They may have left off the air intake sensor that is located on the air snorkel that they had to take off to get to the water pump and belt .If you can go to autozone or advance auto have them scan your computer ,they do this for free.Also is the vehicle running alright ?

Cylinder #1 misfire. If the engine is running fine the code will reset on it's own after 40 cycles of the ignition key. If the engine is running poorly it could be due to bad spark plug or coil pack.

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.

2003 kia rio- water pumps


I would follow the mechanics recommedations. I think he's taliking about the cam and crankshaft seals. Yes the water pump should be replaced as well. The pump that sprays windshield washer fluid onto the windshield is called the windshield washer pump. The water pump is on the engine and pumps water (coolant/antifreeze) through the engine to the radiator and heater core.

Water leaking


The weep hole of the water pump may be leaking. You see the water drip at the lower part of the front of the engine. After you park the truck, slide under the front of it and with a flash light look at the bottom of the water pump and see if you see a trail of water happening there.
