3.6 temps

[Horse_Apple]

Runs around 80c for water and 60c for oil in normal driving.

Once in traffic it rises to 95 and 85 respectively.

There does seem to be a smell of 'heat' from the engine at that point as well.

Basic Q is what is the norm and do I need to be concerned? What are the danger levels?

[rebelstar]

Sounds quite normal to me.

[hollowpockets]

normal, my car pretty much stays around the 90-95 mark,

[t350chunder]

Sounds about right to me.

This time of year...
In London mine runs at about W:92-99 O:85-90
Out and about W:<80 O:60-70

Last year had a problem with a leaking rad. Unless you have had the expansion tank upgrade the car will let you know when it gets too hot. Hisses at you a bit and blows steam in your windscreen

I've heard it's two stage fan kicks in when the water hits 92 and 96 (1st and 2nd fans). I've been caught in some lengthy slow moving traffic jams, seems to be fine...

Hi all

Funny this one, i was gonna ask the same myself. Took my t350 for a sunny daytime blast yesterday and it was idling around 99 to 105 then on journey it colled to 90 to 95. Fan comes in nicely. No smelly hotness though. It once got to 115 sitting in traffic and warning came up but as soon i got away again it cooled to 89 to 90. This dont sound right to me!!!! Any ideas? Oh and had heating on flat out on hot and it wasnt blowing hot air, but all of a sudden it would for 20 secs and it would cool to 85 ish. Then no hot air and it would go to 95 again. The same for many times over on 1 hour trip? Again dont sound right. Sounds like thermostat dicky. What do ya think boys?

Sounds to me like you need to bleed the cooling system.

There are two bleed valves near the radiator. They are hex bolts basically, don't do it when the car is up to temperature! You should get an amount of air leaving the system, be a bit careful of the washers when you do this... Its quite easy to loose them into the engine bay.

There is also a third one at the top of the engine. If you take off the air box (again just some hex bolts) and locate the water temp sensor, this is a good one to do as it is near the top of the cooling system where air can get trapped. You will need a spanner to get the sensor off.

Always worth topping your water up, running the engine with a few revs and re-checking after the first go (air gets trapped if a few places).

But what you have described definitely sounds like air in the system. You should also find it uns a bit cooler (the temp's you are getting sound a bit hot)...

Perhaps check also that the connector on the temperature sensor has not corroded - mine did a couple of years ago and the fans did not come on at all, but perhaps your sensor contact is intermittent? 115 is IMHO too high to be considered normal.

Think I've worked out what the smell may be when it gets hot to about 90. I had a full respray on the car to change its colour and so it may well be the new paint giving off the fumes, there is certainly a chemical element to the smell as opposed to oil/dirt etc.

[extremekiter]

Thanks all again!!!!! Cheers Chunder ill give it a go over xmas. I was gonna take a ride to Stansted TVR but hopefully shouldnt have too now. Your a star!!!!! Cheers mate........... If i get a few probs ill give you a shout if ya dont mind.

Ill give the temp sensor a look at 2. Might well b corroded but the fans do cut it fine anyway. But thanks !!!!

Here's a new question:

Noticed yesterday while running back from the country that the oil temp won't go above 40 for the duration of the journey if driving normally on an open road.

I saw this the first time a week or so ago when getting onto the motorway after crawling through town, the temp dropped from 60 to 30.

I'm guessing that once the engine is warmed up evenly then running it at these lower temps shouldn'be really be an issue but would appreciate any views.

TIA.

Mine does this, in the winter the engine is just cooling down far quicker with all the cold air blowing in when your on the move, bringing the oil temp down. Once in traffic it creeps up again...

The manual says that you shouldn't boot it until the oil temp is 60+ so presumably when it cools down you should take it easy again ?? Thats what I do anyway

Cheers Scotty,

I've been thinking about this today and I'm going to have a look under the bonnet this evening as I suspect that the solution is that the sensor is in a stupid place.

My theory is that they've fitted the sensor to a pipe, pot or tank off the engine and probably at the front of the bay, thus when you ram a load of freezing air in the front you get a false reading.

It just isn't possible for the block to cool like that.

[t350chunder]

I've noticed that too... Let me know what you find!

Thanks, Rich...

I am fairly sure the oil temp sensor is actually screwed into a place where the oil is in contact. This is only based on my dealer telling me an oil leak I had was because the oil temp sender was loose so I assumed it is in the sump or somewhere similar ??

[hwassall]

The sensor is on the oil catch tank, not the block and so doesn't give an accurate figure at speed in cold weather. There is a thread on here somewhere where someone used a piece of plastic estate agent sign across the front of the oil tank to reduce the affect pf the cold air flow on the oil.

Very interesting...where is the oil catch tank ?? Does it give an accurate reading ever then ?? given that information

I probably have the wrong name for it. It is the alloy tank at the front of the engine bay with the alloy cap and dipstick. IIRC the temperature sensor is on the right hand side.

This I can confirm. after scrabbling around in the dark last night. Right place for the tank, silly place for the sensor.

cool cheers lads, what a bloody stupid place to put it
