Question about 2001 Volkswagen Golf

1 Answer

Overheating I have an overheating problem. Even though I have checked the water and oil level, it still overheats. This only happens in traffic. I do have a squeaky fan belt, could that be the problem or do I have a air lock?

Sounds like it could be an airlock - or a blockage in the radiator restricting the coolant flow.

With either problem, you might want to try a flush through and clean out. Use a good radiator flush and clean, its usually got a good degreaser built in, that way you will get rid of any oil based contaminants.

How do i find out whats causing my car to overheat


How to Troubleshoot an Overheating Engine By Deanna Sclar from Auto Repair For Dummies, 2nd Edition
1 of 9 in Series: The Essentials of Checking and Maintaining Your Vehicle's Cooling System The first sign of a vehicle overheating is either when the needle on the temperature gauge pushes its way into the ominous red zone or the "Check Engine" or "Temperature" malfunction indicator light on the dashboard casts a sinister glow. Left alone, the liquid in the radiator eventually boils over, and steam rolls out from under the hood.
If your vehicle overheats often and constantly loses coolant, the problem may be leaks in your cooling system. If your vehicle overheats in normal weather and traffic, you may need to add liquid to the system, replace the thermostat, adjust or replace the accessory belt, or check the water pump.
The first thing to check if your vehicle overheats often is the pressure cap. Sometimes the gasket on the cap deteriorates and lets pressure escape, which causes the cooling system to malfunction. Most service stations can test your cap for you and tell you whether it's in good condition.
Some overheating problems aren't related to the cooling system at all. Here are some other circumstances that can cause a vehicle to overheat:
  • Late timing: If your ignition system is malfunctioning, late timing may be causing your vehicle to overheat because the spark plugs are firing the fuel/air mixture after the piston moves back down from the top of its stroke. Late timing alone doesn't cause an engine to overheat by more than a few degrees, but when coupled with other problems, it can bring the engine temperature to a critical point. Have a service facility place your vehicle on an electronic diagnostic machine to check your timing and adjust it if necessary.
  • Plugged radiator: Because plugged radiators cut down on the system's liquid circulation, the system can't cool efficiently. The remedy is to have a radiator specialist remove and inspect the radiator. If you're lucky, just steam-cleaning the radiator does the job; if you're not, the solution may be more expensive.
  • Slipping accessory belt: If you can see and reach the accessory belt that drives the water pump, check to be sure that there's no more than about 1?2 inch of give. If the belt seems loose or frayed, you can try to replace it. If you can't do the job, have a professional deal with it.
  • Collapsing bottom radiator hose: Occasionally, a bottom radiator hose begins to collapse under the vacuum that the water pump creates, and the impaired circulation causes overheating.
  • Low oil level: A vehicle that's low on oil tends to overheat because the oil removes from 75 to 80 percent of the "waste heat" in your engine (in addition to doing its other job of cushioning the moving engine parts).
If you're one quart low in oil and your vehicle holds five quarts, the oil will carry away 20 percent less heat than it should.
Under normal circumstances, you can prevent overheating by checking the level of liquid in the system and maintaining it properly.

Why won't my 1999 jeep Cherokee limited V8 4.7 liter stop overheating?


A possibility is the water pump. This is what circulates the water through the engine and back to the radiator for cooling. Water pumps consist of several vanes attached to a rotating shaft. If a few vanes are broken, you'll get reduced water circulation, causing overheating.

Engine over heated stalled out and will not start


FIRST OF ALL CHECK ENGINE COOLANT LEVEL IF LOW YOU NEED ADD MORE COOLANT CHECK FOR LEAKING TOP AND BOTTOM RADIATOR HOSES, CHECK RADIATOR FOR LEAKS. IF YOU DID NOT LOSE MUCH COOLANT THERMOSTAT COULD BE STUCK CLOSED.WHEN ADD COOLANT CRANK VECHICLE AGAIN CHECK BOTH RADIATOR HOSES THEY BOTH SHOULD BE HOT. IF TOP RADIATOR HOSE GOING TO ENGINE BLOCK COLD AND BOTTOM RADIATOR HOSE COLD WARM THE THERMOSTAT IS STUCK CLOSED. IF ENGINE OVERHEATING WHILE SITTING IN LONG TRAFFIC LINE YOU COULD HAVE FAULTY ENGINE COOLANT TEMPERATURE SENSOR.IT CONTROLS COOLANT FAN AT SET TEMPERATURE.IF COOLANTS FAN NOT RUNNING WHEN OVERHEATING.EITHER COOLANT FAN FUSE RELAY FAULTY OR FAN MOTOR DEFECTIVE OR FAN MOTOR WIRING CONNECTOR HAVE BROKE WIRES.IF COOLANT FAN IS RUNNING WHILE ENGINE OVERHEATING CHECK CRANK OIL AT OIL DIP STICK OIL LOOKS LIKE MILK SHAKE YOU HAVE BLOWED HEAD GASKET. WARNING DONT KEEP DRIVING VECHICLE WHEN ENGINE OVERHEATING YOU WILL CAUSE ENGINE AND TRANSMISSION DAMAGE.

1998 cadillac catera oil pressure light come and and the car overheats when sitting in traffic....


CHECK ENGINE OIL LEVEL SHOULD BE ON THE FULL MARK ON ENGINE DIP STICK. IF OIL LEVEL IS LOW.LOOK FOR OIL LEAKS UNDERNEATH CAR.IF ENGINE NOT LEAKING OIL CHECK OIL PRESSURE SHOULD BE 22 PSI @ 900 RPM IF NOT OIL PUMP FAULTY OR YOU HAVE WORN ENGINE BEARINGS.IF OIL PRESSURE OKAY YOU COULD HAVE FAULTY OIL PRESSURE SENDING UNIT. CHECK COOLING FAN TO SEE IF CAR COOLING FANS RUNNING WHILE ENGINE OVERHEATING.IF NO CHECK COOLING FANS RELAY AND FUSE IF ALL IS GOOD ENGINE COOLANT TEMPERATURE SENSOR FAULTY. IF COOLING FANS RUNNING WHILE ENGINE OVERHEATING.HAVE RADIATOR AND ENGINE FLUSHED OUT. REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP.

My 1995 toyota avalon is overheating. When this happens, antifreeze fills up my reservoir container, even when I didn't put that much antifreeze in it.


Check to see if there is water in the oil...If there is water in the oil then it could have a head gasket problem..Did you ever replace the thermostat? If it is stuck then it would also cause overheating...Excessive exhaust backpressure because of a clogged catalytic converter could also cause overheating..Also check belt tension and condition. A loose belt that slips may prevent the water pump from circulating coolant fast enough and/or the fan from turning fast for proper cooling...Another thing it could be is a faulty Water pump -- Any wobble in the pump shaft or seepage would call for replacement. In some instances, a pump can cause an engine to overheat if the impeller vanes are badly eroded due to corrosion or if the impeller has come loose from the shaft. The wrong pump may also cause an engine to overheat. Some engines with serpentine drive belts require a special water pump that turns in the opposite direction of those used on the same engine with ordinary V-belts... Also check the Fan -- With mechanical fans, most overheating problems are caused by a faulty fan clutch, though a missing fan shroud can reduce the fan's cooling effectiveness by as much as 50% (depending on the fan's distance from the radiator) which may be enough to cause the engine to overheat in hot weather or when working hard.

Car overheating


First, plastic tube may be the overflow vent from the coolant bottle.Check to see where the attached end goes. You are going to have to check engine for coolant leaks (carefully refill system without spilling anything, then look for dripping anywhere. Look for leaks from all hoses, fittings radiator, water pump etc) After checking for leaks, start it up and check again (watch where you put your hands though) While running, check that the fan comes on when the vehicle reaches operating temp.(no fan, check fan motor, sensor & relay) Turn the heat on (does it have heat?) Check temp of lower hose and upper hose. If overheat happens, is lower hose still cold? (likely bad thermostat). If you found a leak, replace whatever is leaking...best insurance is to change thermostat after any overheat. Last, is there any white smoke from tailpipe, does engine run rough? If so, could be a failed head gasket or crack in cylinder head. (at this point last thing to worry about unless there is excessive smoke or rough run or oil in radiator or coolant in oil).
