Do you honestly think that Thornycroftengines would sell or fit inferior parts when they are dealing with such Expensive Engines.mikeonb4c wrote:I wouldn't do that. My concern with cheap goods on ebay would be reliability. Will their sender give the reliable operation over many years as the Mazda item. In reality, a mason modified temp gauge is doing the same job only without the numbers. Not as attractive a piece of eye candy as the ebay item I agree but...Jim the Box wrote:Spot on Rita I was thinking the very same myself, will try some sort of shroud/heatshield, failing that will look at the fitted temperature sensor location to see what options I have. However, I think the TM2 would alarm out if I was having a boil up for real. I'm just so relieved that everything seems fine. If I do replace with the new gauge (shown in the thread above) I assume that the 1/8 sender they supply would fit directly into the existing temp sensor location or would I need an adaptor?
And surely a tm2 does at least attempt to measure a local (head) temp, whereas the coolant system actively tries to keep temps within a working band and so arguably extra effort by cooling fans could mask a developing problem? The problem for the tm2 is to achieve standard fitting position on lots of Bongos so data on what is normal can be gathered.
