Bongo Fury

Hi All. can anyone tell me the average running temperature of the engine in centigrade . thanks steve

I have a digital thermometer connected to the cylinder head on my 2.5 TD.

According to this device the average running temperature is around 92/93 degrees centigrade.

It seems to run hotter on rape seed oil though. Only a little.

When switched off the temp can go to 105 degrees centigrade or so. This quickly goes down when the engine is running. Good indicator of the cooling fans and general condition of cooling system.

Summer months it runs somewhat hotter.

Must admit that I look at this digital read out more than the speedo.....

Also has the ability to have a siren running at custom temps. Works a treat for me.

Love it.

Hi. thanks for the info . sound just like the one i fitted today this also tell you alternator voltage. seems to run at the same temperature as yours. temperature sensor tapped into the cylinder head. thanks steve. £9.99 inc postage.what a deal.

That looks like a nice little unit - have you got a link for the place you got it from?

Hi steamysteve .ive pcd you if you could read it and maybe get in touch ,cheers

Hi Simon,if you cant get these units locally you can get loads of them for buttons (bulk buy 10 units or more)from made-in-china.com

Hi. unit is from e-bay item no 261005113554 now £10 .49 . i think if you bulk buy to resell as sugested you will get custons and exise charges. for the price this is a good quality unit . only one downfall is that the alarm setting for temperature is set at 98 deg c. . also has alarm for low voltage. i disabled the buzzer so i could just see the running temperature. and voltagr without the buzzer. if you are a electronic boffin you may be able to fit a pot to reset the temperature setting. but not me

As yours got a dedicated temperature sensor that is in direct contact with the coolant like this one ..??

Thanks for that info bn on and just ordered one up .take it easy enough to install?did you experianced any probs/what route were the wires put?

Hi All . this unit has a 1/8" bsp (british standard pipe) thread. there are two options.
1 /like i did . above the oil filler there are two 8 mm tapped holes . approx 25 mm deep the same as the sensor probe, if you drill this hole out to the depth of the probe 7.3 mm dim ,and then drill out to 10.3 mm to depth of 12.5 mm and tap 1/8 " bsp. screw in sensor with dialectric ht grease to help make contact.
2/ make alloy boss with 1/8" bsp female thread with 8.5 mm hole at 90 deg for bolting to cylinder head..

will take picture tomorrow for clarity. if anyone want's the second option i can make for you for the cost of postage as i have all the equipment to make. regards to all.

I willingly will pay for the boss to be opted for let me know and I canpm you details and arrange payment etc
Thanks gordon

Another possible source is McGill motorsport (http://www.mcgillmotorsports.co.uk/)
A nice range of plasma gauges that might match very nicely with plasma dials if you have them. They're 50mm so might fit into a BMW clock cubby?
Also, Koso do a nice petite digital gauge and sender. It's around £40 from eBay or other online vendors, but blue display and very neat (around 50mm x 25mm), fitting mine tomorrow with an inline sender in the top hose.

My first post on BongoFury, thanks for all the great info so far, invaluable for a new owner

this is my gauge, somewhat more expensive though.

Mine has the TM2 sensor back of cyl head. 87 to 89 in town and A Roads 87 to 94 on motorways depending on gradient and weight of right boot. Higher on huge moutains in Yirrup up to 101 IIRR.

With regards to town and motorway, your sensor reads the opposite to mine. Mine is in the coolant leaving the head.
Stop start driving heats the Bongo up faster than motorway driving it also locks the gearbox up sooner. It only takes me a minute or so to get to the M6 from home so comparison is valid at startup.
In reality we are only reading numbers, so if they stay the same we know all is well, but as I have said before, reading the coolant temp leaving the head allows you to be proactive rather than reactive.

McGill Motorsport are exellent to deal with and supply CNC alloy connectors to take sensors at a price I couldn’t buy the billet to machine.
