CHECK TO SEE IF BOTH COOLING FANS RUNNING ARE RUNNING WHEN ENGINE RUNNING START OVERHEATING IF COOLING FANS NOT WORKING CHECK COOLING FANS LARGE FUSES IN THE ENGINE COMPARTMENT OR YOU COULD FAULTY COOLING FANS THERMO SWITCH BOTTOM LEFT SIDE OR RADIATOR.IF COOLING FANS IS WORKING WHILE ENGINE RUNNING.RADIATOR CORES AND HEATER CORE COULD BE CLOGGED.COOLANT SYSTEM NEED FLUSHING. THE THERMOSTAT PARTIALLY CLOSED CAUSE ENGINE OVER HEAT.CHECK WATERPUMP WEEP HOLE IF LEAKING WATER PUMP NEED REPLACING.

Check coolant reservoir level, check cooling fan if working, check if no leaks on the water pump...If engine newly installed, chances are drive belts are not installed properly.

MOST OF THE TIME WHEN CAR IS LEAKING ANTIFREEZE.CHECK ALL RADIATOR HOSES AND AROUND THE RADIATOR ON THE SIDES AND FRONT AREA WHERE COOLANT FAN IS.BUT BE CAREFUL DONT PUT HAND NO WHERE AROUND COOLING FAN.BECAUSE IT COULD COME ON WHILE YOUR HAND IS NEAR YOU CAN GET INJURED.ALSO CHECK AROUND WATER PUMP GASKET AND WEEP HOLE FOR LEAKING.IF YOU FIND NO LEAKS THEN YOUR HEAD GASKET LEAKING.CHECK ENGINE OIL IF OIL LOOK LIKE MILK SHAKE YOU HAVE HEAD GASKET LEAK.

Hi:
Coolant leaks can be tough to figure out where they are leaking, because it is tough to check around on a warm, running engine! I hope it isn't your recently changed water pump, but you can't rule that out. To help narrow things down, you can put papers down on your garage floor, and get a better idea as to what area under the hood it is leaking from, such as directly under the radiator, left side, right side, etc. Using a safe cooling system stop leak product is an option too. Bahrs leak is put in the radiator of every brand new car, and is a safe bet to aid in stoping a small leak. Either way, you need to narrow your search area if you want to find the problem, so work that first!

1 Inspect Cooling System Mix Coolant level low or flow is restricted. 2 Inspect Belt Incorrectly routed, adjusted, tensioned, missing, or worn water pump belt(s). 3 Inspect Oil Pan Gasket - Performance Ruptured, cracked or leaking radiator hose. 4 Inspect Radiator Cap Worn or damaged radiator cap 5 Inspect Thermostat Thermostat stuck closed 6 Inspect Fan Blade Broken, missing, or defective fan blade(s). 8 Inspect Water Pump Damaged, worn or leaking water pump. 9 Inspect Intake Manifold Plenum - Perform Leaking water pump gasket. 10 Inspect Cooling Fan Control Faulty cooling fan control or circuit. 11 Inspect Cooling Fan Switch - Radiator Faulty radiator cooling fan switch or circuit. 12 Inspect Engine Temperature Sensor Faulty engine temperature sensor or circuit. 13 Inspect Temperature Switch Damaged or faulty temperature switch or temperature switch circuit. 14 Inspect Fan Clutch Worn, loose or faulty fan clutch. 15 Inspect Ported Vacuum Switch Damaged, leaking, or faulty ported vacuum switch. 16 Inspect Radiator Obstructed radiator core or radiator cooling fins. 17 Inspect Head Gasket - Performance Head gasket leaking coolant into cylinders

have sex with it,.. it will feel better promis

1)check coolant level if low ,check for leaks,examine all hoses for cracks and wear also chek thermostat housing for leaks,if no leaks. 2)when engine is hot use your hand to check temp. of upper hose if hose is cool replace the therostat. also make sure the cooling fan runs when engine gets warm. otherwise bad water pump drive belt or belt not adjusted correctly,ignition timing incorrect,radiator core blocked(flush&fill) of radiator grill dirty, radiator cap not maintaining proper preassure(have it pressure check at a shop) good luck
