i went to fit the sendor for my oil temp gauge but i have rounded the hole you put the allen key in will i have to use a sandwich plate now if so will it still give a good reading cheers

richiewong

Or you could try to use a torx bit instead of a normal allen key, sometimes this will grip into a rounded hole

cheers will give it a try

You could 'T' off from the OEM oil pressure switch.

do you mean the one under the alternator as i have the braided hose for this one for the oil pressure so can i use it for both as it has two bits for sendors

alcazar

iTrader: (2)

That's do-able.

How did you manage to round off that hole, and NOT the Allen key you were using?

I assume you DID use a GOOD QUALITY 8mm Allen key?

peter zippy reid

iTrader: (25)

Yes a good 8mm key the hole was a bit tight with rust so tapped the allen key in place then tried to turn it but it didnt budge just the allenkey spinned now just turns in the hole any info on where to put the sendor now cheers

So Can i use the oem sensor under the alternator to run both the oil temp and oil pressure gauges as i have the braided hose with two fittings on it and will it still give a good reading for both gauges thanks

I used that one to fit the OE sender and the gauge sender as they use different senders, I'm not sure running 3-senders of the same would work.

You could always try a drift and hammer the bung out using the hammer and drift to turn it in the thread, mine wasn't that tight and I suspect it was the rust rather than seizure that caused it to spin. Alternatively, try and hammer in a larger (9mm) allen socket and use a ratchet to loosen it off

peter zippy reid

iTrader: (25)

Cheers jon will try the 9mm key first if it doesnt work can i use the oem under the alternator and i would just be putting the gauge sendors in and doing away with the oem sensor cheers

JonMc

iTrader: (51)

If you bin the OEM sender remember to remove the bulb from the oil pressure warning light otherwise you'll have a moment when you forget the sensor isn't there

peter zippy reid

Ok thanks for the info jon

Just attack it with a chisel and a lump hammer, "Bigarf" style...

Not on a 98 car, you won't.

peter zippy reid

iTrader: (25)

going to give it another try with allenkey socket tomorrow if that fails will just put both into one under alternator

Why don't you buy a sump bung adapter from advanced automotive, much easier & will give a more accurate temp reading.

peter zippy reid

iTrader: (25)

i was told you get a better reading from cylinder 3 under intercooler thats why i bought the adaptor for that one

ianbott

Don't put an oil temp under the alternator you won't get any oil flow so reading will be way off. This location is fine for the stock oil pressure switch and oil pressure gauge sender.

RICHARD J

iTrader: (4)

Best reading for temp is the sump as the sender is upside-down so has better oil supply. Also under manifold temps can cause inaccuracies with No 3 location.

alcazar

iTrader: (2)

That is correct, it is the place Subaru provide, and that for a reason: No3 cylinder is known to run hottest.

Put it there, anywhere else gives low readings.

peter zippy reid

iTrader: (25)

thats what i thought and a checked my allenkey after it spinning on sunday you were right the allen key was rounded so got a socket with the allenkey in it from a mechanic that comes into my work cheers

RICHARD J

iTrader: (4)

Valid point alcazar,but don't you want to know all your oil is hot before you give it the berries & not just the oil near No 3. Also If the bung won't come out on No 3 a sump sender is the best solution.

mickywrx

iTrader: (29)

If I'd saw this thread earlier, would have posted the socket I bought, for you to use/borrow.

Above No.3 is the best place for oil temp IMO, but, if the bung is buggered, T off from the oil pressure adaptor, as Merlin said earlier in the thread.

peter zippy reid

iTrader: (25)

Cheers micky will give it one last try tomorrow finish at one see how it goes or i might just hit it with a hammer and chisel as dunx says then again maybe not

peter zippy reid

iTrader: (25)

so i have put the oil temp sensor into the t-piece off the oil pressure switch but im not getting a reading thought it was the sensor so bought another one still no reading so can it be gauge thats knackered as it was used when i bought it cheers

alcazar

iTrader: (2)

So could you defo not get it into the right place?
Maybe no oil getting to it, not enough to take the oil temperature?

Also, are you sure it's earthed? Try touching a bit of wire from the SENDER outer parts to battery -ve.

peter zippy reid

iTrader: (25)

no couldnt get the bung out even gave it to the mechanic i use tried earthing straight from battery even tried getting the gauge to move by running a wire from the water gauge sensor just to see if it would move but nothing

alcazar

iTrader: (2)

Maybe try the sensor in a mug of boiling water?
My Defi reads from 50 degrees, so it OUGHT to show, if it's working.


If not, duff sensor?

What type of gauges are these again? Does the gauge do ANYTHING? Light up? etc?

peter zippy reid

iTrader: (25)

its a autogauge and the water and oil pressure both work the oil temp lights up and the needle moves to 150 when you turn the ignition on this is the second sensor i have tried and nothing

RICHARD J

iTrader: (4)

Do what alcazar says, if the sensor is Ok then as suggested by others that location is no good. Your only option now is sump bung location as I suggested before. Mine is in a sump bung adapter & works perfectly.
