Check all of these...... Radiator fan, check if its running in a certain temperature. Relay and fuse. Thermostat valve in the upper radiator engine inlet. Temperature switch sensor, usually in the radiator might be the wire is disconnected or short it, FAN will start automatically. Check ur coolant, if rusted, touch the bottom part after running the engine for 15min., if cold at the bottom, u got clogged radiator! Finally look at ur oil cap, if there is a whitish substance, u got a BLOWN HEAD GASKET! Taaah!

However when I turn the heat on it does not allow the car to heat up immediately, then when my windows are fogged up it takes time to clear the windows what could this be. thank you


It takes time for an engine to warm up. The heat from the heater comes from the water running through the engine. If the engine is cold, it will take a while for the heater to work. If the engine has a thermostat problem, it takes even longer. The thermostat is not supposed to open until the engine is heated up. If it stays open, the cold water takes a lot longer to heat up. A quick check is when the engine is cold, start it up and with the radiator cap off , have a look in at the radiator water. it shouldn't be flowing as the thermostat shouldn't be open. If the water is flowing on a cold engine, I would say the thermostat has jammed open and that's why its taking so long to heat up.

1997 ford Taurus 3.0 6cyl. Has not heat


Empty cooling system and reverse flush the heater core with water hose till water comes out clear. Then reverse procedure till water is clear. Fill system with water and turn car on, while car is running open drain plug and continue to keep radiator full while draining it at the same time turn on your heater with heat on high and blower on high When water is clear flush system and wait for engine to cool down. Refill with antifreeze and turn engine on, check for leaks and to see if you have heat. If still no heat change heat core.Let me know how you make out.

Why is my car leaking water out of the radiator cap only when the heat is off but when the heat is on it don't leak ???


turning the heat on lowers the temperature of the water running through the engine which in turn lowers the pressure in the radiator

Jeep patriot no heat


fan blows?
engine reaches and holds 180F or more , normal engine temp?
(use a IR pyro gun to measure it)
ever go a cooling system flush, if not the heater core could be packed full of junk.
id the dampers fail , its not in heat mode.
check the dampers after checking engine heat.

it only takes 2 things to make any water to air heat exchanger to work.
hot water
and actual air flow.

check for hot water first (engine coolant)

Overheating and no heat


With what you describe sounds like the hot water is just heating up but not circulating and cooling correctly. Possible causes, airlock, faulty water pump, check fan belt tension, not broken etc, blockage in engine water way or collapsed hose. Are you losing water at all? Head gasket?

My 99 alero v6 is over heating not leaking ight mite be hoses or thermostat . or head gasket but when it overb heats the smoke comes from the top of the engine


REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP.IF CAR OVER HEATING WHILE IN MOTION.MORE LIKELY ITS THE THERMOSTAT,LOW COOLANT IN RADIATOR OR COOLANT SYSTEM,BAD WATER PUMP,WATER PUMP WEEP HOLE IS LEAKING, WATER PUMP NEEDS REPLACING.CHECK ENGINE OIL,IF OIL LOOKS LIKE MILK SHAKE YOU HAVE LEAKING HEAD GASKET.IF CAR IN PARK AND OVER HEATS WHILE IN A LONG TRAFFIC LINE OR.BANK DRIVE THROUGH COOLANT FAN NOT TURNING ON, BECAUSE THE ENGINE COOLANT TEMPERATURE SENSOR FAULTY.CODE SCAN CAR FOR FAULTY COOLANT FAN RELAY OR FAULTY PCM. CHECK COOLANT FAN FUSE, AND HOT WIRE THE COOLANT FAN TO MAKE SURE ITS WORKING.IF COOLANT FAN DONT WORK WHEN HOT WIRED. COOLANT FAN NEEDS REPLACING. REPLACE BOTH RADIATOR HOSES, REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP.BUY NEW COOLANT ADD 50/50 WATER AND COOLANT.IF ENGINE OIL HAS ANTIFREEZE IN IT.REPLACE ENGINE OIL AND OIL FILTER TO KEEP FROM LOCKING UP THE ENGINE.GET CAR FIX.DONT KEEP DRIVING IF IT KEEP OVER HEATING,ENGINE DAMAGE WILL OCCUR.I HOPE INFORMATION I GAVE YOU WILL FIX PROBLEM.PROBLEM COULD BE LEAKING RADIATOR HOSES BUT CHANGE THERMOSTAT THATS FIRST THING I WOULD CHANGE BECAUSE IF IT CLOSED, ENGINE WILL OVER HEAT AND CRACK CYLINDER HEAD OR CRACK PISTON, COOLANT NEED TO CIRCULATE THROUGH THE ENGINE TO TAKE AWAY THE HEAT FROM ENGINE.

Took out the thermostat, replaced the radiator, the water is circulating in the radiator but it is still running hot. what do i do next?


Overheating can seriously damage a car's engine if left unchecked. Although overheating simply means that a car's engine temperature exceeds normal operating temperatures, the causes of overheating are varied. What follows is a brief list of some of the most common causes of engine overheating.

    Faulty Radiator
  1. A car that overheats will often have a faulty radiator. A radiator is responsible for cooling hot engine coolant that picks up heat from inside a car's running engine. A radiator "radiates" the heat from engine coolant out into the outside air. A faulty radiator loses its "radiating" effects and allows engine coolant to become overheated, thus rendering it ineffective at adequately cooling and engine.
  2. Faulty Water Pump
  3. A faulty or malfunctioning water pump prevents adequate engine coolant flow and can cause a car to overheat. A water pump serves to pressurize and propel engine coolant throughout a car's engine and radiator to increase the heat-reducing capabilities of engine coolant. A faulty water pump loses its ability to adequately pump and propel engine coolant, and can cause a car to overheat.
  4. Coolant System Leaks
  5. A leaky engine coolant system reduces the level of circulating engine coolant, which increases engine temperature and leads to engine overheating. Radiators, water pumps, and coolant system hoses and seals--all of these coolant system parts can develop leaks, which can result in low coolant levels and engine overheating.
  6. Faulty Thermostat
  7. A car thermostat regulates the flow of engine coolant. A thermostat is a heat-sensitive valve that opens when a car engine reaches a set operating temperature and closes when a car engine is cold and warming up. If a thermostat gets stuck in the closed position, coolant will be prevented from reaching the engine, which will quickly lead to engine overheating and potential engine damage.
  8. Low Engine Oil Level
  9. Engine oil, in addition to lubricating an engine's internal parts, helps to keep engine operating temperatures reduced by eliminating friction within the engine. If engine oil levels are low, friction and heat build up inside an engine, a condition that causes increased engine operating temperatures and can lead to engine overheating.

96 toyota Hiace disel engine. it over heating


engine oil mixing up with ur coolant indicates engine serious problem/ ur cylinder head gasket is broken and ur engine needs overhaul...bet ur engine must have overheated several times already that causes damage on ur cylinder head gasket..u need a good mechanic to restore the engines original condition

Engine light wenton, car heated up, car would not


If the engine overheated while driving, damage to the cylinder head gasket or engine block/cylinder head may have been done, which would prevent the vehicle from starting.

A standard engine compression check will tell the tale.

I have water leaking from the engine, but don't know where from. The radiator has been changed the water tested for emmissions, pressure tested and still water is leaking. The heating blows hot when...


if you see the water leaking form the front side of the engine usually from the water pump since the pump is not running you also wont get heat, bit when you pressurise the sys you are forcing the hot water into the core and you have heat, it is the water pump.
