The heater control valve (sometimes called the water flow valve)controls the flow of coolant into the heater core from the engine.
Heater control valves are operated in three basic ways: by cable,thermostat, or vacuum. Cable-operated valves are controlled directlyfrom the heater control lever on the dashboard.
Cable-operated heater valve used to control the flow of water or coolant through the heater core.Thermostatically controlled valves feature a liquid-filled capillarytube located in the discharge air stream off the heater core thatsenses air temperature and modulates the flow of water to maintain aconstant temperature regardless of engine speed or temperature. Mostheater valves utilized on today's car are vacuum operated. These valvesare normally located in the heater hose line or mounted directly in theengine block.
To replace a heater control valve:

• Refer to your vehicle's service manual to locate the valve.
• Drain or lower the fluid level in the cooling system.
• Unclamp, unbolt and unplug the valve.
• Reverse procedures to complete installation.

first cylinder 4 is the last on the passenger side . first pull the coil out and check if there is water where the plug is. if there is take the water out and dry up the coil. if you find water you got a crack manifold or a bad intake manifold gasket. if there is no water replace the coil. good luck
