WHEN SET FOR HOT WATER RADIATORS ARE HEATING ALSO


there should be a seperate adjustment for hot water and for central heating, if they are on timer that is. If you are switching on at the boiler / combi check for the seperate switches

1989 ford f150 over heating


I assume you mean the engine is over heating. Would check the thermostat first by removing it and see if it still over heats.If not, replace the thermostate, if it does then the radiator might be plugged up and would need to be fixed or replaced.

No heat when stopped for traffic


1-your thermostate is stuck open half way. thermostate is a simple device that made of enlarging metals when heat is applied. it suposed to be in close position to allow engine heat up, when specified temp reached it opens and let it flow and radiator tries to keep coolant cool.when it is broken it stucks or it acts slow or it wont acts at all. in your situation it is stuck open half way. it allows enough water to be heated but flow is limited to heat cabin heater.

2-if there are cabin heater selenoid/selenoids for two different temperature for cabin left and right, on some instance those selenoid valves to adjust cabin heater stuck open or closed like thermostate acts on first case. so heat is not enough to heat up cabin heater.

MY A/C WORKS PROPERLY HOEVER THE HEATING SYSTEM IS NOT WORKING. AIR COMES OUT BUT IT'S COLD. WHAT SHOULD I BE LOOKING INTO?


a stuck or broken thermostate would do that if the moter temp takes a really long time to warm up the thermostate is stuck open and needs to be replaced if the moter warms up to fast or over heats the thermostate is stuck shut and needs to be repalced. the heater core its self could be plugged and may be fixed by back flushing with water if you do it your self flushit seperate from the moter to prevent what ever may have plugged it from re-entering it.

What will happen if thermostat will be removed and


Good question: The thermostate acts as a valve (of sorts) allowing the engine to stay at a relative constant temp. If run without an engine will typically run too cool (this is not good as engines are designed to run at specific heats for best efficiency and motor oil too is designed to run a a designed heat. An engine can go the other way too and over heat. As mentioned the thermostate acts like a valve controling the flow of coolant thru the block and radiator. The run thru block is a long one and it will certainly pick-up heat however running without may cause the coolant to run too quickly thru the radiator so little heat will be lost. (imagine a lit candle run your finger thru it quickly and no heat exchange as it you will not burn your finger, slower you'll get the heat from the candle and burn your finger. In short use a thermostate, your engine was trully engineered to have one.

I hope this expalins it for you,

I do not have enough heat in my 1994 dodge ram truck


I expect the thermostate is stuck partially open not allowing the engine to come to proper temperature. Replace the thermostate found under the goose-neck (follow the upper hose back to the engine) under this piece is the thermostate. Be certain to clean all of the old gasket material away and use a new gasket. Watch to be ceratin the thermostate is not put in upside down, if this happens your issue won't be not enough heat but over heating.
I hope this may have been of help,

Over heating


The water pump has what's called a 'weeping hole' built into it. If the pump is bad You'll se water coming out of the hole. When was the last time you flushed the radiator? It may be your radiator cap is bad, they should be changed once a year & the radiator flushed. You can also test ur thermostate. take out ur thermostate & put it in a pot of water so that the water covers the thermostate. Then put a cooking thermometer in the pot to & heat the water til it says 195. u should see the car thermostate begin to open. if it don't it's bad & needs replacing.

Heat blowing Cold when in drive. When in Park, it is warm


have you chg. any thing lately like thermostate? added any coolent to system? if not, thermostate could be stuck in the open position. if stuck open, setting still, it will throw heat, but moving coolent flows to fast and does not get a chance to get hot. if you did chg. thermostate it could have a air pocket in the system. and also adding coolent can create an air pockets too. you will know this when your traveling down the road and temp guage fluctuates up and down. witch means air in system.
