Thoro Flush

Thoro Flush is the best commercial grade product for removing all traces of any Ethylene Glycol based Radiator Fluid. It removes rust, grease, and sludge to make your engine cooling system perform better. Very expensive repair bills can be avoided by using Thoro Flush at least twice a year. Regular application of Thoro Flush to your automobile helps extend the life of your vehicle, reduces the possibility of a clogged heater core, and helps keep the cooling system fluid flowing through out your vehicles engine and radiator.

Thoro Flush is a 'Must Have' if you are planning to repair a head gasket leak or before using any kind of a cooling system sealant in your vehicle. Using Thoro Flush prior to applying a sealant will insure that all passage ways are free from near obstruction that could cause the sealant to plug an area of the cooling system that you don't want plugged. Clogged Heater Cores can be the direct result of NOT using Thoro Flush in your cars cooling system, especially prior to using a sealant. If you use additives to your cooling system, your oil, or your gasoline, you should also use Thoro Flush on a regular basis to insure that your cooling system remains in top working condition and is free from any contaminants.

Ceramic Motor Seal

Have you been advised that it is due to a cracked or porous, cylinder head or cylinder block?

If you should decide to have your engine fully reconditioned, it could potentially cost you thousands of pounds.

There is an alternative… Before you go to the trouble of stripping the engine for further inspection, why not try circulating ‘Irontite Ceramic Motor Seal’ through your engines cooling system?

Professionals in the engine rebuilding industry have used 'Irontite Ceramic Motor Seal' for over 40 years, to resolve engine coolant leakage problems.

'Irontite Ceramic Motor Seal' is an inert viscous fluid, free of vegetable matter, unaffected by heat or cold, but possessed of an unusual affinity for cast iron, copper, bronze or aluminium.

Following circulation in castings containing cracks, crevices and open pores, ‘Irontite Ceramic Motor Seal’ cures “iron-tight”, as the chemical sealant actually integrates itself into the cast iron, copper, bronze or aluminium casting to which it has been applied.

No specialist knowledge or tools are required, as full and easy to follow instructions are printed directly on the bottle.

Unlike other products this is a permanent repair and does not need to be re-done if you change your coolant. It is ceramic based and so can withstand the heat and stresses of a modern water cooled engine.

It is designed to repair cracks up to 0.50mm wide.
