One Common Area Where R53 Minis Leak Coolant Youtube R53 coolant leak. hey guys. just bought myself an r53 to build a track car. one of the first things i noticed was that coolant was disappearing very quickly. was worried at first that it was being burnt off but then found that even with the engine cold and just idling, there was a visible leak present and it looked like it was coming from. Common things that leaked that i've had to replace on my r53 is thermostat housing and water pump. thermostat housing leak will cause the fluid to evaporate from heat of the engine. look for white crust and that will be your culprit. 3. reply.

When it leaks, it dumps ~2 cups of coolant in one go. i was troubleshooting something on my brakes and had the car up on stands for about 3 days. after the first and second day, the floor was dry under the car. came back out the 3rd morning and there was a huge puddle under the car. the car hadn't be run in 2 days, so it wasn't a seal coming.
