Thread: Advice on Engine Coolant Temperature Sensor Change

If the sensor is faulty,
and sending "I am cold" messages even at operating temps,

then yes, I would think that might be a problem,,,

will a nanocom show a faulty sensor in a V8??

Thanks Pedro,

I dont have any diagnostic gear so will try the hit or miss approach first

This is the location of the ECT Sensor (below)



Just did a MAF clean with $11 spray and noticed the top hose (in photo) was very loose and fell off while removing the MAF, hoping this may be the issue. Will take it for a drive shortly.

Hi Simon,
I had a similar problem with my D2V8 when I first bought it.
It used heaps of juice but otherwise ran perfectly until under it lost power when stressed climbing steep hills.This problem continued for about two months until I noticed that the air intake duct was touching but not actually connected to the manifold.
Once I fitted the duct correctly, my fuel economy improved and the D2 powered up the hills no sweat.
You have no idea how relieved I was.
Having never owned a Land Rover before, I was beginning to lose faith. I'm fully converted now though. I wouldn't buy anything else.
Good luck.
Alan

Update,
Well, after the MAF clean and properly securing the top clamp for air intake hose to manifold, it definitely has more torque and less throttle required than before.

My first reaction was amazement gut feel around 20% improvement but then after I calmed down a bit (me, glass half full chappie, not half empty) and around 40klm thrash around Melbourne of slow, crawling and 110kmh thought maybe a more realistic 10% improvement. Maybe I'm more hope than anything else. (psyche profile of a LR owner)

I'll keep my good eye on fuel consump over the next week or so and report back.

I still have the ECT Sensor to arrive (did not arrive today). So may as well fit it when it does (first one in 10 yrs.). Therefore my original question stands. Can the alternator be removed without removing the fan and auxiliary belt?

Cheers

Well the effect of the MAF clean I did was short lived. After a few days the fuel consumption went back up to around 24L/100K

Never did change the ECT Sensor, it wasn't the problem after all.

Anyway, a service and thorough check over did reveal a duff MAF. So gave the go ahead for a genuine LR one at $320 during a service. The guys at AMV fitted it. Something about a reading of 30 thingyjibs now it reads 23 thingyjibs.

After about 100K of urban driving plus today, a good drive down to the Mornington Peninsula with 4 people and aircon on 70% of the time, so far have 300k on half a tank of fuel compared to the usual figure of 350k from a full tank. I reckon this new MAF will pay for itself within 3 weeks

Much more noticeable power up long hills and when pulling away from stationary too.
