Testing for electrolysis in new radiator

Post by nickw86au »

Hi guys,

I've just replaced my radiator in my '89 sierra as it had a crack up the top where the hose joined to the tank. (details here http://www.outerlimits4x4.com/PHP_Modul ... 733#899733 ) - I figured that it was pretty old anyway, and so just replaced it.

In the instruction booklet it said to check for electrolysis by connecting the a meter to the -ve terminal on the battery and dipping the +ve probe into the coolant. I don't have a meter that is able to test the small currents involved (0.05V, or 50 millivolts). Is it worth

a) buying a meter to check it
b) going to the local autoelectrician and getting them to check it, or
c) dont worry about it cause it was just a crack and probably caused by shaking around in a swb leaf-sprung car?

Thanks for you replies

nick.

go to bunnings and buy a meter - they have ones for $6 in the electrical section - it is a bit of gear you need.

Thanks guys, I have got one, but it's digital one that only goes down to 200mV... might just get one an analogue one

thats just the range setting, that setting increases sensitivity so you should be able to pick up 0-200mV no worries.
