Can I ask if the coolant level goes below the "minimum" mark on the expansion tank before you top it up? There needs to be space in there because the coolant expands as it warms up. If the tank is overfilled when cold the coolant will just be expelled - usually through a rubber hose near the top of the tank, as the engine warms up.

You could check next time to have to add coolant by starting the engine and then just sit and watch it for a few minutes to see if / where the coolant is coming out.

The place to add the "stop leak" is where you add the coolant when you are topping it up. Final question - is there any white gunge like mayonnaise inside the oil filler cap? That would be a sign that coolant is getting into the oil system.

I hope this helps - if not please give any further details and ask again. Thanks.

I have a 1998 vw new beetle. The check engine light came on and not sure why. The car seems to be running fine. Last week we replaced the tensioner pulley and a new belt. Now I have the engine light on....

Some auto parts stores scan check engine lights for free. If you can get the code, and tell me what your engine/trans is in the Beetle, I can help narrow down the cause of the check engine light.

03 vw beetle, battery is dead and door key cylinder is broken and just spins. How do I open the door or hood? Keyless remote will not work with battery dead?

Wow. You have a real problem here. I see a couple of choices for you.
#1 Can you get in through the passenger door or the trunk?
#2 You can break a window that will allow you to reach the door locks.
#3 You need a membership in an auto club or a friend with AAA. They will open your door using a 'slim-jim' or a 'wonder tool'. This will use up 1 of the 4 emergency calls that are allowed per year.
I would suggest the last option. Just ask around at work or check with your neighbors. You cannot 'roll-over' those 4 uses per year. It's use 'em or lose 'em. Many people will share their membership, if you simply ask. Good luck

I have a 2003 VW Beetle - love the car except I have to monitor the oil every month - it goes low - no leakes per mechanic both dealership and private. Was told by VW mechanic that Beetles use lots of oil....

Sounds like an isolated problem. While it's true that VW Beetles use a lot of oil, it sounds like you are loosing an abnormally high amount if your having to add oil every month. If it's not leaking out it has to be burning out through the engine. A good indicator of loosing too much oil through the engine is a white smoke coming from your exhaust.

Also, be certain your using the SAE 5W-30 oil that's recommended by VW.

My 1999 VW Beetle losses antifreeze.

You will need to look all over the engine with a good light. If it is leaking somewhere, look for pinkish residue. Since your antifreeze is pink, it will leave behind this color. When you find it, that will be the source of your leak. It is probably small right now and evaporating before it hits the ground is why you don't see it.
