I have the vehicle listed above and an aftermarket supercharger installed with it, I went to add coolant to the supercharger through its separate reservoir bottle and it wouldn’t stay full, eventually pouring out of the radiator. Now it will not start, it cranks but no start. I don’t know why this would happen or if I did something wrong.

Hi,

I'm not sure which type of supercharger you have, but if the coolant wouldn't stay full, it sounds like you filled the intake with coolant.

I would suggest removing the supercharger to determine if it leaked into the engine.

Let me know. Also, if you could upload a couple of pictures for me to see what you are dealing with, it may be helpful.

Take care,

Joe

Attached some videos, I have a sprintex/innovate twin screw supercharger on my 2013 Scion FR-S.

It has its own separate radiator and was thinking that it went bad or the water pump.

It has a specific place to pour the coolant into so I know I poured it correctly, just the bottle wouldn’t stay full and before I knew it, it was dripping from the smaller radiator.

Do me a favor. Pull the plugs and inspect them to see if there is evidence of coolant getting to them.

Also, check the engine oil to make sure nothing is mixing with it. I looked up the supercharger and believe we could be getting coolant into the combustion chamber.

Let me know what you find.

Take care,

Joe
