Im having problems with getting my heat to work, i changed the water pump,thermostat,radiator,tension pully. and my heat still not working like my car over heat sometime, but the heat blow out a lil bit but not alot, do u know the problem?

Are you adding coolant when you let the air pockets out ? Sounds like its still low on coolant.

A cracked cylinder head?? Head gasket not sealing due to a warped cylinder head?

Tension pulley might be the notice but I don't think that would make it run hot..You changed the thermostat and said the water is circulating..If it's not leaking water I would check the Catalytic converter under car...When they start getting clogged up it will make your car run hot because the exhaust can't get out like it supposed to...You can also put a thermostat in that opens sooner

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.

Ok, first thing, its a Ford Product. Thats an issue for another time. But for this problem, perhaps you bought the wrong thermostat for the car. They are made to open at specific temperatures. If the one you put in opens at say 200 degrees, and your car wants one that opens at say 145 degrees, then your gonna over heat even before you have any water flowing through the engine to keep it cool.

First of try to understand exactly what part you mention exactly how they work or function

1. please place a new low speed relay as it try to make out thermal heating cool at it's initial 1st stage level of heating so that the temperature remain maintain if thus it reaches the second level of heating then the high speed relay act at that time & the speed of radiator fan increase to get thermal heating in control.
2. the thermostat regulate the heating temperature of the engine it senses the temperature & signal to the relay the relay then react according to the temperature level of engine at low heating it operate the low speed relay & high temperature it signal to high speed relay so the engine temperature does not rise to extended level of heating or overheating.
3. see for thermostat valve is failure if that so replace it new sometime most of the mechanic change it or cancel it so that the temperature does not rise as this thermostat help engine maintain it's ideal temperature which is required by the engine for regular or good working even at extreme climatic condition.
4. Do check for every tensioner or Ideal Bearing as far consider on the No. of miles or Km the vehicle has run according to us the tensioner or ideal bearing are suppose to be replace at an interval of 30000 to 35000 Km. but this replacement include both Engine timing belt & tensioner & ideal tensioner bearing.
5. A water pump flow depend on the tension of the drive belt some vehicle come with water pump which drive on inner timing belt tension & some on the fan belt or external tension belt of engine.

for further more FAQ do send in or place your problem we will sort it out till then have a safe drive & happy motoring from siddhanth.....!

If your guessing the thermostat, I think your guessing right. Easy job to replace it, use a fail safe thermostat next time to avoid this problem in the future. Good luck.

i agree water pump , but thermostat can go bad very fast some times they will have a defect when u buy them for that you can do a simple test ,,,put the thermostat in boiling water if it expands that means its working

Check the Tension on the Belt. If it is not tight enough or you need a New Tensioner for the Belt, It will run hot. It is not letting the Water Pump Cool the Motor fast enough. You might also Check the Radiator. If the Radiator is Even a Little Clogged, It will overheat. Also, Check the Fan clutch, If it is not working Properly, You will overheat. Let me know what you find!

all engine overheating is du to malfunctioning cooling parts or coponents in the engine or attached to engine or car ... first ck for leak , coolant or water leak , then ck if the thermostat open on time to let the waterpass trhu ck the cooling fans if they working propely and kick on time , ck for an cloged radiator that neded to be fluch up nicolas
