Question about 1999 Lincoln Navigator
Does the vehicle have any water or condensation from the tail pipe? or does it seem to use more fuel now or run rough? If you answered yes to either of these take the vehicle in and have a compression check done to see if you have high in one or more cylinders. The last time I had this problem the block was cracked and the pressure from the cylinder was forcing hot water into the heater system even though it was set to off. This can be a major issue.

Testimonial: "Yes, it is running rough too but the roughness started weeks after the heat issue. I will take it in to have a compression check and pray... Thanks!!!"
