Question about 2002 Volkswagen Golf

2 Answers

I have a 2002 VW Golf. Over the last few months the coolant light has come on, and after driving for a while it goes off. When back in the car again in comes on. Where do I look under the bonnet to see if there is a problem? Any advice would be appreciated, thank you.

Well the first thing if you want to check for leaks would be check the coolant reservoir, it's normally along the right or left side of the engine bay with a brightly colored cap.
First check if there is enough coolant, there should be 2 fill lines, lower is cold, the higher one is hot. If the coolant is at the right level then there most likely isn't a leak.
However if it missing coolant;
-Check any hoses or tubes leading out of the reservoir, Take note that there is normally 1 opening or just an open tube leading out of the reservoir or radiator to work as an overflow in case there was too much coolant.
-Check the Radiator for any leaks, or the big hoses from the radiator to your engine
-Check along the engine block for any liquids, If you see any and not sure if it's oil or coolant (usually pretty easy to tell) you can always put a bit on your finger and taste it, coolant is very sweet.
-If you are checking for leaks a way to make them noticable is to pressure test the coolant system, however most people don't have that equipment available at their home so just start the engine and take a look if any liquid is dripping.
If it's not leaking coolant it could be your Cts (Coolant temperature sensor) or a wiring problem

Inside the radiator bottle is the sensor, alot of times can fix by removing bottle and rinse out up side down with garden hose, if don't fix then would have to replace bottle

There is a ticking noise from standard vw golf engine,


It would not hurt to check it but the loss of oil and the loss of coolant are worrying. I would have a compression test done to check the head gasket and head. The tick may be compression gas escaping at the gasket. That would also account for coolant loss. Have a pressure test done on the cooling system to check for leaks. Towing a trailer ( I guess that it had a bit in it) over a long distance at speed ( probably 60 mph or better) places strain on a good engine but if the engine is on par or below then faults appear

VW Golf 2000 1.6 16v automatic. Coolant temp. too low.


Is the heater nice and hot when the needle shows low temp? If the cooling fans turn on and the heater is hot, that leads me to believe the coolant temperature sensor is bad. You should try replacing that sensor. They are only $6 usd here. As long as your check engine light is not on and your fans are running, this will not hurt your car... but this is something you should fix soon if you can. Make sure the engine is cold when you replace the sensor

Yes. If the Service Engine Light comes on it can be a majority of trouble codes that dont even have to do with the engine at all. That could easily be anything. If the thermostat is faulty/old it could easily cause overheating. So could using the wrong coolant, or if the coolant is leaking excessively from places. Make sure you check under the car after is been parked for 1 hr + to see if its leaking. hope this helps!
