I have a load of gauges 2 of them being a mechanical oil temp and an electrical oil temp which is better and easier to fit to my series 2???? also is a oil pressure mechanical gauge any good??? thanks in advance......

 

Electrical is always easier to fit as you dont have to run any pipes!

Oil Temp, i would go with electrical because by the time the small amount of oil coming down the pipe gets to the gauge it will probably have cooled quite a bit and give you a false reading (TBH i didnt know you could get a mechanical oil temp gauge?!).
Oil Pressure, mechanical is better it has a much faster response time!

 

thanks for the quick reply, yes i have a mech oil temp and an electric one, thats good as i know now which ones to keep and which to put on here and fleabay!!!!! also is volts or amps better??? and is it good to have a electrical water temp gauge??? cheeRS

 

You already have an electrical water temp gauge........... next to the fuel gauge!

Volts is useful to know if you worry about your alternator charging, Amps will tell you howmuch power your car is drawing (depending where you wire it in), personally if it was me i'd use the voltmeter not the ammeter.

 

yes i know m8, but the ford gauge water and petrol are very tempremental as we all know lol, so would it be a good idea to have a seperate one or should i not bother?????? cheers

 

It's up to you mate, always good to know your water temps!

 

where abouts does the oil temp and pressure gauges hook up too? The instructions with the gauges say to replace the sender units to the warning bulbs but am not too sure.

 

oil temp has a sender that goes into the sump i think, and oil pressure has an adaptor from the back of the oil pressure switch, but am unsure like you mate!!!

 

lovely thank you, what about water temp? Anyone shed any more light on the oil pressure hook up?

 

again dnt quote me on it.. ive put them in my fiesta rs2000 an put the oil TEMP sender in the sump plug (u can buy the plug with a threaded hole for the sender) an the oil PRESSURE i had came with a sender for it that goes in place of the ford item an u connect to that. mine seem fine an never had any probs an the water i replaced the temp sender for the 1 supplied with the gauges again never had a problem.. the water may be different on rs turbo tho but oil temp an pressure should be roughly the same!

hope its of sum use!

 

ill have a look around tomorrow and see if i can install it.. got a mission of a job installing my toad alarm... not simple at all, well not too bad just a big job!

 

Pure rubbish,you can get a mechanical oil temp guage in any good raceparts shop.And it does'nt feed the oil up to the back of the guage to read the temperture!!!!You place the sender in the sump,the sender is filled with mercury.As the oil heats up the mercury expands,thus increasing in volume,this then moves the mechcanisim in the back of the guage,moving the needle.Regards,Micky

 

Use a sandwich plate to hook up your Oil gauges, and get an adapter to fit in between your top rad hose for the water temp.

Heres the sandwich adapter:

thanks alot Karlos, yet again you help me out! Top man

 

thanks karlos for your help,

 

Sorry Micky, like i said i didnt know you could get mechanical oil temp gauges hence i also didnt know how they worked, was just a guess mate!

But placing the sender in the sump will not be the best place as the oil will be a lot cooler there than if you use the sandwich plate adapter linked in my previous post and take the reading as it's coming out the block!

 

Wrong again Karlos!!!!!!Where does the oil pump pick up the oil in the engine??????

Answer........In the sump.

So thats where you need to know the temp of the oil.As this oil is then STARTING its journey around the engine.Look at any wet sumped race/rally car,the temp sender is always in the sump.That sandwich plate is only for people who dont want to job proper,ie remove sump/drill and tap hole,fit sender and then refit sump.Best regards,Micky

 

If I am not confused the mercury has been forbidden a year or two ago, like the asbestos case in the 90´s.

At least, it´s totally forbidden buy or sell mercury thermometers in the EU, I do not know if it affects other gauges as well.

 

I have no expereince with race/rally cars, but when this has come up on here before everyone seems to say that the sump is the wrong place to fit it, i know that everyone is not always right (myself included) but to me it makes sense.

Surely it's the operating temp that you want to know (ie: as it comes out the block), because you base your oil choice on how hot it will run, if you are going by the sump temp then you could choose a oil with a much lower temp rating than what it's actually getting up to as it goes through the engine and will be to thin giving you low oil pressure.

For me at least, i want to know the MAXIMUM temp my oil is at, not a cooler sump temp.
This is just my opinion of course!

 

Milesy23rst, Have you sorted it all as yet?

 

This post is 4 years old m8 lol and yes sorted ages ago m8
