Oil/Temp light...
Posted by: Johnnya101 ()

Hi guys,

Finally got my 61 Corvair Monza into a garage! It's been outside with a cover until our new garage was done. Now I can start fixing all of the little stuff.

Since I bought it, and even before, the oil/Temp light comes on and stays on when running. Today, I noticed that when I started it, when revving it seems to get brighter. At idle it gets dimmer. It stays on no matter what. I've heard that it could be a bad oil pressure sensor, head Temp sensor, OR possibly a ground wire. Does the light getting brighter point towards anything in particular?

Also, I am a complete newbie when it comes.es to Corvairs. This is a 61. Stock. Where would the sensors be that I need to check? Explain it like I'm five! Lol. These rear cooled engines are new to me so I have no idea where to start looking.

Thank you for the help!

That just shows your battery is low.. and your GENERATOR? is working... typical..

Vairs are not really different than any other 60's GM car..... just layout of parts is re-arranged..


1st pull the wire off the switch.... if light stays on... reach in the right T-stat Door and unplug the HeadTemp switch.

If light stays on you have a bare spot on the wiring that is "Shorting to ground" start wiggling the harness..

That makes since about the battery being low. Charger said it had 50%after being plugged in all morning. Its on a trickle charger now and will be overnight and the future.

As for the switch, that's the thing. Where do I look for it/them? Sorry if it sounds dumb... I just don't know where to begin. First older car like this, and have never seen or had a rear engine car before.

The oil pressure switch is next to the oil fill.

First off you need to make sure that someone didn't switch the bulbs in the Temp/Press and the Gen/Fan holes. I find it very strange that you can run the engine for any time with no oil pressure!

What you do is unplug the oil pressure switch by the generator pulley then just turn the key on, which light is on in the dash? It had better be the Gen/Fan light. If not then the bulbs have been switched. If both are still on there is a connector just to the rear of the coil, unplug that and turn the key on. If just the oil light is still on see below.

If the bulbs were switched start another thread with the correct problems.

I think some 1961s had the oil switch on the right side of the engine block. Most are next to the
generator.

I don't know if this will help, but here is a picture with the generator/alternator removed with an arrow point to the Oil Pressure Switch!

Thanks Matt!

Didn't buy one until 1962, so I am not familiar with the early design.

Agree with Dale. I thought that the oil pressure switch on the side of the block was a 1960 only feature. Thanks Matt.

I didn't know what year you had, 60 and early 61's had the oil pressure sender on the side of the block, so follow the wire from the pressure sender through the sheet metal and I still think the connector will be by the coil. Unplug that when you check the lights out.

Look in 61 shop manual pg 6A-51 fig 6A-101 to see position of
sender on the side of pass side case half.

Looked in the right door and saw a plug and sensor vertically in a cylinder head (head Temp I'd guess) and one a couple inches further in horizontally in the side of the block (oil). Unplugged the one going into the side of the block, hopped in, turned the key to on and started it. No light any more! smiling smiley

I also noticed with the key in on position the light does not come on like the Gen light. Is that normal? I'm guessing it is supposed to but since it isn't connected it's not coming on? Or maybe it's not supposed to...

If this sounds like it's the oil sensor/sender (sounds like it to me), does anyone have reccomedations? I've heard some new replacements are not the correct type.

Also, if it is the sender, how do I access it better to remove it? What needs to be done? There's all the sheet metal preventing me from getting to it. Does oil need to be drained, or does the level not reach that of the sender?

Thanks for the help everyone!

With the engine off only a couple of drops of oil will come out if you remove the oil pressure sensor.
