Posted: Fri Feb 14, 2020 7:15 am Post subject: Quick question on Oil Pressure and Oil Temperature |
|
|
Gents-
Close to wrapping up the rebuild of my stock 1973 standard beetle 1600 dp engine. Oil pressure and Oil temperature are two things that I wonder about.
From what my understanding is, this year car was built with a basic Oil Pressure Sending Unit (Idiot Light Switch) screwed in the case, and wired to the back of the speedo.
I also understand this year model did not have oil temperature switches or gauges. I see people do use Single and Dual Pole sending units in lieu of the basic switch.
So I guess my question is really, should I use the basic switch and wire to back of speedo only? Or should I also consider adding a temperature sensor (and gauge)?
Thank you
-Mark |

No aircooled Beetle has a oil temp from the factory.
It's not a bad idea to add one but you need to verify that it's accurate... most are not. _________________ Glenn

Thanks for the replies. I've been reading about the dipstick. Mixed reviews. Seems like it has merit though.
It would certainly give me at least "some way" of checking and I really don't want to add a gauge, as my dash does not have one nor a spot and I'd would need to drill one in place or mount it externally which I really don't want to do. |

I have the dipstick from aircooled. It works, but it's hard to read the oil level on it because of its chrome so carry the stock one for that. Mine also has moisture under the glass, also makes it tricky to read the temp. _________________ Eventually, "we are what we pretend to be.’”

Vamram ... did you notch or scribe the Empty and Full lines on their dipstick? One of the videos I watched, the guy did that and said it reads it well. |

I have both a temp gauge and the Save-A-Bug dipstick.
I also keep the stock dipstick in the glove box. _________________ Glenn

Thanks Glenn. Good to know. That is what one of the gents did too, keeping the stock dip in the glove box. |

If it's just a daily driver with a stock motor there is no need for temp. gage. If you push it hard and run down the freeway at 70MPH most of the time then you need one. These cars have done fine without one for 50 years it stock and slightly modified condition, don't over think it. Clean oil and the correct oil level is the key. |

I have found the stock pressure location is a nice place for a temperature sender. The temperature there read nearly the same as that of the oil in the sump. The relief valve location is problematic do to the sender being exposed to road debris.
As for senders, Aircooled.net is one of the higher priced vendors. you can by buying elsewhere save a good deal..
...
$44.95 at aircooled.net, verses $32.46 (free shipping too)
http://vwparts.aircooled.net/VDO-80psi-Oil-Pressure-Sending-Unit-1-8-27-NPTF-p/v360003.htm $44.95
https://www.amazon.com/VDO-360003-Pressure-Sender/dp/B0000AZ616 $32.46 yippie!
If given one of the gages, temperature or pressure of oil, Id pick pressure as the first choice. the pressure will be influenced by temperature. so high temps will be seen as low pressure, plus oil starvation will be instantly indicated by a low pressure reading. A temp sensor wont give you much help in the case of oil starvation.

Right, and you got the part number off aircooled.net
VDO makes a variety of senders, there's a very good chance that if you buy the one aircooled.net recommends it'll work for the listed application.
There's some value in that (esp if I wanted to, say, link an example sender in a forum post), and most ACVW shops aren't going to be price competitive with Amazon.

Agreed, I just run oil pressure (plus voltage and a tach) as well.
If you watch it for a bit you learn the usual ranges and can then tell when something is wrong.
A SaveMyBug dipstick is great for a simple idiot light though.
I also just keep my stock dipstick handy. |

Both Amazon and higher priced Aircooled.net sell the same part number VDO product. That part number can be found on either website. However the part number is much more prominently displayed on the Amazon page. (It took some searching to find the VDO part number on Aircooled.net) The application is also listed on both websites, both list pressure range and thread size, however Aircooled.net does not list the voltage, while Amazon does, an important consideration if you drive a 6 volt Bug. Amazon list voltage range of 6 to 24 volts
I find it unlikely the sender sold by Amazon will be less likely to work than that sold by the higher priced Aircooled.net. One seller is a good deal less expensive than the other, and there is some value to that!
Also Amazon has free shipping, Aircooled .net to central California lists $10.40 as the cheapest shipping price
Thus $10.40 saved on shipping, $12.49 saved on price equals $22.89 Saved! That's a good savings.

Well, I did end up getting the standard oil pressure sensor and the dipstick. I figured an easy solution to keep an eye on temp. |

I personally run with the SaveMyBug dipstick. Overheat warning is great on 90F+ days running on the mountain highways here. That little flickering light has taught me lots about my engine's "tendencies" which has proven a great value for the $30 or so it costs.
Additionally, you can estimate the oil temp via a bit of calculations for the 'wire' of the SaveMyBug. Orient it such that the contact screw is at the "12 o'clock" position and you can gauge your oil temp at pit stops by visually looking at what "Hour" the wire is at.
Generally speaking, my bug runs between 9 and 11 o'clock on the the "clockface" of the dipstick- which equates to 180F-220F (all dependent on temperature, driving type, decklid prop or not).
If you choose to do this, you'll need to calculate your dipstick to account for any variation between units. _________________ 1973 Standard Beetle

Concerning aircooled.net prices, as opposed to Amazon, I’m not so destitute that I’ll save a few dollars by going with Amazon.
Good, honest VW vendors need our support. And, unless you pay a yearly Prime fee with Amazon, you don’t get free shipping on most items.
Regardless, my preference is to shop VW vendors, period. The more business that goes to Amazon, the fewer old and trusted VW vendors can stay in business.

$23 in savings is great salespersonship.
Plenty of great knowledge on Samba comes from non vendors, rather than coming from high priced vendors.
