Hi, I'm a new Montecarlo's owner since a week.

I live in France and my car is a 1982 spider grey metallic in perfcet condition 8) .

Look at the photos :

Could anbybody tell me what are the normal values of :

oil pressure
water temp (after how mutch time ?)

I find the water temp is low (about 80 deg. after 20 kilometer) and the oil pressure never grow up 3 or 4 (cold or hot motor).

And I don't understand what the button below the clock is for ?

Thanks a lot,

:wink:

bye

Benoit.

Hello Benoit,
congratulations for the nice car.
It is interesting, that though it's a Series 2, the side mirrors are from Series 1 (Series 2 has mirrors through the quarter glass of the door which are adjustable from the inside).
To your questions:
According to the instruction manual for the Monte the water temp should be 70-90 deg. and the oil pressure over 4 when driving (hot engine). In the reality you've oil pressure slightly over 4 (cold engine, and warm engine when driving) falling to 2 with warm engine when standing, with cold engine it should be about 4 anyway. If the pressure is lower there can be a malfunction in the indicator or the engine is worn (especially the piston rings).
The water temp of 80 deg after 20km is O.K., in normal cases the temp is 70-90 like in the manual, going up to 90-110 with very hot weather and longer driving with higher revs.
Under the clock are the two buttons for clock adjustment, the left one for the selection of hours/minutes/seconds, the right one for their adjustment.
More below under an arrow down/arrow up sign is the switch for leading air to the leg area (when switch is pressed on arrow down). Not that it would really function.

OK, I'm going to go ahead and disagree with that statement about the piston rings.
While engine wear on the BEARINGS can eventually manifest itself as low oil pressure, it is far more likely that abnormally low pressure readings are caused by leakage in the diaphragm of the pressure sender.
I can't tell you what "normal" readings would be, since I have an SAE cluster vs your metric one, but a "rule of thmb" that I use, is that travelling along in 5th gear, the speedo, tach, water temp, and oil temp should all be more or less at mid-travel, or "everything pointing up". This happens in my car at 80MPH. When I take a long trip, I just get it to this point, and I'm comfortable because I can tell everything is within range at a glance.

Hi Will,
The mid travel position of the oil pressure is 4 and 90 deg. of the water temperature so it corresponds with those I said above. And the fuel gauge should be in mid position for a comfortable feeling too :wink:
And yes you're right with the bearings (although a worn or more likely broken piston ring can happen too) and yes you're right that the pressure sender could be the most probable reason (which i meant with malfunction of the pressure indicator but unfortunately didn't find the right words...)

Alex;
My point was just that a bad piston ring won't cause a change in oil pressure, at least not unless your breather is stuffed and you are getting massive blow-by, then I suppose in theory it could drive it up a bit.
I took a look at your website, I like that '82!
I had the exact same crossmember break, which I repaired with a set of plates cut from ~2.5mm steel, with a long stagger so as not to create a stress raiser. Which crossmember did you order from Chad, the OEM type or the "anti-dive" type? Just curious.

Will;
the crossmember was the anti-dive type I think, but the most important thing for me was that it was avaiable and fitted well. Welding on such parts is not really tolerated by the German technical supervising (the famous TÜV).
Nice to hear that you like my silver baby. Unfortunately I've to little time to drive it more frequently in last times.
