a m8 has told me instead of using water i.e bottled water for the intercooler spray to use windscreen wash as it keeps the intercooler cooler than what water does, is this true and what effect would it make to the intercooler over time, its a hybrid intercooler if this helps.

 

very little difference apart from corroding the paintwork in your engine bay imo

 

Hi,

Washer fluid should keep it cooler as there is normally some kind of alcohol in it to stop it freezing. This evaporates quicker and therefore should cool better..

My spray is contained in the rubber surround on the top mount so hopefully wont touch the paint, should just run down the back of the engine/gearbox...

 

Is it a good idea to be spraying alcohol based liquids any where near a red hot turbo ??

 

Dont do it..

The screenwash can turn scummy like what you see at the bottom of the washer bottle, thus clogging the jets.

 

the surrounding area on the bonnet is covered with a s/steel plate, but i do like my engine bays to be mint.
