    Unhappy Thermostat fitted in reverse?

    I think 'they' did it wrong on my Disco 2 TD5
    My thermostat is fitted with the side outlet running to the top hose, and top outlet to the pump, and bottom back to the radiator.
    I reckon its supposed to be side outlet to the pump, and top to the rad hose.
    Is this how others have theirs set up?

    I hope you can see the pic. [I found the Manage Attachments button now...]

    Symptoms include the WORST temps on long hill climbs, over 110....
    I can post a graph from the nanocom data if you want a fright...

    If its a LR original thermostat its pretty hard to get wrong as it's marked 'Pump'.

    The flow diagram is on page 26-1-4 of the RAVE manual (available from the Shop here if you don't have it).

    From your pic, yes it does appear to be installed the wrong way around if its a genuine thermostat.
    Cheers

    Yep. Definitely backwards. When I bought my car it came with the thermostat fitted incorrectly and caused similar overheating symptoms. Eventually causing the head gasket to blow

    Here's my incorrectly fitted thermostat.


    The clearly labelled thermostat removed ...


    And the RAVE diagram that confirmed my suspicions.

    Thanks simonmelb and awabbit6 for the insight and info. I'm not going mad after all.
    My suspicions about the thermostat were raised after a drive UP to Ballarat last week. I'll post the nanocom readings in this reply. It reflects about an hour's drive up those long inclines, my armwrestle to keep the temp down, and the 'descent' into the town.

    Then it REALLY didn't like going up Mt Dandenong last weekend - while on my way to officiate at a wedding! Nervous times....

    For all that the truck is still pressing on - no oil in coolant or coolant in oil so far...

    This has been my first question to AULRO - I'm hugely grateful for the responses, and to all who help keep this website going.

    Congratulations That's a great save by you mate.
    I wonder how many more are out there?

    When you fix it , it should run about 82C to 85C up to 35C ambient , if like mine and yours has an 82c thermostat.

    Regards Philip A

    Thanks Philip. I reckon it also says plenty about how much pain these trucks will tolerate. I hope to post more civilized nanocon temp graphs in future! ..

    I took it back today to the people who installed it incorrectly.
    They acknowledged it was wrong and corrected it.
    Lets hope that's an end to boiling the coolant billy.
    Thx again.

    I would write a letter to them advising them of their stuff up and demanding a 1year warranty for a blown head gasket or other heat related failure of the engine.
    All their concern is no good if you lose a head gasket in six months time.

    I had to do this once when I had a rear main seal done on my RRC and they forgot to refill the transfer. Luckily there was about 100Ml in there and it was not destroyed and is still going AFAIK.

    Sorry, that post is not correct, Bob

    Not sure what is meant by this last comment, "Sorry, that post is not correct, Bob"

    If you are not sure of the correct orientation of the TD5 thermostat then here is a correct picture. Note that only some thermostats will be stamped with the word"pump" - so it is easy to get it wrong. It will fit both ways - however if you fit it the wrong way you will have problems with temps and you will notice that it will rest/interfere against the power steering box.

    Be careful with the position of the bypass hose. The large diameter end should not be flush with the junction of the bypass spigot and thermostat body. The metal bypass crossover hose has a raised dot on it - marked with whiteout here for clarification- it indicates where to position the end of the thinner part of the hose.
