Most newer cars do NOT HAVE A HEATER SHUT-OFF VALVE. The water continually flows into the heater core inside the passenger cabin and is regulated by a series of 'doors' that direct the air-flow over either the evap. core (for A/C) or the heater core for heat.

A broken or leaking heater core is a mess and very expensive to replace. The whole dash has to come out: glove box, dash pad, cigarette lighter, ashtray, all of that lousy fake walnut trim, etc. It takes almost 8 hours just for the 'teardown' to get to the faulty heater core that is probably leaking fluid onto the floorboard on the passenger side. Plus, since all of that crap is PLASTIC with little lock-down tabs, you WILL break a great many and there is not a glue made on the face of the earth that will repair automotive plastic. (That's how they make MONEY.) So, get a bunch of Velcro, a whole roll - you'll need it all if you begin to attempt this repair.
At $95 per hour at a dealership, the 'teardown' cost is $760. Expect to pay around $1,800 for a heater core. If you have an independent shop have at it - INSIST ON A GENUINE FACTORY PART. (I once had them use an aftermarket heater core and it failed three months later, so I got hosed for a very large sum of money, since the original guy that did the work was two states away.)

There are two cheap fixes: 1) go buy a VISE-GRIP pliers and clamp down the hose leading from the engine to the heater core, try to find ones with FLAT surfaces on the pliers. 2) Cut the line (from the engine to the heater core and install a manual heater shut-off valve that will prevent the flow of coolant. Check out a bone yard, but MEASURE how big your heater hoses are FIRST, since different cars have different sixes of hoses.
Keeps engine coolant from going through heater core when it is not needed.
It does not have a water flow valve in the heater plumbing.It does not have a water flow valve in the heater plumbing.
sounds like may be to much heat. if its coming out of the pressure relief valve located on top.turn heat down, you said coming out the valve i thinking you mean the valve on top of heater.if so thats it. faulty valve or water is getting to hot.hope thathelps
A TNP valve is a temperature and pressure valve found on a water heater.
No, cold wter enters the water heater at the bottom of the tank, right where thee valve is.
A heater control valve is simply a water valve which allows more or less water to circulate through the heater core, depending on how much the valve is opened. When the engine warms up it heats coolant (mostly water) in the water jacket of the engine. To keep the engine from overheating, the water pump circulates water through the radiator once the engine temperature reaches the set-point of the thermostat. When it's cold outside the engine STILL reaches a temperature that allows you to make use of the engine heat when you open the water valve of the heater. Heater control valves take many forms but basically they all do the same thing; they open to allow heated engine coolant to circulate through the heater core or they close to stop the coolant from flowing. Heater control valves can be manual (cable controlled or even lever controlled), vacuum (which allows the engine vacuum to control the position of the heater control valve based on where you set the control knob) or electrical which allows for greater flexibility and even allows the auto manufacturer to connect the heater controls to a computer or other electronic control device.
Yes! Connect a garden hose to the output valve of the water heater and open the water heater valve to put hot water into the kiddie pool. This is the fastest way to warm a children's pool.
There isn't a water control valve.
The heater output temperature is regulated by airflow control doors inside the dash, not a water valve.
That is called a heater control valve. When you are not using your heater, vaccume closes a small valve that's in the control valve and stopes the water from going through the heater core. Therefore you get no heat inside of the cab.
Ok, I got the answer to this question. It seems that there is not a heater control valve in the heater hose line.
Could be water-heater problems or faulty valve.
