However, I am now worried about driving it and doing any damage What should I be checking? If you need anything else let me know. ![]() So I believe the coolant is going around the system. Twice over the past two weeks while driving at normal speed we had a low coolant light/running hot warning come on. I checked all the hoses and they are all hot to touch. Volkswagen temperature light for any of the following reasons: Defective coolant level sensor. I took oil filler cap off and even that was giving off a touch of steam, but I have no idea whether that is normal giving normal operation temp levels. Also might be imagining things, but engine bay seems very hot. I also noticed the coolant level in the expansion tank after a drive is above max line.which has confused me. Temp gauge of coolant is now unsettled going from first line on left to past centre when the light flashes. Light is on more often, but not straight away and it still comes and goes. The warning lamp for the engine coolant will light up if the engine coolant level is too low. I topped it back up, however problem now seems worse. I ignored it the first couple of times, but then noticed the coolant level was lower than min. Oil temp looks ok, but coolant temp was a little left of centre.

You can then have a look for any obvious leaks in the coolant reservoir or hoses, although these may be extremely hard to see. Once the pressure has subsided, you can remove the cap fully, check the level of the coolant and top up as required. Once the engine has cooled down, slowly open the coolant reservoir cap, allowing any remaining pressure to be released.

These leaks can be a serious problem, as they’re not easily diagnosed and easily fixed. Low coolant levels are usually caused by leaks, either in the reservoir or somewhere in the lines. There may be a floating sensor in your coolant tank that triggers the warning light when the level drops. The most common reason for the coolant light to become illuminated is simply that the coolant level is too low. ![]() What causes the coolant warning light to come on? When this process fails, the engine temperature increases and triggers the coolant warning light. In order to keep your engine from welding itself together, coolant is pumped around the engine.
