Cooling System
Safety The vehicle cooling system is a pressurised system and hot coolant can cause scalding.

Antifreeze content can be checked using a simple tester which assesses specific gravity of the coolant mix. Most Antifreeze also contains a corrosion inhibitor . Manufacturers may specify a particular grade or type of antifreeze to b used in vehicles. Antifreeze usually contains a coloured dye ,  the fact that coolant looks blue or orange or green etc is not always an accurate indicator of antifreeze protection . As a guide neat antifreeze to water is usually mixed at  between 25% and 50% concentration depending on level of protection required. Antifreeze coolant may also be purchased premixed.

A Cooling system pressure test may identify coolant leaks from hoses , radiator, etc.

Engine temperature problems :
Possible cooling system faults can include blocked or leaking radiator, corroded radiator, sticking thermostat, faulty or leaking waterpump,  cracked cylinder head, cracked cylinder block , head gasket failure,  leaking cylinder liners, cylinder liner height incorrect, perished or leaking radiator hoses, heater matrix blocked ,  Pressure cap not sealing, Oil cooler leaking water,

Clutch fitting
Clutch fitting on site where possible.  We have fitted new clutches to many vehicles on site including Cars Vans HGV Commercial Vehicles and tractors.

A worn clutch can make gears difficult to engage or cause loss of drive.
Faults with clutch actuation can include broken clutch cable, clutch hydraulic system leaks (where applicable), clutch release lever bent. clutch release bearing noisy, clutch pressure plate, clutch centre plate friction linings worn out. Certain machines such as tractors may be fitted with a dual clutch mechanism, one for drive and one for power take off.
