If the coolant is in the cab they did not cause the problem changing the manifold gasket. It sounds like the heater core has failed, which is under the dash.

If you had a welder you could slide the bolt into the hole tack weld it on and that tap lightly with a hammer and turn it out with the bolt. You want the bolt to be 3 or 4 inches long and just slide in one weld on each side and you should get it to come out.

First, remove the ps belt by loosing the adjustment bolts, then remove the hoses from behind it, then unbolt the bracket from the engine that the pump sits in. I believe that there are three bolts that do this. One off of the exhaust manifold, one on top and one underneath. Once you have gotten pump off of the motor you need to remove the pulley from the pump. KD tools make a great tool for this, part # KD 2897, about 60 bucks at napa. Follow the directions with the tool to remove the pulley and to replace it on the new one. New pumps don't come with the pulley and can be bought with the resevior. The pulley has to come off to get the pump out of the mounting bracket.

Have you chacked the condition of the coolan, to make sure it is not mixing with engine oil? The reason why the temperature gauge is not registering is maybe bacause the coolant level is way too low.
