QuestionI have a 2002 Range Rover HSE with less than 38,000 miles on it. Over the last two weeks both the "service engine' light and the 'Climate Control server light (read: book)' came on at different times. Both of these warnings disappeared and there has been no evidence that there was any problem with the vehicle. However, on the way home from work yesterday the display began to show that the RR was overheating. The temperature would rise and fall seemingly independent of external factors. I stoppped at the nearest gas station and steam/smoke came from the engine compartment for a brief period (1 minute). I then purchased anti-freeze and mixed with water to fill the coolant level.
The system took roughly 3 gallons to fill. Since that time all apppears to be normal in terms of heat levels.
What could this issue be? Could my sporadic engine warnings all be related to simply low coolant levels.
Your advise is appreciated.
AnswerI can't calculate in gallons :)
So, in the cooler system there are 12 litres of coolant. At least 3 litres needs to miss, for overheat at normal enviroments.
When the engine gets to the normal operating temperature, try to grip the big tube from radiator. If it not too hard, then check the radiator for cleanness (between the reeds).
If OK, then fill with coolant to the top (at hot engine), and check level about 500 kilometres later.
The heating control module's fault can only be diagnosed by T4 diagnostic system.
