Location of the oil temperature sensor?

Hi all,

Can anyone tell me where the oil temp sender is on the 1750 twin carb?

I'd been told it was near the oil filter but I can't find it. There is something that looks like a sender on the back of the engine block. Is this it on a 1750?

Please excuse the poor picture. Any help is appreciated!

Hi:
As far as I know, 1750's did not have temp senders. The sender at the back of the block on the right side is the pressure sender. There was also a sender at the oil filter housing on the left side and that was for the idiot light.
Regards Ian.

Sender is electric, socket under back of inlet manifold. Half a tick though why are you asking this question on the Giulietta thread with a 1750? Or have I misunderstood things once again.

I'm asking on here because it's a 1750 in a Giulietta Spider.

Cheers for the info!

What you appear to be showing is the vacuum takeoff for the brake booster. Some 1750s had oil temp; it's on a sender on the top of the oil filter base, right? Isn't that where the oil light sender is too? The sender for oil pressure gauge on 1600-2000 is at the RR of the block, just below the rear of the intake manifold, above the starter.

Tom
The 1300 engine originally fitted in the Giulietta had an oil temp sending unit threaded into the rear end of the oil pan. Its purpose was more to indicate that the oil and engine had reached designed operating temperature rather than for overheating prevention. The oil temp indicator needle rarely moved any significant amount; that is on the rare occasion when it was working.

If one insisted, a 1750 oil pan could be threaded to accept a temp sender but why not keep the tri-gauge looking "as original"? Simply leave the oil temp sender wire ... unconnected!

The step nose GT Sprints and Jrs. also had a oil temp gauge. The sender was mounted on top of the oil filter base, as Andrew recalled, however it was only on 105 1300 & 1600s - not 1750s as far as I know. You could fit one of these canister housings to your 1750 quite easily if you found one. The part # for the oil temp sender is the same as the water temp sender on that engine (just measuring liquid temp, right?). Now, whether that sender has the correct resistance for your Giulietta gauge or whether you'll have frame rail clearance issues with the oil filter cannister, I can't tell you.

Dang, faulty recollection again. Correct that no 1750s or 2000s that I've ever seen have had oil temp; just oil pressure and oil pressure light.

Thanks for your help on this.

I'm starting to come around to the "keeping it original" idea and leaving it unhooked!
