What causes sludge in coolant?

Mixing of incompatible coolants can cause theadditives to “drop out” of the solution and formsludge or slime. Contaminated coolant – a badhead gasket or cracked cylinder head can allow oil andcoolant to mix, resulting in sludge. A breach in thesystem can contaminate coolant with transmissionfluid.

What happens if there is air in the coolant system?

If there isn't enough fluid in the tank,air is pushed into the cooling system instead ofcoolant. Some systems can trap air at highpoints in the system. They often have a bleeder valve torelease the trapped air. Trapped air can cause hotspots in the engine, even if the coolant leveldoesn't appear to be low.

Do you have to remove thermostat to flush coolant?

You can remove the thermostat whenflushing the cooling system. Ive never used distilledwater for a flush. Typically, just city water for theflush and distilled mixed with the coolant for thefill. Yes, remove the thermostat as you dontneed to run so long that scalding hot water builds to openthe thermostat.

Why is my coolant reservoir boiling?

Why does air in the cooling system cause overheating?When there's a leak in the cooling system, the pressure of theliquid drops and so does the boiling point of thecoolant/antifreeze. At the same time,coolant/antifreeze flows into the cylinder head through theleak in the head gasket.

Can you pour coolant directly into radiator?

If there is no overflow tank or if the tank does notempty back into the cooling system, then pour thisdirectly into the radiator, making sure not to goover the “full” line. Warning: Make sure to put theradiator cap back on after adding the new coolant andbefore starting the engine.

Can I use coolant without water?

Water is often mixed with coolant at50/50; you can also add anti-freeze if you live in areasthat experience extremely cold temperatures. The reason peopledo not use water alone in the radiator is that it hasa fast boiling point when compared to thecoolant.

Can you just add coolant to the reservoir?
