Weepy

This is another instalment in the series of me profoundly disagreeing with trained professionals in areas where I have no experience.

At the beginning of the year I got talking to a rowdy bunch of rough blokes at a burger van. I was introduced to the theory (with which I have no reason to disagree) that one of the main differences between married and single men is that married men don't have motorbikes and car parts indoors. Its easy to think that married men are too polite to take oily vehicles into the house but perhaps it's the other way around. Maybe the sort of men who would rebuild an engine on the dining table don't find themselves with the opportunity to propose.

Last weekend the man from Caterham told me that my radiator core was weeping. I can see the coolant residue on the fins but I think it's coming out where the top hose joins the inlet. I work with an ex marine architect and he taught me the groundbreaking theory that water doesn't tend to run uphill. As I can see coolant residue above the core I'm pretty confident that that's not where it's coming out.

He also told me that I can make my own pressure testing rig at home, and he was right.
This is a bicycle inner tube fitted over the inlet and outlet and some old heater hose to support the pressure. It works well up to about 10psi.

I then dropped the whole thing into the bath and looked for bubbles. Don't worry, I washed the worst of the dead flies and the grime off (from the bath) before I started.

It's probably a good thing that I live alone, but I'm now confident that the radiator itself is intact.
