Bill F looking back on my physics that I took too many years ago to mention I remember something we should all remember expansion and retraction.

Check the coolant when it is cold .

NotLegalAdvice Hey everyone,

My check coolant sign keeps coming up for my '16 Discovery Sport HSE.

I checked and the coolant is fine. The sign goes away after a while. Why do you think this is happening? Perhaps the weather has something to do with it? It's -15C and snowing a ton.

Any assistance would be greatly appreciated. Thanks!

Bill F If the hose ruptured it is not likely the water pump is the problem. The solution from Land Rover to add more coolant after the air bubbles have worked their way out of all the crevices seems reasonable. Somebody is always mentioning things that may not be the problem with your vehicle. Add 200 cc of water and if the light comes back on, worry, or waste a day going to the dealer.

I had the thermostat in my Merc changed out and it took several weeks for all the air bubbles to escape. I had an Audi that had a special valve designed to bleed the air from the system but was the only car I have owned in over 50 years to have a bleeder valve.

amy_alley1 Hi all,

I am having the same issue. 2017 Disco sport with 24k miles. Last month when starting my car there was an explosion under the hood and green liquid dripping from the front of the engine...towed to dealer...was told by LR it was a coolant leak and the hose was replaced, leak resolved. Yesterday the low coolant light came back on. Taking it back to the dealer. Any theories on what exactly is the issue with this model? Someone mentioned a water pump leaking, is this the culprit????....I will say the recommendation by LR to top off coolant is not acceptable.

DocJuma It looks like electronic system of Land Rover Discovery Sport is very poor designed. I got 2015 Land Rover Discovery Sport and engine maintenance light constantly coming up , took it 6 times to garage and no one knows what it is? Garage replaced 3 parts and the same problem.

Bill F AWeiss seems very lucky. In the 55 years I have been driving I have had to add coolant to everyone of my cars. Only a very few because of leaks. If work is done on the coolant system it sometimes takes weeks to have all the air trapped in the system work it's way out. On the Disco after over a year of driving the low water light came on and I added maybe 200cc of water and nothing in the last 3 years.

Not sure about the Hills of West Virginia but I never have problems with the sensor in the Rockies and the dealer probably is wrong there.

6 times in the shop in 10 months for coolant issues

I purchased a 2018 Discovery Sport December of last year (2018). Within the first week the coolant light came on. I called my sales man and he had me swing by. The service manager added water to make the sensor turn off. A few weeks later the light came on again. I took it back and they again added water and told me "evaporation was normal". A few more weeks goes by and the light turns on again! I book an official service appointment and they kept it for a few days only to tell me they found no issues. Another month goes by and the light comes on again. They keep it a few days again then say nothing was found, but that they put dye in the coolant to see if there is a leak they couldn't detect. I think this was a bunch of bull because coolant is already colored. Of course a few weeks later the light comes on again, so I took it to a different dealership. They keep it three days again and said they found a small leak. Everything went great for about 5 months when the light came on again. I took it to the last dealer and they again said there was no problem found, it's been hot and I just need to add water. In my 24 years of driving/owning cars I have NEVER had to add coolant to a car. They tried to tell me that the sensor is in a bad location and that driving on a hill could set off the sensor. That's CRAP! I live in Columbus Ohio, not the hills of West Virginia and even if I did live in the hills I still don't think the sensor should be set off every few months. This is not normal.

[email protected] That happened last year on my 2016 DS. Turned out to be a slow leak from the water pump. Replaced under warranty the next week.

Bill F Add some water to bring it up above the min level and it should clear itself. If the level drops again then phone the dealer.

suebee My 2018 Sport has under 9K miles and the low coolant light came on today. I was about 5 mins. away from home. I checked the level when the car cooled down, the fluid is below the minimum level line. I'll need to get it towed to the dealer and try to arrange for a loaner car for the weekend. This is very frustrating to have non-normal issue already in a car that is 7 months old.
