Ended up taking it to Ford’s authorised service centre and found the problem after running all kinds of diagnostics.
BHPian giri1.8 recently shared this with other enthusiasts.
My Figo finally decided to throw a tantrum.
One fine evening, the MID displayed an engine overheat warning. I spotted a petrol bunk and decided to stop and get some coolant to make sure no nasty surprise awaits. BIG mistake!
I went inside the store and asked for 5 litres of coolant and the guy immediately asked if it was for my car and if there was any issue. I told him that the car was showing a warning, so I was just going to have it checked. He immediately called a few people and told them to check the coolant level. The level was okay, but I could feel the engine bay being unusually hot. One of the two guys checking the car tried to open the coolant cap. I could see the coolant level raising and told him to take tighten the cap and take his hands off and not do anything. He said that the coolant was spoilt and needed immediate change (repeated this at least 4 or 5 times). Then the other guy told me that in case of any airlock, it would take a minimum of half an hour and they couldn’t assure anything. I understood that they had no idea of what they were talking about and decided to make a move if the engine had cooled down.
Here is the best part. The guy looked at the MID after I fired up the engine and told me that the 36-degree coolant temperature is not high and I should be worried only if it exceeds 42. All this time he was referring to the outside ambient temperature display.
I decided to switch off the A/C and took a less crowded road and reached home safely without overheating the engine. The next day, I did the same and reached Ford’s A.S.S before peak traffic. Left the car with them for diagnosis. After running all kinds of diagnostics they found the thermostat valve was faulty and the radiator had a lot of dust too, which reduced the cooling efficiency. I got the job done under warranty and the car has been running flawlessly.
