There is brown sludge in radiator what is the cause do you think
The sludge is due to rust in the cooling system due to lack of maintinance, you will need to have the system flushed, you will need to remove the upper and lower hoses from the engine and run the water hose through the radiator first, you will need to do this a few times, then the next thing would be to remove the thermostant and run water throught the engine, the water will go in from the top, star the engine while water is flowing through the engine dont let engine run to long it will overheat, let it run for about 2 min at a time, then with the thermostat out install the housing and connect hoses, pour some cooling system cleaner into radiator and run engine for about 20 min, then flush out again, then refill and run again with water and then drain it out and fill with coolant, make sure that the coolant is mixed 50/50 coolant and water, you will notice that after it runs for a while it will turn brown again due to build up in radiator and engine, there is nothing you can do about that but atleast the coolant will be good and stop the internal gaskets and radiator from rusting out, you will what to do this again in 6 months to get it cleaner. good day. hope this helps.
