In my experience a LOT of coolant comes out rapido ... and it clear its coolant because its pink! I can't see the pics as I'm at work but I'd advise when you find it and pull the old sensor out to make sure you get the old O ring out.In my excitement (due to aforementioned coolant gushing out) I chucked the old one over my shoulder and tried to ram the new one in assuming the O ring had come out with the sensor. Then spent some time wondering why the new one wasn't seating properly and leaking slightly ...Incidentaly the original sensor was fine - my issue was / is taking a long time to heat up so its going in for a new thermostat at the end of the week.Anyone want to buy and old coolant sensor minus O Ring?

You will need to remove the airbox to get to it. Make sure you remove the coolant cap to release the pressure, then replace the cap before removing the sensor. This stops you losing too much coolant.

« Reply #7 on: January 10, 2011, 05:36:18 pm » Thanks i sorted it now but alot of diesel leaked before and gushed everywhere because i forgot to clip it. Its ok now but can the diesel in the engine bay cause any damage or will it just dry up on its own??thanks guys « Last Edit: January 10, 2011, 05:54:15 pm by ruffrydaz » Logged

Its a different engine so can't say for sure but on the GTI it was the only sensor that was obvious. Follow the line of the coolant pipe from the rad. Logged Sepang Blue S4 BE Avant

« Reply #9 on: January 10, 2011, 05:57:07 pm » Am i right in thinking that replacing this sensor it would get the temp up quicker, and so the air con will heat the interior faster? Mine takes ages, My old mk4 gti heated up really quick. Logged

Next step is to replace the thermostat. New one going in on Friday - will report if it makes a difference. What age is yours? Mines 05 and if this is the problem its either a quirk of the AXX engines or they are at the age where the thermostats are sticking. Logged Sepang Blue S4 BE Avant

I have 05 GTI also, my only gripes with the car are the air con/heater warm up time, and the poor quality speakers,The latter i can fix easy with a speaker upgrade,Do report back when you get the new thermostat fitted. Logged

I did get a new thermostat fitted and it has made a difference - seems to be up to full temp in half the time it used to take - so result there.But compared to other cars (specifically a polo) I drive it does still take quite a bit longer.
