HELP!! coolant problem.
I have a 1996 grand marquis... So I just replaced my bad water pump and thought the leaking coolant problem was over. Then Last night i was driving down the highway and my car started smoking really bad (steam actually) the teperature started to rise, so before it became a problem, i pulled over and got a tow. Upon inspection all the hoses were intact, but the top of the engine had a little coolant on it under the engine cover (just condensation). So i topped off the coolant and started it up. It got up to normal operating temperature and it was working FINE, a little steam from the coolant that was still on the engine. but we saw no leaks. The majority of the steam was comming from on top of the block behind the alternator. We were perplexed, until... I turned the AC on and turned the heat up, then it REALLY started pouring on the block and we had a big cloud of steam rush up from the engine. I immediately shut it off. I checked the oil, theres no water in the oil (thank god). Are there hoses that run underneith the intake manifold? Or is the manifold itself cracked and leaking? Or is it something i'm missing? Please help!
