1.6 thp temperature problem?

[Mark]

Is it normal when you take the engine in higher revs, the temperature on the dash is going down?

Thank you

how far down ? cant say id noticed on mine after 3/ 4 mins of her runnin it sticks to middle of gauge wether im drivin like hearse or thraapin it ( most the time ) hence the 20 mpg i get

[Mark]

It's always a little over the middle when I drive normal, but when I take it into high revs, after a few seconds it drops a lot. Dealer told me it is the waterpump that is cooling the engine, but don't believe that.

how long u had the car ? and stupid askin this i suppose u checked the coolant level

[Mark]

Coolant level is always low. They can't find the problem causing that. In 7 weeks it goes from max to min

[mattds3sport]

when u say low u mean just below max when shes cold? cant think of anythin else tht wud do this ill keep my eye on mine on way to work tomorrow she always gets abit hot goin up tht darn m6 ill see if mine drops. is it a massive drop or slight ?

[Mark]

With low I mean on min when it's cold. I refill every 6-7 weeks. When I keep it +- 20 seconds in high revs it drops to the beginning of the middle block, so that's a lot i suppose.

:O i keep mine just below max on the ridge of the bottle if u no wot i mean ill hav look wot mine does tomorrow if ur dumpin water like tht id be wary mate keep an eye on the oil make sure it ent goin creamy on dipstick and bottom of filler cap just in case. shudnt hav to top it up tht much tbh. topped mine up once with coolant cas mine ( coolant water)went browny colour n they sed top it up with pink coolant. they didnt touch it in service so it must be ok.

It shouldn't be losing coolant, surely?

Mine's done over 20k miles with no coolant loss over that period.

This isn't normal.. Could be as simple as a loose pipe or something.. but more serious problems which could cause this are a knackered cylinder head / head gasket.. etc

Tell your dealership about this & they'll probably look into it

I have to agree that is not normal, you shouldn't need to top up your coolant. If it's not leaking externally then you are looking at a very serious problem, either way you should get it looked at straight away.

Have the same with my DS3,

Noticed it last summer when driving in Germany. Even with 200+ km/h the temperature didn't rise!
But don't need to refill every 6 weeks. Didn't refilled it till now.

I had the same problem with mine back in January, my coolant would vanish after 3 weeks. I had he water pump replaced and I never lost a drop since. I did however have my head gasket go and my cylinder head replaced so take your pick.

2 months ago they took out the engine and checked everything. There was a brown colour in the cylinder. The told me that's water. They put engine back in the car and problem was solved for a few weeks but it came back. When I tell them about the waterpump they won't believe me.

If there was water in a cylinder then definitely a head gasket or cracked head, they saw this and didn't replace anything?
