Coolant leak overflow

IMO that's too low so you might have a stuck open thermostat, the intercooler should not affect the engine temp soo much... woud be good to check the coolant temp input with a scanner to see the difference then you can have an ideea how to interpret that reading... a friend of mine fitted a sensor like that and the difference was only 6 to 8 degrees between the two so if that's valid your ECT should be around 78 which is not good as it's overfuelled a bit

btw, when your gauge shows 50 is the dash gauge at the middle?... if yes get a laser thermometer and point it to the head where the sensor is and compare readings cos that sensor might be faulty

O that's a little worrying. Normally travel about 15-20 mins to work so not massively long journeys, if I stop and turn the engine off once get back in and turn back on its normally up around the 70-80 mark but then goes down to about 55-65 when started to drive again.

I'd have to see if the local garage is able to plug it in to see about the coolant temp.

When I've done a longer drive it does go up to about 80-90.

I'll see if someone local to me has a laser temp sensor and give that a test to confirm if the sensor is working correctly

that's OK then... though watch the dash as much as you can on a longer drive when your gauge shows more than 50, the vehicle's gauge goes to the middle when it gets a 70*C input from the ECT sensor so if you pick the moment when it's rising from a quarter to half see your gauge's reading then you'll know the difference and starting from there you can calculate the coolant temp in mind

That's a good idea, I'll keep an eye on it tomorrow morning as got a little longer drive to the farm. Hopefully have a better idea once see it climb from quarter to half

So been using the disco a fair bit today moving trailers around and have noticed when I stand still the temp from the sensor goes up and sticks around 70. As soon as I start driving it drops to around 40 so I wonder if it's being effected by wind as when I stop again and turn off. When turn back on its back to around 70.

Anything I could put on the sensor or maybe move somewhere else to see, where about did you say your mate put his?

IMO your thermostat is stuck open, that's a symptom of it... replace that first

I dont know where my friend bolted it as i didnt ask, we spoke only about the readings but i'll check and tell you though you should compare the sensor's reading with a laser thermometer pointed to it cos it seems fubar

P.S... just called my friend, his one is bolted to the coolant elbow(the one with the coolant temp sensor) but IMOthat's not so relevant as it's not supposed to have such big "jumps" between readings
