Ok so I had new tires put on it today and was out driving it around on the freeway to test it out. Drives a lot better. I got it back in the garage and I feel the hood and it nearly burned my hand. I opended it up and took out the dipstick. No smoke coming off but the it was hotter than you know what. The engine block is really really hot. It's not normally like that. I know the coolant needs to be flushed but the wp is only about 20k miles old. The temp guage only gets to about half way and it's really not picking up like it used too. Then u turn the ac on and the lights dim and the car barely wants to move. Something is not right here and it's starting to bother me. Also it just started leaking oil around the pan and the tranny. The tranny isn't leaking, motor oil is just dripping off of it. Any ideas to my mind at ease would be very helpful thanks guys!
