I recently had the water pump replaced on my 1994 Mercury Topaz. One day later it worked fine going to school but overheated on my way home. A hose was loose but that has since been fixed. The reserve tank is way past full hot and will not go down, I can not see any coolant in the actual radiator. What is wrong. The car otherwise runs better than it has in the past. PLEASE HELP!!!

There doesn't seem to be any coolant leaking out onto the ground and the oil was changed a month ago and still looks new.

Take it back to where the work was done and explain the problem, the least they would do is check it out for you.

My guesses:
1. Might be a faulty thermostat
2. Coolant might be leaking into the oil, which would mean you have a blown gasket. Check your oil for a milk type coloring.
3. Might need a new radiator.
Check to see if there are any coolant leakes under your car after it is parked and look all around your engine for any signs of wetness that might have been sprayed on by the radiator grill.
#1 would be the cheapest to replace, followed by #3. #2 will cost you ALOT to get fixed if they have to replace the entire cylinder head gasket.

If all the leaks have been repaired, the safest and best time to add coolant to the radiator is when the engine is completely cooled. If after you fill it up, it leaks out a day or two afterward, you may have a blown head gasket or a cracked head.
Or if who repaired it forgot to connect the tube for the coolant reserve tank, then coolant would not go from the tank to the radiator.

the radiator cap is defective. would You please, replace it.
the radiator cap has two seals one let the coolant go to reservoir,and the other, don't allow the coolant go to the street or ambient,the first one allow the coolant return to the radiator.
BUT, when the second suck air from the ambient at the moment the coolant is suppose to return,then the coolant remain in the resevoir and cause over flow when You driving the vehicle .
droping the coolant though a hose direct to the road , so You will never find out,when, the coolant leaks

Keep that rad full for now! You have a leak in the rad or hoses.
In the cold weather the thermostat valve which controls collant flow to the rad may never open, keeping the coolant in the engine.
A dry engine will overheat in the wink of an eye!!!!

souds like you have a stuck thermostate when they change pumps and things like that in the cooling system some times dirt or calcuim bulid up can come loose and plug up the radiator or the thermostate. good luck but i would not drive it very far if it dose not have water in the radiator and over heats cause you can cause more sever problems with the motor like buring it up .

Talk to the person who replaced the pump. He may have accidentally clogged one of the coolant lines.
