Engine temp?

Richard tea

Im not sure if its a problem or not so ill put it out there anyway. My 2005 vw Touran engine temp reached 90 degrees after only a few minutes driving, It stays at 90 until I switch the engine off. Is this normal? After an hour long journey the engine is quite hot to the extent I can smell plastics from the engine area. My Peugeot reaches 70 degrees and would rarely hit 90.

Is your rad fan coming on?

Is 90 in the middle of temp gauge, if so it's normal.

Your VW is grand, it's your Peugeot that has a problem

Richard tea

Thanks lads. The missus has the car out at the moment so il check it later. I think the 90 degree mark is in the middle alright

Thermostat stuck open?

90 is at the middle of my temp guage and that's exactly were it always sits when driving.

VAG tend to fudge the temperature gauges a little so that 90 *C on the gauge actually could be anything from about 80-100 *C. It prevents the needle from dancing around the place due to the normal variations in temperature and freaking people out.

SO they rig them to stay at 90 ? lol Isn't theneedle going to jump around anyway? I've drove in conditions from -16 to +35 (not on the same day) from driving up the alps to driving the ring out of it on the 'ring and i've never seen a needle budge. If there is one thing VAG to well is make and engine block that can hold it's coolant and temp lol

Richard, modern engines tend to keep the temperature at the ideal working range - which is indeed around 90 degrees for most. Sounds like your Touran is just fine.

As for the Peugeot, what year is it? Some older cars will kind of "cool down" on open roads depending on the cooling system design. I had an Alfa 155 that dropped to 55-60c driving at motorway speeds, and that was how it worked.

Yep if you watch it closely it slowly makes it up to approx 80c and as soon as it gets there it jumps to 90c and stays there

Same here,

once warmed up it never budges, mine always rises to 89*C and stays there regardless of driving behaviour or environment.

Takes about 5 mins to warm up on a warm day and 10 mins on a cold day and I drive nice & easy until warmed up, by that time I'm nearing the M11 and getting ready to gun it. :cool:

There is a "dead zone" on many cars just to stop people freaking over minor fluctuations.
The only car I've had that showeded minor fluctuations was a late 90s Fiat. (although maybe thats not a good example, had a few issues!)

I bet if you check obd coolant temp versus displayed temp you will the exact same needle position for range of temperatures.

Big difference between small fluctuations and the needle dancing around the place

True, even with ultra accurate measurements with no deadzone you're not gonna see all that metal oil and coolant dance around in temperature terms. Be it VAG or fiat.

We're going off topic!
