Do you honestly think that Thornycroftengines would sell or fit inferior parts when they are dealing with such Expensive Engines.

Sorry Rita, I only looked at the price, which struck me as cheap for a complete bit of kit. And my (ebay) experience has been that cheap stuff let's you down. Are you saying this is industrial quality stuff at a bargain price, backed up by a major engineering company? My sincere and grovelling apologies if so. Where are they manufacturing it, and what is the quality control regime?
Yes I remember the name of your company from years back (Vosper Thorneycroft specifically). It would never have occured to me that they would end up selling direct to consumers on ebay. How times change! They need to turn that 99.7% rating into 100%
Any thoughts on the other points in my post?

Thornycroft Engines also sell kids plastic sledges.....

...and pond pumps:

Other than a name in common, I don't believe they are connected to VT Group (formerly known as Vosper Thornycroft). According to Companies House, they are registered as:

I have a TM2 on my V6 fixed in the same place. The readings I get are very much in line with Jim's. Cruising between 72 and 78 degrees, with upward readings in the eighties for traffic. In a real crawl on a boiling day I have reached 91, but then the scavenger fans get going and it drops. It may not be perfect but it provides a good indication of what is going on and how the cooling system is performing. One of my best investments on the Bongo.

Hi
Vospers stick in my mind, as they produced some pretty good MTBs in the war...merged with Thorneycroft in the '60s, selling on e-bay in the 21st century.....there's a bit of a parallel with the British Empire there somewhere
Cheers

Thanks for all the input guys, I think my Tm2 is giving me substantially more protection than my standard temperature gauge. It's not perfect, however I think I will have a punt on Rita's gauge an give it a try. At the end of the day 2 gauges sampling temperatures from different areas of the engine should give me more piece of mind. New Terriers, readings (72'c-80'c) are similar to the range of temperatures I am receiving, and the 40mile test drive over the weekend, plus your posts have reassured me that my cooling system is working ok.

Just to state a point...
This Is Not MY Gauge..or
or My company (wish it was)
I merely... stated ....Quote ....
You would probably be better with one of these rather than the original gauge.
If anyone thinks different that is Their prerogative.
There seems to be a lot of FURY about when someone mentions something fairly new.
Its nice to be important,but its important to be nice.

Sorry Rita. I honestly wasn't trying to be sniffy about something new. My concern was over replacing the original sensor with a cheap component. But if its only the gauge, i'm less concerned, as you can generally see if that has failed. Then again, there's nothing wrong with the original gauge except it is heavily damped so doesn't show any but the extremes of temp variation. But remove the damping (with a Masons alarm or similar) and things get better. Not as eye catching as the TCE gauge mind you, and it doesn't show the numbers.

Hi
Rita...not being sniffy about the gauge, in fact any old thing is better than the Mazda gauge for the European market....the best place in my mind is to cut the top hose and put an adapter in when doing a coolant change, so you're reading the sum temperature of the head output....To be fair, the Mazda gauge is fine, but it's the nut behind the wheel that's the problem....IF we see the gauge rising, we should pull over and get the problem sorted which is, I guess, the Japanese mentality....in the jolly old UK, the attitude is to drive home and see what's wrong tomorrow....enter the cooked head scenario!
My personal preference is for the odd gauge or two...

...and a Mason type alarm allows the standard Mazda gauge to move in proportion to temp changes, and ultimately you don't have to watch it 'cos an alarm will go off at whatever threshold you've set it to anyway. Having said that, I don't have a Mason fitted, and my TM2 remains in its box, waiting to be fitted

I know

and the only excuse I can offer is everything suggests I have a Bongo with a healthy coolant circulation

But really, these old buses are worth keeping a close eye on, as a rule. I'll get a round tuit one day

Sorry Rita when I mentioned "Rita's Gauge" I knew what I meant, Just to clarify to everyone else, I am going to fit one of the gauges that Rita suggested I look at on ebay to replace the dashboard standard gauge in the bongo (which is useless.) I will feedback how well it performed once fitted and tested for a few months.
