Bongo Fury

I can understand why people think about running the fans, prevention being better than cure. Previously when the head on ours failed, all the fans cut in but obviously that situation was far too serious for the fans to help.
Since fixing it, we've found that our engine operates fine without having to engage the fans ourself. Around town and when thrashed uphill the temp reads 80 and on a run it's 70, we're happy with that.

big daddy cain - I percieved breaking the circuit as expained in my last post,

I would never medal with an ecu, putting voltages on as dandy thought is bad news,

Also the senario with towing is one I comprehend as I will be towing a bit of weight - I have used this mod on a motor cycle used for stunts, where it revs high with very little air movement through the rad, and I believe they do something similar with hill climb cars some times.

Prevention is better than repair,

but obviously there is no point cooling uneccessary, I dont know the exact consequenses but running an engine to cool is bad too -

I think in the cases I'm used too it is because oil pressure is higher with thicker oil which can damage a screaming engine and it can reduce horse power - not relevant with a bongo - I know on some machines not getting the engines hot can cause oil to emulsify too with out burning any condesation off that can form in a sump - as well as other things no doubt.

deg c gauge, coolant alarm, silicone hoses, and a manual open ciruit fan switch seems the way to go! " jobs a good one.

(think I might look into making my own coolant alarm £130ish? seeems a bit dear for some components, although I know that involves a trick box etc. I just want an led and buzzzer with a sticker to say COOLANT.) -Yes 130 is cheaper than a head rebuild. I have seen electrodes etc.. used to sense moisture, I'm sure maplins and the like do some sort of kit.

Basic coolant alarm is roughly half that Karlos.
