I drive it for a little bit say across town maybe about 20 minutes and drive at least over 50mph, it will push out a little bit of heat and then turn to cold after a bit. Or if I slow down, it turns cold.
Now, is this because I added coolant ONLY instead of diluting it with water or is it because I still have a leak or what? Or maybe its my thermostat? My dad had bought one but never installed it. He also suggested that a cylinder could be blown which is possible since I had a diagnostic done shortly after it started overheating and it listed a cylinder/transmission problem.
2)My car shakes when slowing down around 60mph. Even if I fill my tires with the appropriate amount of air. Does this mean my brakes are bad? Or maybe my tire rods? I have googled a lot of different things so it may sound like I know possible causes but its all because I have researched and tried to figure it out because I do not have a boyfriend or a husband anymore to check these things out for me. My father does sometimes but he doesn't always have time.
Can anyone help me figure out these problems so I can get them fixed ASAP?
