I hate gauges that don't show temp. Is this too warm?? - Page 2

Thanks! I'll take a look later and let everyone here know what I find regarding temp of lines and numbers on sending unit.
Fan belt has been appropriately tightened.

Thanks again everyone.

+1...check that the sending unit and oil temp gauge are a match. This is common reason for incorrect temp readings.

I better check mine out too. Good thread...

UPDATE:
Took it out, drove it easy to let it get warmed up then drove it

Temp gauge went up to about the range shown on in the first post. Fan belt was tightened, ambient is about 78 F. Put my long Brewing thermometer that goes up to 220 in the oil tank (how much do I love this car?). Got to 180 and stopped. I couldn't see a number on the temp sending unit but since I want to get a headlight relay kit from the sponsor, I'll just order the temp sending unit with that.

+1 too high let us know f you have crushed lines. I would get a IR temperature reader and check the actual temps at the thermostat at the passenger side rear wheel well, the hotter one is coming from the engine.

Mine goes right below that hash mark in the summer. in heavy stop and go traffic, as long as you stay in between the two middle hash marks you are good. Normally at full operating temp, mine will stay at 1/8 inch about the first hash aka 8 o Clock.

What weight of oil are you using?

You have got to have the wrong sending unit. Have a look at the far left side of yout gauge and see what the highest calibration number is. 150C/300F or 170C/340F, etc and order the correct sending unit.

Looks like you found your problem. Congrats!

Is there a 60C/180C option? Those are the numbers I can see on the gauge face to the far left of the lines.

Here's the one I find on the P.P. site http://www.pelicanparts.com/catalog/SuperCat/0806/POR_0806_ELSENS_pg2.htm#item6

I don't see any other option for my car and this is the 85 gauge.

I'm guessing that you have gauge number 911 641 923 00. You probably need sender 911 606 112 00. I'd still take a look at the one you have, first. With a flashlight and a mirror (wrost case, may not be needed) you should be able to read the part number. It's stamped on the sending unit.

This thread hurts...

Fully solidifies that my SC is running to dang hot.

Hopefully, the new t-stat will remedy this.

Better to deal with it now and just resolve it.

Thanks for this, added to the list.

Just got a flashlight in there and it's a 150 C thermostat. Based on what I found on the gauge, it's the wrong thermostat for the gauge. I'll be ordering and updating with pics as soon as the new one is installed.

cabmando -- Have you checked the temp of your front oil cooler lines when the engine's hot (i.e. simply checked to confirm that the front oil cooler lines do get hot?) Sounds like the wrong sensor's the root cause of your problem, but while you're getting this together, also important to confirm that the thermostat that lets hot oil flow to the front cooler is, in fact, working.

Yes, I did the touch test after the test drive with the fan belt tightened. The lines were hot. I didn't put my IR on them to check temp but I didn't want my hand on them long. That really doesn't mean much though as my wife says I have "sissy hands" to many times freezing my fingertips removing AC gauges when I did HVAC I suppose.

If the temp sender is brass, then its early, pre 77 with a 901#. If its chrome covered, its post 77 with a 911 #

So, my gauge showed high... At 10 o'clock, while idling in the garage with the a/c on. The front oil cooler lines never got hot. The oil level gauge did eventually rise to near the top, though. So the engine really did at least get warmer. I am wondering if the thermostat is not working, and/or my server is inaccurate. Where can I find the sender? Is there an article I refer to? Thanks all

Ugh, I was getting the hours on the wrong side, on the drivers side. Oy. Warning the car up now to see how it behaves...

Fwiw, I had the same problem. Gauge was reading high relative to infrared thermometer readings on the engine, oil lines near engine and auxiliary oil cooler lines. I sent my gauge to north Hollywood speedometer. They replaced the oil temp movement and provided a matching new sender for $165 shipped. Went from reading 230F and panic attacks to 185F.

alfisti · 05-12-2014, 07:20 PM

Sorry for the bad autocorrecting. I was feeling the hoses ion the wrong side of the car. I let the car get hit just now, the temp went to just shy of 10:00, and settled back a bit. I felt the hoses on the PASSENGER side (sigh) and they were hot.

Oddly though, earlier in the day, the engine got a lot hotter. It was warmer out then, but not by much. I am still uncomfortable with how hot it got before I shut it off. I will check the sender and gauge combination tomorrow.
