Dont appear to be any obviouse signs. Engine temp is sat at 90. None of the pipes are particularly hot.

 

[Portoastra]

One of the opcom dongles on eBay you mean for about a tenner? Is that the best thing to get?

 

[Portoastra]

Then that's what I'll do! Ta

 

[Portoastra]

Yes, I do have service vehicle soon come on!!. Wifeys car. God knows how long it's been doing it! I drove it today.
Can it be cleaned if it take it off?
Of tested with a multi meter, or is it a waste of time?

 

[Portoastra]

Does any or know how to check the resistance of these sensors or so with a multimeter to see if they are faulty? They're easy to get to. I've ordered a code scanner for now, but thought it see if I can test them first.

 

[Portoastra]

Agreed. Ive ordered one of the elm327 Bluetooth dongles to see what it throws up. Are they the same as opcom?
Just it will probably take 3 days to get here now so was just wondering if I could test it with me ol meter whilst waiting..I best not buy a new sensor housing incase it's not it. Because if I fit it, I can't return it.

One of these. Worth a go I thought. hopefully it'll show so stuff

 

[Portoastra]

Does anyone know of a good supplier that gives good prices? I called the dealer and they want £160. Are they trying to sell me the whole thing?

I was wondering then..the fan comes on when the car starts up now.

If I were to plug in the New part without actually fitting it on first, whist the faulty one is still insitu, it should stop the fan and confirm the fault? yes???

What's your engine code ? i.e. A16XER,A16LET etc

It says A16xer/20rt1307

 

[Portoastra]

I'd check what codes you're getting first in case it's not the problem but

complete genuine housing

both are the later improved (?) type

Ok,
I'll wait for the code scanner to arrive then I'll come back to you. Thanks for helping.

 

[Portoastra]

So,
I've got two elm327 obd2 diagnostic scanners in the post.
One took a while to arrive so I ordered another from elsewhere.
A black xtrons and a panlong from Amazon.

So, both appear to work and connect perfectly. I am using the torque app although lite version at the moment and so far I've tried 4 other obd2 apps.

Here's the thing.. I get a lot of live data and readings coming from the ecu so they are obviously working but I am getting no dtc codes showing from any of the apps. What's going on??
They say no stored faults or pending faults

Need a little help guys .....

Here's the really weird thing, if I press the clear logged faults button in torque the fan stops running and the service vehicle light goes out but then it comes back after about 10 seconds and the fan starts....


Edit.......

Just found another app called scan my opel that's given me this....screen shot...

Any thoughts

 

[Portoastra]

So can you tell exactly which part needs replacing from that?

 

[Portoastra]

It appears to be in 2 parts though or a whole unit.
Either this...

Or this

How do I know which???

They say the top link is for the astra as well.

 

[Portoastra]

I'll grab one then and give it a go. What's the best way to do it to avoid fluid loss?

 

[Portoastra]

Sausages......pmswl

Good one.

So out of interest, there is a sensor on the other half of the complete unit. What code would that give? it actually comes out.

 

[Portoastra]

Is there a preferred way to bleed air after I've drained and refilled the coolant on the 1.6 j series do you know ?

 

[Portoastra]

.

 

[Portoastra]

Oh. Bit late harry !!!! I guess I can do it again with air bleed screw undone????

I have done said job now. Replaced crummy stat. The Fan does not appear to come on. Hurrah, and no leaks. Thanks gents.

However, I put the exact same coolant back in that came out and Its at a higher level at the moment in the tank by an Inch.....

I'll see what it's like in the morning. No wish to have an air lock...
