Have two in my 6.0 LS powered boat . You cant read gauges all the time . Its very important to fit in correct place on heads etc that WILL get hot if coolant or pump etc fails .

We have an engine guard on the Coaster. Measures oil and engine temp - alarms if there are problems. Some years ago, mechanic didn't tighten lower radiator hose on Hilux we had then and we cooked the diesel engine. The temp gauge on dash did not deviate from normal - that was how we found out that they rely on there actually being coolant in the radiator! Similarly, best friend lost coolant from Troopy, driving. No temp gauge warning. Had to get new engine! So some sort of more direct system is well worth the effort and cost of having.

I hooked up a dash light for my thematic fan. Light goes on I keep an eye on the temperature. Easy

Bilbo, i also use an engine guard unit, light on dash only tells you when motor is cooked. Is about $100.00, can self fit but make sure is attached to head (not engine cooling fliud) or block, Regards

Bilbo,
I put one on my last Nissan mainly because the bottom of the radiator & bottom hose hung low.
Cost about $110 - a chap in Ingham made them. Audible + visual alarm. Went off with a cup full of coolant lost.

Compare that with the $6,000 that a friend (who has no mechanical knowledge) had to pay to get his car rebuilt after running low on coolant & cracking the head of his Navara + cancellation of their trip. Said the Tanami road was too rough for him to notice the temperature gauge!!!
