Bongo Fury

Any body used this type of gauge
even has a warning light if limit exceeded (100 C not changeable)

how to fit sensor

Sensor Mounting Thread: NPT 1/ 8 "
just wasted god knows how much time for stuff ive read before
some people are just organised or have memorys

by the way recently readjusted mod to existing gauge to 110 ohm gives a more sensible reading
will it stiill frighten me up hills

Were do I start?
The big issue with a good gauge is the speed of change, some are so slow the engine will be cooked by the time it shows up on the gauge bit like the standard Bongo one.
I have tried some other type of cheap gauge and they failed so I fitted one of haydns
If you use this one how or what will you connect the sensor to?

You have got the problem of where to mount the sensor. Drilling and tapping a hole in head is a risky job. Fitting new sensor in current hole (even if the threads are the same) will make the existing gauge redundant. Its better to supplement existing temperature gauge than rip it out altogether.

My personal choice is a TM2 with sensor attached to a rubber coolant pipe. I've also got a TM4 with a sensor on each head (V6 petrol).

thats why I ask the question
a while back there was a 40+ thread on where to put sensors and cheap gauges.
There is more than one, 2 ways to skin a cat! A laser or a Gillette is not the only way.
There may be more upto date advice

like forget temperature! measure pressure in the system or the concequences there of.


Are there additional positions to mount a sensor on head with or without an additional part/ fabrication.
Can get it made if dwg or sensible description available.

The problem with some advice is it may not be tried and tested.
We have an instrumentation depertment at work, they specialase in measurement equipment and controls temp, pressure etc.
I looked at making a sensor and gauge for my Bongo but to get it accurate and fast reading its cheaper to buy one off the shelf.
The chinese ones often look the same but the manufacturers make them all to different budgets depending on what you pay.
I feel the only way to get a good indication of whats going on is temp, pressure will give you some information but you need temp first.
You are looking for a change from the normal in the cylinder head, so the first issue is how to fasten the sensor to the head, you could bolt it on to the side of the head but that sensor may only be designed to read the temp accuratly through the very end. With the Ebay one it will start to raise more questions
How can I mount the sensor?
Can i read an accurate temp through the side of it or just the tip?
How accurate is it?
How fast is it?
How reliable is it?
One I tried if the cable broke it read 85 so the cable snaps it reads 85 and you think the engines fine? The proper ones show sensor fault if the cable brakes.
I feel the best way is to bite the bulet and buy a proper one I fitted this

To connect that gauge the op has shown above
You can buy a tee piece ( ally tube with a 1/8" female tapping
And you would cut a water hose and insert the tee piece
Then jubilee clip it up
Only about £10
But is it a weak spot you have created connecting the tee in?

Hi
I'm sorry to say that if you buy cheap, you buy twice...in fact more than twice....A decent gauge costs very many times more than 15 quid, but you MIGHT get a moderately good one for round about 40 -50 quid
What do you want to measure?....if it's water temperature, then you measure the temperature of the water.
Best place for a gauge is in the pipe exiting the head. You can buy something to put in the hose which has tappings for a gauge...these will have raised lips essential for fitting into rubber pipes.
Your cooling system will need bleeding, so take advantage of this and renew your hoses. In a V6 you might want 2 sensors, so have a switch-over to read sensors
Your Bongo is old, therefore it WILL need new hoses, and radiator, plus a water pump and thermostat. These are essential , before fitting any fripperies like conversions and wheels, or you may end up with a good looking Bongo that sits in your garage . You might think of changing the crabbiest ones first , and do them in blocks of 4 or 6 at a time.
Which gauge?...You have read that large numbers of owners have Haydn's gauges , and you don't read of them failing, so you have an answer...and just get a sensor that will fit into the tapped sensor....I expect he still sells them (or his daughter, now)
