Thanks for your help!!!
I have a confession.......it was dark last night and I put screenwash in the Engine coolant!!!!!! I stressed like mad. However, after looking on the net I was re-assured that .... I'm human and not the only one to have done this. ....and most important of all that no harm has been done to my engine!!!! Unfortunately it won't clean it but more importantly it certainly won't harm it!! So now the light is out and I have bubbles coming from my radiator!!!!!!!!!!
Now that IS 'cool'. :wink:
