temperature sensor - TVR 1600M

[urraco62]

Hello
I have a TVR 1600m (1973)
What is the correct temperature sensor for my 711M crossflow?

I tried sensors of different colours (white from Cortina 1600, black or purple...)and each time the needle gauge (SMITHS temperature gauge) climbs gradually and ends in the hot while the water temperature is normal (between 80 - 90° C)
What do I sensor mounted on my engine?

Thanks

The Temp gauge has a voltage stabilizer that controls the gauge (that and the fuel gauge) and this should be checked, it is an earth dissipated item and should be earthed. The stabilizer needs to match to the amount of smiths clock being used. It would appear that you already have a sender/stabilizer, but if you get stuck I carry them.

Yep - it's a very simple device - a bimetallic strip which oscillates on and off. The voltage output is around 10v when averaged. The gauges react so slowly, because they also rely on the old bimetallic strip, that you never see the switching. As Adrian quite correclty states the load on the regulator has a direct result on it's efficacy.

+ 1200S Coupe - that's a rare car in your fantasy garage?

Thanks

I will check this voltage stabilizer (and perhaps connect).

SIMCA 1200S: a small French GT which has Italian origins to the bodywork (Bertone) so that is bio-degradable..........

Try Fleabay item 130221399299 trust me these things are brilliant.
Fitted 5 off to different cars in past inc TVR 1600M.

[urraco62]

I changed the voltage stabilizer and the result is the same.

I measured 9.94 V output voltage stabilizer. The connection is in accordance with the instructions on assembling


Now what?

[Adrian@]

What type of connection has the sender got...bullet or lucar?

Try Merlin motorsport at Castle combe(tel [phone]), i had this problem and ran with it for years a chance chat with these guys and i now have the correct sensor. If the voltage stabliser goes wrong then you usually get fluctating readings on the fuel and temp guages. Dewi

[timelord]

Got to agree with Dewi here, spent ages and lots of cash trying to cure an "overheating" problem on my '72 1600M. The sender you have got is the standard Ford one and matches Ford clocks, the one Merlin supplied me with has a spade connection and matches the Smiths clocks in the M. Geoff

[urraco62]

thank you for this address

So that is this sender:
Product: SMITHS TEMP SENDER 1/8NPT
Model: CB-TS-18
Brand: CAERBONT
Categories: SMITHS CLASSIC SENDERS - INSTRUMENTS


I wondered if this sender can be mounted with the old or new temperature gauges and without problem. That reassures me about this purchase, me too, I'm tired of spending money wrongly.

[thegamekeeper]

Sometimes its better to avoid trawling the net and frequenting chat rooms to try to save a few pence, or cents in your case. I keep these in stock, have done for 35 years and there is only 1 sender fits all standard 1600M's, they are not expensive, much cheaper than a blown head gasket.

Bruno, thanks for your reply off this discussion. I dont fully understand what you are saying although your English is better than my French. What you seem to be saying is its your hobby to find out alternative sources for parts so all I can do is wish you luck with your hobby sTeVeR

[Seabass]

mmm. Great attitudes on here sometimes...

Bruno,
did you find a sender that worked?
I'm now looking for one for my 1600M.

Hello

Yes, I found a sensor that works.

after trying sensor of ford cortina or escort, nothing worked properly.

A few years ago, I bought a set of used sensor (oil pressure, water temperature, gauges....) for rally cars.
I tested all of them: a pan of hot water, the gauge of TVR, an electric fuel level sender (rheostat), a thermometer and an ohmmeter.
Among the sensor, only one worked : UNF thread, a spade connector, a white insulation. But there is no marking on it.

So I don't know the origin of this sensor

I'm really sorry, I wanted to help you a little more

VixeM said:

Thanks Bruno,
white insulation colour would suggest is a Ford sender. Burton power XTT14, for BDA, Lotus Twink, Early pinto, some x/flow and pre x/flow?

Cheers
Stephen

I bought the same sensor, but it doesn't work with the gauge of the TVR 1600M.

Should have gone to Steve Reid (gamekeeper) or Adrian Venn (Adrian@)

i know this thread is old...but did you fix the problem?

i have the same problem over here: ford xflow engine in a kitcar and a smiths (voltage stabalized) instrument from a triumph dolomite.

the original triumph sender is very big and has a 5/8unf thread. the model is GTR108, also used in Rover, MG´s and certain other cars. can be sourced e.g. at http://www.rimmerbros.co.uk/Item--i-GTR108


finally i bought a thermostat housing from a fiesta, which has a M22x1.5thread for an otter switch. i also bought a thread adaptor from M22 to something and machined a 5/8unf thread in it.
as the new thermostat housing also had a differnt location of the water hose connection, i had to modify this, too.

finally a real complicated job for such a "stupid" thing like finding a matching sender to an instrument.

i still dont like this "unusual" solution as i would prefer the sender located in the original position (1/8"thread) and converting back to original thermostat housing and cooling hose.

so have you found a matching sender with 1/8" thread? if yes, how is it named and where can i buy it?

so finally no solution?
