Single Temperature Sensor Kit


ENGINE GUARD EG01/1

Single Temperature Sensor System – easy D.I.Y with full instructions and free technical support

The ENGINE GUARD single temperature sensor system is an advanced digital temperature gauge with a user-adjustable audible alarm. Designed to warn you of overheating, the system will also provide very accurate real time monitoring of changes in temperature. Many owners report that they are surprised to see significant variations in engine temperature- whereas the factory temperature gauge hardly moves. This is because most factory temperature gauges only show LARGE temperature changes- typically in three stages being ‘COLD – OK – OVERHEATING’. But actual engine temperatures can change between 90°c and 110°c and the needle may not move! This is designed to give you ‘peace of mind’. Unfortunately, it can also go from “OK” to “OVERHEATING” in seconds- causing expensive engine damage. ENGINE GUARD will warn you before the damage is done!

With ENGINE GUARD you can monitor small changes in temperature- and take action. And the changes are detected very, very quickly. For example, on most vehicles an ENGINE GUARD will react to starting from cold in under 40 seconds. By contrast, most factory gauges take many minutes! And the ENGINE GUARD is remarkably good at detecting temperature changes due to load. As an example, we recently completed a test: a Toyota Prado was used to see the impact of tyre pressures on engine temperature. The test revealed that at 100kmh and 30psi tyre pressure the display showed 116°c but at the same speed and 40psi the temperature drops to 112°c. So you can adjust your driving style using the accurate feedback- (for example, change to a lower gear or slow down) if you see a gradual rise in temperature- particularly if towing.

Importantly the system uses a temperature sensor located directly on the metal of the engine– usually located on the cylinder head, on or near the thermostat housing. The sensor is installed like a washer under a bolt- quick and easy! And cylinder head temperature is a very accurate predictor of overheating- after all, this is where the combustion takes place. In testing, we have reliably demonstrated that if an engine has a sudden loss of coolant, head temperature will start to rise within 20 seconds. As the alarm set point is usually set around 2 – 5 degrees above the normal highest operating temperature, it will give a very accurate and timely warning. Equally, unlike traditional ‘immersed in coolant’ type temperature senders (as per most manufacturers) if you suffer a sudden catastrophic coolant loss, the ENGINE GUARD will still function perfectly. By contrast most factory gauges will DROP in temperature if there is no coolant- effectively telling you the wrong thing! The ENGINE GUARD will also show accurate temperature if the coolant is not circulating (such as a stuck thermostat or failed water pump) whereas immersed senders would fail to show any change.

The digital Display is designed to be simple to install and easy to operate. The Display mounts almost ‘flush’ on the dashboard (only 19mm thick) and can be located anywhere that suits the driver or operator. It also uses a high bond self-adhesive backing so no need to drill or cut into the dash. Operating the Display is simple- the system records the highest temperature in the memory making setting a breeze, and this alarm set point is displayed on start-up. It also features multiple error warnings if faults exist. There are also 11 adjustable parameters to allow you to customize the system to suit your exact purposes- from display brightness to alarm delay and reset times.

So don’t delay- ENGINE GUARD today!

Dual Temperature Sensor Kit


ENGINE GUARD EG01/2

Dual Temperature Sensor System

This system gives you the ability to monitor 2 different locations at the same time. For example, you could monitor:

  • engine cylinder head & oil temperature. This is easy- just slide a large stainless hose clamp over the oil filter, slide the sensor under the edge and tighten! No need to tap into oil galleries, etc.
  • engine and auto transmission
  • both cylinder heads on a V8, flat 4 or 6.
  • coolant temperature in and out of radiator on modified vehicles to test if the radiator is satisfactory
  • dual engine set ups such as boats or planes (yes, we have systems being used on planes..)

The Display shows temperature on sensor 1 as the default, but the operator can change between 1 and 2 at any time. In addition, if either sensor reaches the alarm set point and the alarm is triggered, the Display shows WHICH sensor and also the actual reading at the time. In addition, on start-up the Display shows both set-points individually.

This model is excellent value- giving effectively twice the monitoring for not much more!

Includes 1 x Display Unit, 2 x Sensors, wiring loom, plugs and full installation instructions. The system is supplied in a transparent retail package with hanger hole at the top.

Single Temperature Sensor (input 1) and Voltage Meter OR Low Oil Pressure Alarm (input 2)


ENGINE GUARD EG01/3

Single Temperature Sensor (input 1) and Voltage Meter OR Low Oil Pressure Alarm (input 2)

Digital engine temperature alarm with single bolt-on sensor (INPUT 1) with user programmable second input (INPUT 2), either:

Digital volt meter with optional high or low voltage alarm.

Measures voltage in a range between 0v DC – 33v DC. The alarm set-point is user programmable for high or low voltage alarms. Great for dual battery set-ups (warns of overcharging or discharging that can cause damage to batteries), alternator monitoring, starting battery condition, etc. Simple to install- a single wire (supplied) can be connected to a voltage source using the same earth/negative as the Display. The voltage is then displayed on the digital display as INPUT 2.

Low oil pressure alarm

– connects to the standard oil pressure switch circuit (most vehicles use a single wire/normally closed system) and will trigger the buzzer when the low oil pressure warning light is illuminated.

This model is very versatile- ideal for fleet owners who may have contract drivers who are not familiar with the factory warning lights, etc.

Bolt-on Temperature Sensor (only)


ENGINE GUARD EG01/SEN

Bolt-on Temperature Sensor (only)

Features a simple-to-install 10mm diameter bolt-on sensor. The highly accurate imbedded thermistor provides virtually instant temperature readings. The sensor is versatile- it can be bolted to a location on the engine, transmission, differential, etc. and will display temperature changes due to ambient temperature, load, etc.
