Lumpy rough from cold? 01039 - Coolant Temperature Sensor Idiots guide

[LEE69]

Clean the prongs inside the header tank, and/or maybe the coolant needs a slight top up?

 

[hinxy]

cheers

I'll try the prongs and i've since topped it up so hopefully one of them will be it. I've had this happening for over a year

Mine is an '04 and it was originally black, the new sensor is not different just the plastic is green instead of black - all new ones should be green i've heard.

As far as I'm aware the sensor is 4 pin (black or green) - if you have a 2 pin one then that is a different sensor you have replaced.

Someone please correct me if I am wrong...

 

[hinxy]

I hope that's not the case it cost me £30 haha

Where i changed it was on the bulk head above the gear box? is that right on the ibiza?

 

[Scottl]

Hinxy, why are you posting about an Ibiza in the Leon Mk1 area?

Anyway, pretty much all the TDIs use the same senor so I can't see why it would be different...

 

[hinxy]

yeah sorry, that was what i thought though. I'm only finding info on volkswagons on the net and the leon's a lot closer to home and there's a lot more knowledge on them in this thread than the other one's i've found

Whats it like for coolant coming out when changing the sensor? Its not going to be gushing out is it, then have to be topped up to find it's air locked? just want to check, lol.

 

[hinxy]

yeah it does gush out. you have to plug it with the new sensor as soon as you can. as for air locking, i just checked the coolant after my next journey and it hadn't gone down that much after topping it up

 

[LEE69]

Mine never gushed out, did it cold in the morning.

hinxy, have you solved your problem now?

I've cleaned the prongs inside the header tank. But the coolant level looks ok...

Someone with an LCR post a pic of their header tank, I want to make sure that the level in mine is ok!

 

[t0m]

Also these part numbers below, are they still the valid one's to get hold of these? Can I just order them into my local SEAT parts department and pick them up ok? Or ebay best bet?

This the right one? http://cgi.ebay.co.uk/COOLANT-TEMP-...35823143?pt=UK_CarsParts_Vehicles_CarParts_SM

Can anyone confirm the above link is what I need for an lcr?

 

[LEE69]

Yeah that's the one )

 

[t0m]

Thanks Lee

 

[t0m]

Just ordered mine. If this doesn't cure the bleeping, then I'll be topping up the coolant, even though I don't feel it's low, maybe it should have a bit more...

 

[LEE69]

If you have cleaned the prongs you should be fine now.
It will only beep if they are dirty or the level is low.

 

[t0m]

Tbh I didn't think the prongs we're dirty in any way, but I've scraped them with a screwdriver.

My coolant level is half way I'd say.

 

[t0m]

Fitted my new sensor earlier, cheers for the guide. Very simple

 

[kwan88]

I tried to find this item on my AMK LCR, do you know if it is the same part and in the same lcoation as the pictures?

 

[LEE69]

I'd have thought so just the diesels it changed location.
