    Optimum running temps

    Hi guys,
    The previous owner installed an after market digital temp gauge on my 88 Maverick. It shows any where from 75 (normal driving nothing strenuous) up to 88 (up hill 32degree day and a bit of gear in the back) I'm just wondering what would be a max temp that I should be worried about? We are doing a trip up to Cervantes next month and will be fully loaded.

    G'day Easy, those temps mentioned sound great to me, others can comment here....:-)
    My only concern ever is where do folks insert their aftermarket sensors and is it true. Hopefully some 88 Vintage blokes will be along soon mate!

    I currently have my after market sensors clamped onto the bottom sides of the outer surface of the top and bottom radiator hoses where they meet the radiator, so metal to metal contact and a buffed up contact surface.. Ultimately if you want the most accurate reading you need direct contact of a very good resistance free transfer surface or better still full contact with the water.. My set-up is a short term compromise, and eventually i intend to cut the hoses and install the temp insert tubes where you can bolt the sensor onto the metal surface with a cleaner/flatter contact than what I have now. If I wanted a more accurate reading i would go with a direct contact RTD, but thats a bit overboard for what I am looking for.

    Friday before Christmas warm day enough so to have air con on all day. 1208 klm from MNC NSW to Yarragon VIC via Monaro Highway.
    05 GU TD4.2Ti
    Max temp was 90 deg C, sat on 60ish normally.
    We have a 6klm climb into the Barrington / Great Dividing Range it gets hot going up there in 2nd. A hot day will show 105 deg C hence the gear selection.
    Cheers

    Not sure about your engine the sensor is fitted to the thermostat housing in ours.
    There is a spare port with a screw in bung that worked really well for us.

    The old zd is 89-91.
    Had it to 93 the other day in 40+ temps.

    Pretty sure the thermostat in the td is 89c.
    So I would assume that is the optimum.
    60 degrees I'd be looking at a stuck open thermostat or not installed at all..

    Yeah it does sound a bit cool. I'd check the thermostat because it should be staying closed so it operates warmer than that.
