I poured bug washer liquid in my temperature gauge. What could happen to my car? The bug washer liquid is pink. I wasn't looking and there was another container that had a pinkish looking liquid substance. After I realized my mistake and the liquid was already poured into this container, I looked at the lid and saw something that looked like a thermometer with a tree-like lines surrounding it.  What could happened? should I take it in for a check up? Thanks

The heater core is leaking fluid inside the car. The heater core needs to be replaced. Feel the liquid it should feel slightly sticky and have a slight sweet smell to it. Open the hood and look in the antifreeze reservoir. The liquid should match color and consistency.

Coolant Temperature Gauge
The coolant temperature gauge is also operated by 2 coils. Battery voltage is applied to both coils. One coil is grounded directly and the other coil is grounded through the engine coolant temperature (ECT) sensor. The ECT has 55 ohms resistance at 127°C (260°F). The resistance becomes greater at low temperatures. The resistance is approximately 1400 ohms at 38°C (100°F). This causes the current through the sensor and one coil to increase as the coolant temperature increases. This moves the pointer.

Probably the coolant temp sensor . have you tried that ? No, relay in the circuit .

Usually the problem with no heat and overheating is low coolant, thermostat, or a faulty water pump impeller.
The radiator may not be full of liquid coolant, or the pump may not be moving the coolant thru the block.

vw beetles do not have a temp gauge so instead when the car is cold the light is blue at normal temp no light when over heating or low coolant red light and it beeps, you need the right coolant for your vw it is pink in color and some napas have it (Not DEX Cool) and you probably have a coolant leak, usually a plastic flang at rear of cylinder head goes bad

The blue light is only supposed to indicate low engine temperature, reminding you to go easy on the engine until the light goes out.
The flashing is either for low coolant or for overheating, and it sounds like you are having a low coolant problem.
If after you add coolant the lights comes back, you have a coolant leak. The most common place for a leak is the coolant flange on the end of the cylinder head. If you take the engine cover off and look at the area where the transmission meets the engine, you should see either pink coolant puddling or pink crusty residue.
It's also possible to have other leaks from the radiator, heater core, water pump, etc. The nice thing is that with the pink coolant it will leave a trace of pink residue leading to the leak if you take a good look around with a flashlight.

It sounds like you have a partial blockage in the cooling system. If liquid gasket material was used with the pump an or thermostat replacement some of this material may be in the coolant path. Other things to consider; your thermostat is the wrong temperature, you got a bad water pump. Take the radiator off and start the car when it is cold. Let it idle and watch to see if coolant begins to circulate after the engine reaches the operating temperature to be sure the thermostat is working correctly as well as the pump.

You can use any windshield washer fluid. I highly recommend Rain-X Bug Remover Windshield Washer Fluid. It works just as advertised and keeps bugs from sticking to the windshield. You can buy it at almost any auto parts store, WalMart, K-Mart, etc.

I have seen this happen to a few cars when they were running REALLY low on coolant (anti-freeze) AND/OR had a major air pocket trapped in the cooling system.
Heres whats going on:
The gauge is driven by a temperature sensor that sticks into the cooling system. When your really low on coolant, some times the temperature sensor is exposed to air, instead of liquid coolant and the temperature of the sensor drops. As your driving around sometimes liquid coolant touches the sensor and the temperature reading will spike again to normal readings or to an even hotter reading then normal (because what little fluid is in the system is not enough to maintain proper temps).
If you recently filled up or topped off the coolant from a low coolant situation then you may have a major air bubble locked in the system, although this is far less likely in the small Sentra cooling system, but you never know.
Lastly, the sensor itself or the plug into the sensor is loose, broken, or shorting. You or someone you know can try to locate the coolant sensor for the gauge and see if the connect to the sensor is loose or the wire have become damaged, giving you readings all over the place.
