Well, i killed her...took her for a blast down the coast, got carried away with the growl...and now she's well hot! For those geordies amongst us, took her on the Bee Hive road and BEEEEEEP STOP - CHECK COOLANT...poo poo, I was in the red. Stopped and she cooled down. Then every time i put my foot down, went to between 90 and the red. Grrr...so I limped home...drove like an old woman (apologies to the old women out there). Dunno what it could be? Never happened before I fitted the CAI...always pushed it to the limits...cylinder head? water pump? Hmmmm...anyone suggest some costs?

Cheers

Sounds like something thats happened to a lot us recently, few threads on th subject scattered about. Your cooling fans may have stopped working. Mine were replaced under warranty but I think its a ?200 bill if its not covered?

Well, out of warranty...sooo...if it's that, ?200. Funny how it's just happened since CAI was fitted yesterday. Possibly pushed it too far? Maybe CAI isn't working properly?

Funny you should mention that, just been having a play, and the plug on the coolant tank is a bit loose. Sure it's something more sinister. Who'd be able to tell me for sure?

Cheers all

No, clearly there are two!!! Should I take it back to Revolution? Or get someone else to look at it...not exactly sure what the problem is as yet.

Nope, only 1 [;)][:p]

Take it back to revolution first, ask them what they've moved about and see if anything has come loose. If that doesn't work, try a local VW specialist with VAGCOM... I think someone said there was one in Blyth? If not, The Golf Centre in Darlington would be able to help out [:)]

Yup there is one in Blyth. Think its called Volkscentre or something. There is another one just off the road that comes up from the quayside towards the life centre, on the left before road bears to left. Good luck. probs a connector loosened

OK. Took her out this morning...drove like an old woman til it was sufficiently warm...then drove my normal style (too fast) down the Seghill road...110 degs...stopped for 1 min...back to 90...then drove to A19...first parking bay, had to stop cos 120 and STOP came on...1 minute again, cool...then by the time I got to the Holystone turn off, hot again, probs 105ish...eventually cooled down as I was driving and finding somewhere to stop. HELP?? OK, we have

1) Coolant Sensor?

2) Water Pump?

3) Cooling fans ?200?

4) Cylinder head?

Anyone give me approx prices?

Cheers fellas and ladies...

do you know if the engine is actually overheating?

coz it could just be the coolant sensor. get that replaced first. its ?25 from the stealers and is a green topped part. this replaces the black 'stock' sensor.

apparently this is a common fault. i'm changing mine today but mine doesn't show it overheating, the gauge just drops back to cold (60, 70 degrees) every now and then and suddenly shoots back to 90.

good luck

i'm not sure if it rules the sensor out or not. i know other peoples sensors on here have flipped all over the place and as the sensor is hooked up to the ecu then if it reads hot it will warn you on the dash.

can you see the header tank bubbling when it says its over 100? the coolant will raise the boiling point slightly but you should still see some sort of action.

does the engine feel overly hot when it says its over 100? (leaning in the bonnet?)

Header tank? The coolant level rises and I can hear a bubbling. Yes, engine feels hot...it's my first car, not sure what overly hot is tho :)

I know water pumps go on the T's, could be that, or a knacked thermostat, or dodgy sensor. Do you know anyone with VAGCOM to check the DTC codes?

Sadly I don't. Apparently a few local VW Specialists tho. So will check them out on Monday.

Bit of a sickener like!

hmmm... i'm not sure how else to check the temperature, other than sticking a temp probe in the header tank! lol.

(header tank being the reservoir where you're coolant leavel is if that was what you were unsure of?)

change the sensor anyway as it needs changing if it is a black one. if this doesn't solve the problem then there is a problem with overheating.

Get yourself a Haynes manual first

1) Coolant Sensor? - you can check this using a volt meter by measuring the resistance (which I don't know what it should be, you should be able to find out) Using VAGCOM there will be a fault code if this is knacked.

2) Water Pump? From cold, take the header tank cap off, and run the car, if the pump is working the water will be moving etc.

3) Cooling fans? When it get hot the fans will run unless the sensor is knacked, check all the connection / connectors

4) Cylinder head? Oil mix with the water, you can tell this by lookiung in the header tank it will be a white colour,

Please amend or correct me anyone with these simple checks
