Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hello and welcome to Just answer.com, Super mechanic here. About your vehicle.
Does it over heat at all speeds?
Cooling system full?
Pipe leaks? Does it have heat?
yes it overheats at all speeds
i did not check the cooling system but I will check later
the pipe leaks and the car has heat.
This pipe is broken and the antifreeze comes out extensively when the car is on.
The first thing that you want to do is check the cooling system for any exhaust gases. There is a tester for that, that you can gt from Autozone for about $20. It comes with instructions, but there is a blue fluid that is used in it, if the fluid turns yellow, that is exhaust gases.
Block tester available as:
Napa BK.(NNN) NNN-NNNN/p>
If there are any exhaust gases in the cooling system, that will cause more pressure than desired and will allow the engine to burn coolant and/or heat the coolant up too high.
If there are, then there would be an internal engine problem, like a head gasket or head.
