Dear Forum,

I have a small coolant leak. I suspect the water pump? Obviously I would like to correctly diagnose it before throwing hard-earned at it!
I have tried looking through an Endoscope, but mine is a cheap one and next to useless...
Can I run my warm engine briefly without the Inlet Pipe, MAF and Breather Pipe, without doing any harm, please?

Thank you in anticipation of your response.

 

Being careful nothing gets sucked in.
And the check engine lite coming on.
Nothing else occurs to me.

 

Thanks as always, Wingrider...
