Waterless Coolant

Evans Waterless Engine Coolant

Evans Waterless Engine Coolant

Evans Waterless Engine Coolant

We have recently converted one of our vehicles to Evans Waterless Engine Coolant, using Power Cool 180. Evans Waterless Coolant. Evan's Power Cool 180 High Performance Waterless Coolant for performance & track cars is designed for high performance engines fabricated from a mixture of cast iron, copper, steel and aluminium components. It has a number of advantages over conventional coolant, which are listed below.

Conversion to Waterless Coolant is fairly straightforward, with using Evans Prep Fluid is formulated to hygroscopically absorb water whilst flushing loose dirt and scale from the cooling system prior to filling with Evans Waterless Coolant. The job can be completed in just a few hours by either a professional workshop or competent enthusiast.

Benefits of Waterless Over Water-Based Coolants:

Eliminates Overheating
Evans Waterless Coolants have a boiling point above 180°C and will not vapourise, thus eliminating overheating, boil-over and after-boil.

Reduces Pressure
Evans Waterless Coolants generate very low vapour pressures reducing strain on engine cooling system components.

Prevents Corrosion
Evans Waterless Coolants contain no oxygen effectively eliminating corrosion.

Increases BHP
Evans Waterless Coolants eliminate pre-ignition and detonation caused by overheating, thus improving combustion efficiency and delivering more power.

Stops Erosion Evans Waterless Coolants prevent cavitation and eliminate liner and cooling pump erosion.

Freeze Protection Evans Waterless Coolants freeze below -40ºC.

Non-Toxic Evans Waterless Coolants are proven to be Non-Toxic. Standard anti-freeze is toxic and known to kill pets.

From what we have seen and heard about this product so far we are confident that it will outperform all expectations. Prices for Power Cool range from £29.95 - £64.95 and £15.99 - £39.95 for Prep Fluid. Available by Mail Order (Tel: 01692 404313) and online.

How it Works.....

Water is an excellent fluid for cooling whilst in a liquid state, but when water turns to steam it has virtually no capacity for heat transfer. Evans is a superior fluid for transferring heat in engines because it remains in a liquid state until above 180°C. This article details the benefits of a significantly higher boiling point.

Within an engine cooling system the hottest surfaces are those adjacent to the combustion chamber, specifically the cylinder liners and cylinder head. In these hot spots water is likely to vaporise preventing efficient cooling and causing loss of performance and unnecessary engine damage. When the coolant fails in this way the engine becomes even hotter causing more hot spots and more steam.

Evans waterless coolants will not boil around these engine hotspots maintaining efficient cooling performance even when the engine is put under extreme conditions. When water turns to steam it pressurises the cooling system putting strain on hoses and other components. The significantly higher boiling point of Evans coolants means 75% less pressure than water resulting in a less stressed cooling system.

Water contains oxygen which causes corrosion and also allows electrolytic activity which further damages engine metals (chemical limitations of water). Evans waterless coolants eliminate corrosion and electrolytic activity significantly increasing the life of the engine.

Nucleate Boiling
Nucleate Boiling

Traditional water based coolants regularly cross the thermal boundary that separates efficient Nucleate Boiling (A) from inefficient Critical Heat Flux (CHF). CHF is synonymous with the condition 'Departure from Nucleate Boiling' (DNB). When DNB occurs, a layer of steam bubbles form adjacent to the engine hot spots (B).

Steam dissipates less than 1/30th of the heat that water does, rapidly over-heating local metal, causing premature detonation. The high boiling point of Evans Waterless Coolants, such as Power Cool 180, prevents DNB providing more efficient cooling in engine hot spots.

Camber Bolts from Powerflex

19 Mar 2014, 11:36

Powerflex have announce a new ranged of PowerAlign products under the Powerflex umbrella.

The range of products will grow over the coming months. They will be more hardware based and offer innovative solutions to improve chassis geometry.

The first two products include a new range of camber bolt kits and a simple camber setting tool.

By simply substituting the original upper bolts on two bolt suspension struts for PowerAlign Camber Bolts, this allows up to +/-1.75degs of camber change.
This offers an easy fix for camber issues and a perfect add-on for any suspension bush change, or for changes to camber required for a more 'track focused' set up.

The bolts are made using a 12.9 tensile, zinc plated high strength steel. These parts are also covered under the terms of the Powerflex lifetime warranty.

They are available in 5 sizes, to replace bolt diameters M12, M14, M15, M16 and M17 covering a wide range of vehicle makes and models.

Courtenay Sport currently stock the M12 bolts, suitable for the majority of the Vauxhall/Opel range.

M12 Camber Bolts £18.89 per pair
Camber Gauge
Along with the camber bolts, the PowerAlign Magnetic Camber Gauge, PFG-1001 measures the Camber angle on the wheel hub or brake disc and allows on-car adjustment to ensure correct wheel alignment.

This is a useful tool for setting Camber angles after dismantling and re-assembling of the suspension and is an ideal track day companion.

This easy to use magnetic gauge attaches to the hub or brake disc and graduates +/- 6 degrees and comes supplied in a durable storage case.A perfect addition to the PowerAlign range and a straightforward product to supply to customers allowing them to correctly set camber angles without expensive geometry equipment.

Camber Gauge £35.94 - Available to Order

Poly Exhaust Mounts

Exhaust Mount Poly Vauxhall - Astra G/H Zafira A/B inc Turbo and VXR and Other Models
We have noticed that the standard exhaust rubber/mount used on many many popular Vauxhall/Opel applications including Astra H VXR, is not very strong and over time has a tendency to perish, stretch and split, consequently requiring replacement. Often failure can occur quite quickly, especially on a modified car.

Added to this on performance models and modified vehicles with larger diameter exhaust systems, any exhaust movement in the rubber exhaust mounts can lead to knocking from time to time, especially when the mounts start to fail.

Have you ever noticed the occasional knock on start up, or from time to time when driving? This could be an indication of the first signs of weakening rubber exhaust mounts. So worth giving them a checkover at the first signs of a problem.

So we approached our friends at Powerflex to look at a solution for us. Because none of their universal exhaust mounts were close enough in size to the Vauxhall/Opel rubber mount, they set about making a polyurethane exhaust mount as a replacement.
Exhaust Mount Poly Vauxhall - Astra G/H Zafira A/B Turbo Models
These Uprated Exhaust Mounts are manufactured from a high temperature polyurethane material in red with a Shore A hardness of 67, compared to the original rubber mounts which measures 55 Shore A.

Much stronger, more durable, with much less flex due to the material type and the reduction in the size of the centre cut-out, offering far greater resistance to tearing and rot resulting in much less exhaust movement. OE Exhaust Rubbers are prone to cracking and failing, quite often causing an exhaust knock often most noticeable on start up.

Ideal for any standard or modified fast road vehicle; these exhaust mounts are equally at home on the track too.

Road and Track tested on Astra H VXR.

The number required per car will vary but this mount will suit Astra G, Astra H, Vectra B, Vectra C, Meriva A, Meriva B, Signum, Omega, Corsa C, Tigra B, Zafira A and Zafira B where OE Rubber Mount 90466688 is specified.

Quantity Required: Varies Per Car. Astra H VXR requires 6 Mounts - 4 for the centre section and 2 for the tail box.
