the water jet that blows water onto the intercooler seems to be ok but looks like the pipe is blocked the pump seems to be working fine as theres a sucking from the water resovoir in the boot.

so should i just blow it back from the hose in the engine bay with a air line or is there sum sort of special way to unblock this thanks

 

Remove the pipe from the nozzle and hopefully it will blow it out.

 

but this will cause no problems to the pump?

 

It will only flow for a short while so should be okay. If you try blowing from the pipe in the engine bay to the bottle I am not sure if the pump has a one way valve so you may not be able to. Other option is remove tank to allow you to disconnect pipe form the pump and then blow through.

 

cheers mate thanks
