I've put my sender unit in the top radiator hose. I got an engineering
shop to make up a short piece of stainless steel pipe, add a collar to each end and a lug half way along. I then drilled and tapped a hole the right thread pattern to accept the brass sender unit of the VDO gauge. Need to earth the gauge to neg battery terminal (or body etc).....
too easy. Cut a section out of top hose and insert the new section into it. I carry a full set of hoses/belts anyway, so if there is ever a problem with split hose etc, just need to change things around as you normally would.
Works real good.
Mine is a VDO gauge in celcius.
A word of caution......you'll find the VDO gauge will reflect the TRUE water temp. On my GU, this means watching the water temp vary quite a lot. When the Nissan gauge hits it's "normal" position of just under half way, the VDO gauge is only up to about 50oC. The Nissan gauge will sit at this point whilst the VDO gauge goes from 50oC up to 105oC, before it decides to move up to around half way. From that point the Nissan gauge will go to almost 120oC with the Nissan gauge just about to enter the "H" zone (although it has never got right into the hot zone yet).
As for the idea of oil temp gauge.....I have one of these fitted in the sump and it is good to know what is going on there as
well. However, it is very slow to rise and fall, so I would have to say that it is not necessarily a good "substitute" for a water temp gauge. BTW, don't discount the idea of also fitting a Engine Saver Low Water Alarm!!! The water temp gauge will not tell you if you've blown a hose or something and have lost all your coolant!!!!
