ENGINE GUARD Overheating alarms – get warned BEFORE damage occurs

Engines overheat and fixing the damage can cost serious money.  In most cases no warranty or insurance applies.  You pay the repair bill & do without your car until it’s fixed.

That’s why you need an ENGINE GUARD.

  • LOUD audible warning – keep your eyes on the road & drive more safely.
  • Get warned BEFORE damage occurs- super fast response compared to factory gauges.
  • Works if you’ve LOST coolant- shows cylinder head temp. Most factory gauges don’t work without coolant.
  • Digital display in degrees- provides feedback to MANAGE engine temperature.

About Engine Guard

The Engine Guard uses a completely separate sensor and an accurate digital display- totally independent of the factory temperature gauge.  This will enable you to see changes in real time- quickly and accurately and avoid engine overheating.  YOU set the audible alarm to warn you if the temperature is higher than normal.

Other models: the ENGINE GUARD can do more.  It can also monitor the temperature of your transmission at the same time- great to know if you’re towing a caravan.  Transmissions have dramatically shortened lifespan if overheated and can also go into ‘limp home’ mode without any warning- guaranteed to ruin your travels! ENGINE GUARD can also be used to monitor engine oil temperature- a great feature on turbo diesel engines.

It can also be used as an AUDIBLE low oil pressure warning, or to monitor voltage with an alarm to warn of low or high voltage.  This is ideal for vehicles with dual battery set-ups.

Customer Testimonials

This might sound like the commercials, in all honesty, this post is absolute truth.
After an overheat and limp mode etc after pressure from a crack in the head was over pressuring my cooling system and popped the plastic top off the radiator as well as constantly spitting out fluid, I took my 4WD to my mechanic to actually find that crack in the head. Whilst the head was off the block my mechanic noticed excessive bore wear in piston 1 and 4. Usually from towing caravans. So we proceeded with full engine rebuild.
After I got the vehicle back I immediately installed an Engine Guard to give me that sense of security rather than relying on the stock dash gauge.
So, after 4 years and only around 40K Klms, I started to notice my 4WD running slightly hotter than it had previously. Not much of a change, maybe 4 to7 degrees Celsius. The dash gauge remained at normal operating temperature mark. Towing my trailer resulted in a 10 degrees Celsius difference. The digital display works wicked in noticing slight changes. So, back to mechanic.
We found that the clutch on the engine fan had failed, unfortunately (then again maybe a bonus) my vehicles fan and water pump are one unit.
Without Engine Guard I would not have noticed those slight elevations in temperature and possibly ended up with a bigger mechanic bill than what I had.

I just installed Engine Guard to my 38foot Baycruiser on a 120hp Fiat diesel. Have to say it’s a remarkable unit. It took less than an hour all up from start to commissioning.

On long trips I often found myself unaware of just how hot my engine was getting. I was too busy watching the road.
Since getting EngineGuard I now know the exact temperature she’s running at, for about a hundred, bargain.
You’re mad to travel without one.
