Either the water pump is bad and water is leaking out of the weep hole on the bottom of the water pump while the engine is running OR you have a blown head gasket that is letting coolant seep into a cylinder and it is being burned by the engine. Have another car follow you on the highway while doing about 60 MPH or 100KPH and then floor the gas on the car and see if the car following you can see any smoke or mist looking exhaust coming from your car. If they do see mist or smoke coming from your exhaust, you most likely have a blown head gasket that is allowing coolant to be burnt by a cylinder.

If you can't afford to repair the car at this time, if you keep your eye on the coolant level and refill it when it needs coolant, you could continue to drive the car until you save the money for the proper repair.

Much good luck.

I have a 1999 jetta that pukes out antifreeze after driving it. It will do it after about 4 or 5 hours after driving it. It never over heats. This last week, I noticed the antifreeze running out of the motor on the left side. We are not sure where it is coming from. We bought a water pump thinking it was that but discovered the water pump was on the opposite side of the leak. Do you have any suggestions.

Should i drain the cooling system on my 2001 mercury sable

Every 5 years,you really should,if you put more than 10,000 miles a yeasr on it.
Check the coolant for freeze protection every year and every time you add anti-freeze or water after you've run it for an hour or more(to let it mix thoroughly into the expansion tank).
If the coolant has been in there and has a dirty look, even if it tests good, you should do a flush.
Your heater has a bypass hose above the hoses that connect to the heater core. So just take a pair of clampin end vice grips and clamp off the hose before it enters the heater core(this is if you have a great heater and KNOW the heater core doesn't need flushed).The block on your car has a drain plug(allen head,I believe)on each side of the block down low towards the front.You can remove these to do a great flush or you can just keep flushing water hose water thru the radiator. The sequence is this...........
(1) Drain all you can out of the radiator(there''s a big plastic cover under the car you need to remove to get to it on the driver's side radiator).
(2)You can remove the engine block drain plugs or not,IF you really flush it well.
When you are satisfied you have most anti-freeze replaced with water, you start the car with the proper level of water in the expansion tank,and add your flushing agent.Of course follow its directions, but after running the car for a few minutes, be aware you may need to add more water as the thermostat opens.
(3)After draining out the dirty water,let the engine cool for at least an hour,then fill it with HOT water to prevent any cracking of block or heads.This also you drain out and let the engine cool all the way down.
(4)NOW you're ready to fill with full-strength anti-freeze(Prestone or equal quality)but don't use the 50/50 strength.Becausde your engine has water in it, you will blend automatically.
(2) Two gallons of antifreeze will do nicely to give you a 60 anti-freeze to 40 water ratio or thereabouts,and that will test to greater than 40 below zero F. don-ohio

The radiator warning light blinks red on startup, what kind of radiator fluid does the vehicle take? 2005 VW new beetle

VW have their own spec anti freeze/coolant, but any good quality upper market anti freeze can be used and some will even say that they are recommended by VW. Follow the directions on the container for mix and dilution.

Where does antifreeze go

Antifreeze goes into the radiator. There should be both a radiator cap and also an overflow reservior. Top off the radiator and fill the reservoir to the "max fill" line. NOTE: DO NOT remove the radiator cap when the engine is warm. You'll get burned

The procedure to replace radiator on 1999 VW Jetta is as follows:--- **Locate and remove the drain plug on the bottom of the radiator, and let the engine coolant drain into a resealable container. Then unplug the electrical connectors from the coolant fan and thermal switch.
**Then carefully detach the release lever holding the front bumper, and take off the radiator grille. Remove all bolts holding the front bumper and take off the bumper. Disconnect the temperature sensor connector and if necessary remove the spoiler.
**: Unhook the quick release couplings holding the coolant hoses to the radiator. Removing the screws securing the headlights and disconnect the headlights. If your Jetta is equipped with A/C, unfasten the A/C mounting bolts and the condenser bracket bolt on the left of the radiator.
**: Remove the radiator mounting bolts and slide the radiator and fan by sliding them downward. Don't disconnect any refrigerant lines, if your Jetta has an air conditioning unit.
**: Take the retaining clamps off the refrigerant lines and remove the bolts securing the refrigerant line from the side of the radiator. Be very careful that no hoses or lines are stretched or bent. Swing the radiator down and remove it from the vehicle.
**: Replace the radiator and replace and reconnect all engine and electrical components and the fender and bumper in the reverse order.
**: Then carefully fill the radiator with a mixture of half distilled water and half engine coolant. Start the vehicle and let it run for few minutes with the radiator cap off, in order to bleed air from the lines. Check the fluid level and top it off if necessary, then put on the radiator cap.
------Its done.

My 96 jetta gets hot & beeps a lot during stop & go traffic

your anti freeze is worn out and corrosion has built up and is clogging/blocking flow, solution is to drain radiator, fill with water and radiator flush (found in auto parts store) follow directions on flush bottle, change thermostat while system is empty and refill with new anti freeze mix. for more detailed help suggest a chilton's manual for your car available at auto store around$25 and guides ou through most repairs
