Testing coolant for bad grounds 900 1991

posted by  someone claiming to be ibs740 on  Fri Mar 20 03:09 CST 2009 [RELATED]

Hi, The FAQ has a procedure listed but doesn't state hot or cold coolant. I notice a huge difference btwn the 2. Cold = .05 VDC & hot was .20 VDC.

Hot is harder to due, run till hot, rag on coolant cap, crack slowly so you don't spray hot coolant everywhere, dip meter probe.

The max voltage you should see btwn battery & coolant was 0.1 VDC. Passes cold, fails when hot.

Anyone please?
