Try to borrow a good size make-up mirror from a female friend. With the mirror in hand and as good small flashlight, look under the area of the waterpump while the engine is cold. You should see a greenish or redish stain on the bottom of the waterpump shaft. The pump usually only leaks when it's running and when it gets to cold temps. Place a piece of cardboard under the crossmember when you park the vehicle for the night and look the next day for leakage indications. Thanks, Dana

When you start the engine look at the water pump and see if engine coolant is pouring out the weeping hole.If so you need a new water pump.Use a light source to see this

My 2007 lincoln mkz overheated today.


possibly a hose or water pump leaking, but only while driving when full pressure is on the system. first check your oil and make sure theres no water in the oil.if no water in the oil, then fill the radiator,and let run in driveway until it reaches temp 190 to 210 and look for water leak then. If it were just the thermostat then you should have a boil over in coolant tank and wld/shld be able to smell or see the coolant loss. also inspect your radiator sides front and back, your radiator may have a hole

The coolant light flashes on but the temp gauge does'nt go past the middle when the car is running


YOUR TEMP GAGE WILL NOT REGISTER CORRECTLY WHEN THE COOLANT FALLS BELOW A CERTAIN LEVEL. WHEN IT IS SMOKING IT IS EXTREMELY HOT. IF YOU HAVE A COOLANT LEAK THAT BAD IT SHOULD BE NOTICEABLE EVEN WHEN IT IS NOT HOT. YOU NEED TO FIND THE SOURCE OF THE COOLANT LEAK. WATER PUMP, COOLANT HOSE, FREEZE PLUG, HEAD GASKET, RADIATOR CAP LEAK, OR RADIATOR, OR HEATER CORE. CHECK THE ABOVE AND YOU WILL FIND THE SOURCE OF THE LEAK.

My car overheats very easy.i can drive 1 exit on the highway and the temp goes up very fast. i dont know what it could be. there is always fluid in the reserve area and doesnt seem to be getting low or im...


COULD BE THERMOSTAT IF TOP RADIATOR HOSE IS NOT HOT AND BOTTOM RADIATOR HOSE GOING TO WATER PUMP IS HOT THE THERMOSTAT STICKING PARTIALLY CLOSE.IF TOP HOSE IS HOT THE RADIATOR,ENGINE BLOCK HEATER CORE NEED FLUSHING OUT.IF WATER PUMP WEEP HOLE LEAKING REPLACE WATER PUMP, FAULTY WATER PUMP WILL CAUSE ENGINE TO OVER HEAT.REPLACE RADIATOR CAP MAKE SURE YOU HAVE 50 / 50 MIX SOLUTION ANTIFREEZE AND WATER IN COOLANT SYSTEM. IF ALL LOOKS GOOD CHECK ENGINE OIL ON DIP STICK, IF OIL IN DIP STICK LOOK LIKE MILKSHAKE YOU HAVE BLOWED HEAD GASKET THAT WILL CAUSE ENGINE OVERHEATING WHILE DRIVING CAR IN SHORT DISTANCE AND ENGINE OVERHEATING.

Hi I have a late 1998 Holden Isuzu Rodeo D Cab 2.8L turbo diesel 4WD with 274000Km very well maintained it has a suspected overheating problem when under load. The radiator and hoses are new under a year...


the temperature gauge range of movement is still considdered an acceptable range and depending what weather conditions and other loading on vehicle eg going up hill also while towing. But some things ive come accross like possibly the water pump, at higher speeds the impeller could be loose on shaft and with pressure it may not be turning at proper speed, I would replace the thermostat for saftey measures also, while you looked at the water pump. Check out the heater hoses and pipes that run behind the engine to the other side for leaks also. check connections of temp sender unit wire on thermostat housing(there are 2 sensors on it) its the smaller of the 2.the other one is for cold starts

Low fluid light means check your coolant which prob whats on the ground. Depending on the rate of leakage fill coolant start try and locate leak sounds like a hose or water pump slow leak prob water pump fast leak hose good luck

I have a 300zx non turbo , it is not leaking coolant , electric fan is working good but whene i drive on a hyway , the temperature start going up like 3/4 on the gage, as soon i star driving in the city...


I doubt very seriously the temp problem has anything to do with the timing issue. It sounds more like the water pump is going bad or you have low coolant. When your moving the fan should be free wheeling if it isn't the clutch is bad or the Fan motor is bad. I would look at the Fluid level and water pump for being the issue here.
