Engine and engine cooling: cooling system
- What is wrong
- Vehicle description: passenger vehicles. A malfunction or failure of a coolant system component, such as a thermostat, water pump, or fan belt, can result in significantly increased coolant temperature and system pressure. If the indications of a critical overheating condition is not noticed by the driver, it is possible that damage to, or failure of, a coolant system component could occur.
- Risk
- If a crack were to form or a seam were to separate in the heater core end piece, hot coolant could suddenly be expelled, increasing the risk of personal injury to a vehicle occupant.
- Remedy
- Dealers will install a new design radiator cap to control pressure and provide greater coolant overflow in the event of overheating.

What 1990 BMW 735I owners say
Most recent owner complaints, unedited.
This mustard colored module causes the computer to warn the driver of a failed parking light and/or tail light when the headlights are turned on. Every time these lights are turned on, this module sends a signal to the driver. Upon inspecting the lights when this warning occurs, the lights are fully functional. However, about one third of the time these lights (the front left parking light, the rear left parking light, and the right rear marker light in the bumper) actaully fail. These lights fail even though their fillaments are still good. What is causing this problem is a cracked solder joint inside of this mustard colored relay.
