Question about 1998 Volkswagen Beetle

3 Answers

Why is my 1998 vw beetle overheating?

I was leaking engine coolant I replaced two split hoses bled my radiator refiled with coolant. Now my car isn't leaking anymore but my radiator fans won't kick on and my car is overheating. Also when I tried to put the heat on it only blows cold air? When I remove the oil cap there is a little greenish gunk like water may be getting into my oil. I think I may have blown a head gasket. I wanted to try real steele to fix the head gasket. Any opinions on this product? What else could possibly be causing my car to overheat??

ALSO YOU CAN FILL THE EXPANTION TANK TO THE VERY TOP WITH THE ENGINE COLD, TRY TO START THE ENGINE, IF IT BLOWS THE COOLANT OUT WITH FORCE, THE CYLINDER HEAD IS DAMAGED, IF NOT COULD HAVE AIR IN THE SYSTEM. MOST TIMES IN THE HEATER CORE.

Sounds to me like a head gasket, you could try doing a pressure test to be sure. There is also a chemical test kit you can buy at your local car parts store. The tester sucks in fumes from the radiator and if the head gasket is bad, then the testing fluid will change to a different color.

Check around, I'm sure that you can find someone that can do it for less money.

I don't know if the radiator was bad or not, so I can't offer advice on that.

If your mechanic charges $100.00 per hour or more, I can see where they get the quote from.

If you need more assistance, post a comment.

Where are you located?

Maybe we can help suggest a mechanic for you.



Thanks,

Tim

SOURCE: Hi, my 99 vw beetle

Head gasket for sure would cause it to smoke and get hot. May seem like a stupid question, but did they check the thermostat? If head gaskets are good now and radiator was replaced, look for the obvious. Thermostat or air bound engine. An air pocket in the engine could also cause this. Need to bleed the air out of the cooling system. Some cars have a bleed screw to do this.

Hi, its not good news im afraid by you describing that with the coolant cap off and revving the car causes the pressure to build up and push the water back out it sounds to me like the head gasket is on its way out, what you need to do is take it to a garage and dont have a compression test done you need to have a gasses test done, you can buy these yourself if you want to and what it does is this.

its a plastic tube with blue liquid inside it then you take the coolant cap off and place this in its place you then run the engine and rev it up then you squeeze the rubber at the end of the tube and it then sucks the air out of the coolant and through this liquid then if it detects gasses from the engine in the coolant then this turns the liquid green and this is then telling you that the head gasket needs changing.

please dont let it keep over heating as this will cause the cylinder head to warp and you would then need to get it skimmed to make sure its not warped, get the gasses test done as a compression test dont give you a true reading as the engine is not running when they do a compression test.

let me know how you get on or if you need further assistance ok

plz rate this solution as i have a whole page of unrated posts, thanks

SOURCE: My 1999 Chevy Malibu is losing the coolant though the overflow hose by the resevior I've had my head gaskets replaced there is no overheating no water oil mix, but my radiator fans arent working I

Sounds like you need to disconnect the Radiators' electric fans and have them tested. You absolutely must have them working, or your car will overheat. Check to see if the Temperature guage is working.

You need to go to a good autoparts store and have them test the fans and charge and test your battery. You may need some sensors to activate the Radiator fans, but you could be running the battery down with shorted cooling fans.

There are also Relays which work with the Radiator fans. The overflow will stabilize once the water gets into where it belongs. Make sure your Thermostat is not clogged with the sealer.

Why is car overheating and upper radiator hose hissing and heater doesn't work after replacing water pump


the hose is leaking/split and the coolant level is low from a air blockage in the system. Find the highest point and undo the hose to let the air out . Open the heater to help bleed out the air. If not successful the have the system pressure bled.

1998 beetle leaking coolant


First of all, it's a VW, so it shouldn't have ANY "neon green stuff", it should have pink G12 coolant from VW. If the leak is getting worse, it's a hose failing, and splitting worse and worse under the cooling system pressure. find the leaking hose and replace it, but I'd recommend using a VW specific mechanic, so the "neon green stuff" doesn't make it back into your car, where it shouldn't be.

My 1997 Dodge Intrepid overheats. I've replaced the thermostat, and it continues to overheat. I noticed adjacent to one of the radiator hoses, a ribbed hose that is split. Could this cause the car to...


Now that you've eliminated the thermostat, it could be a number of other things. Don't drive the car too far until you've fixed the overheating problem - overheating can destroy an engine.

That split ribbed hose you see is plastic wire loom - it carries and protects electrical wires, and is not the cause of overheating.

1. Low coolant level
2. Radiator hose split/cracked, causing low coolant level.
3. Head Gasket - leaking, causing low coolant level
4. Thermostat - stuck closed (you eliminated this possibility)
5. Radiator cap - worn/damaged
6. Radiator fins - obstructed by debris/cardboard
7. Water Pump belt - missing/broken
8. Heater Core - leaking, causing low coolant level
9. Intake Manifold Gasket - leaking, worn, damaged
10. Radiator Fan Relay - faulty
11. Radiator Fan Blade - broken, missing
12. Radiator Fan Sensor/Switch - faulty
13. Water Pump - leaking, causing low coolant level
14. Radiator Fan Motor - faulty

My primary suspects would be Rad Fan Relay (#10), and
Rad Fan Switch (#12).

LOOKS LIKE IT MIGHT BE A RADIATOR HOSE IT HAS A BIG SLICE IN IT AND MY CAR JUST DIED ON ME WHILE I WAS DRIVING COULD THIS BE THE CAUSE OF IT DIENG ON ME


A split radiator hose will cause the coolant water from your radiator to leak out thus causing your car to overheat and 'die' on you for certain!
DO NOT ATTEMPT TO DRIVE YOUR CAR without a cooling system: with a cooled motor, you need to get this hose fixed and refill your radiator. Also get other engine parts checked as extreme overheating could also cause Cylinder Head and/or Gasket and Engine block cracks.

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).

I have a 2003 VW jetta tdi


You've lost engine coolant somewhere, and need to fill the engine back up with the VW special G12 coolant.

Then find the leak, which will be in one or more of the following places -
Water hoses to heater core, including any other coolant carrying hoses in the engine compartment
Radiator hoses
Plastic manifold bolted to side of engine which is known to leak (have replaced on an '01 VW Beetle, and an '02 Jetta, both members of our family in the past few years.).
Overflow reservoir cracked
Radiator leak.

Reply back what you find. If the engine got too hot, you may need to have the thermostat replaced.

Overheating while idleing


Sounds like your car is overheating, do you have any coolant leaks? If you are leaking coolant possible causes are radiator and or hoses or waterpump. If you are not leaking coolant you probably have a faulty thermostat that is stuck closed and not allowing coolant to circulate into the motor.

Hope this helps
