Oil Temp Gauge

[wspeights]

I would like to be able to monitor my oil temp on my 1641SP.and I have seen senders and gauges in various catalogs. Where exactly are these senders installed on the engine? They kinda look like oil pressure senders. Help. thanks.

Hi Don,
They replace the stock oil psi sender on the side of the block. VDO has two types of senders: one for the guage only(one electrical post) and the other one has two posts, one for the idiot light and the other post for the guage. They are easy to hook up nad a worth while guage to have.

KAFER-CUP,
I have seen these dual purpose oil pressure Gauge/idiot light senders. BUT, I am talking about OIL TEMP. Is there a sender that will sense TEMP and Pressure?

DUH, brain fade got confused (again) sorry. The temp. guage I have is the drain bolt sender which obviously replaces the stock drain bolt. I have used the dip stick type but did not like them, both of them broke. Again very easy hook-up. I guess I should wear my glasses when I'm on the computer.

I have the oil temp sender that screws into the oil pressure relief at the bottom (not the drain plug), it gives the most accurate mesurement. you can get them from alot of different places.

Does it provide oil pressure relief also?

The VDO senders that take the place of the stock pressure relief plug don't impair the operation of the plunger in any way, and they're tucked up out of the way a little better than sticking out of the drainplate - but I wouldn't go so far as to say that they give a more accurate reading of oil temperature, there's really no flow past them so what they're really reading is block temperature (about the same thing but slower response to changes).

this is what I figured out....

I posted it in the speed and drag racing forum

So where is the optimal place to read oil temperature? Sump? In-line before cooler? In-line after cooler?

All good, and opinions/experiences will vary. Reading it in-line seems like it would give the quickest response if something were to go wrong, but most of the time just being able to compare steady-state temps from day to day is all you really need.

i run my temp sender out of a "T" adapter that comes out of the oil pressure slot. with the "T" there i can screw in the pressure/ idiot light along with the temp sender and i think this is the optimal place since this is going to be the coolest oil exept for the drain plug one but i have found that it gets in the way for me and the wire can get burnt with running it all around the engine. just my experience.

The *most* important thing is to have a good baseline to compare to - this means you can put the sender pretty much anywhere. The accuracy of the guages/senders has been debated, so dont worry too much if the actual reading is not "exact". What you want to know is not how accurate the temp is, but if something is wrong. Once you establish a baseline for the "normal" temp, then you will know you have a problem when it isnt reading at your normal temp. That said, I run my sender in a reducer fitting in place of the plug on the inlet side of the oil-pump. There is a LOT of flow past this area which makes it a great spot (pics somewhere on this page: http://bugman.50megs.com/FilterTech.html ).
