    Default renault 10 wtaer temp guage question

    Hi

    Just wondering if anyone knows where i might get a water temp guage for an R10
    Are there tips re where to locate the sender?

    Also interested whether anyone has advice on fitting an electric fan to an R10?

    I've had one for many years in ours. It is a standard Smiths one, with the electric sender unit fitted into the top radiator hose. The fitting in the hose has never given trouble. The main thing it has proved is that the R8 has never overheated!

    The benefit, I reckon, is that you do know the thermostat is working (more to the point, you know when it is NOT working). The only time it has even tried to overheat was carrying a lot on a roof rack, and disrupting the airflow to the grill on top at the back.

    Rob,
    What tools do you have? First buy the gauge that you will be using, then see what kind of fitting does the sensor require. New stuff has 1/8 NPT thread 90% of the time. If you have that size tap then drill and tap in the plate at the back of the head if you can undo the 6 bolts. This is the easiest and 2 nd best. On the pump housing, just below the hose outlet is a blank area where the factory installed the Gordini sensors. You can utilise this blank but make sure when the housing is removed that you have enough flesh to tap, or else you will need a bigger tap to go into the body of the pump and then use a reducer to get back to the 1/8 NPT.
    I am not sure if the type that JohnW used (through the hose) is still available.

    John, does yours go through the hose? With a plate that seals it after penetration?

    Regards

    I know this could start a whole new argument, but I believe the plate on the end of the head is at the front of the head, and the water pump is at the back!
    That matter aside, I bought a Trisco temp. gauge from Repco (and oil press gauge), which came with an adaptor for different size threads.I drilled the end plate to the smallest size and used the adaptor as a nut on the inside of the plate, with a small amount af high temp. gasket sealer, just in case. Still working o.k.

    I forgot to add, hose fitting kits for mounting of temp. sender units are readily available on Ebay.

    Hi Frans.

    Exactly right. There is a fitting that clamps neatly around a hole made in the hose, fitted with a female thread into which the sensor screws. Of course you need to earth that assembly separately.

    It hasn't shortened the life of the hose at all, nor leaked at all. I've only used 2 or three hoses on the car in 40 years, come to think of it.

    Cheers

    John
