Cooling

Removal of the thermostat helps to reduce engine temperature, however a thermostat blanking sleeve should be fitted to maintain correct coolant circulation to the entire head. Failure to do so will cause overheating around #3 and #4 combustion chambers, with obviously disastrous results. When the blanking sleeve is used it is also necessary to blank off the by-pass hose (not found on late heads) between the head and water pump.

UK manufactured performance radiator with original shape header tank and drain plug in lower tank which doubles up to also accept C-ARA4445 screw in type sensor for use on injection cars. This radiator has 20 fins/gills per inch with 2 tubes in the core and has better cooling V shape fins

Especially for more powerful and hotter running engines. Developed using the latest technology and design for increasing air flow, utilizing just two rows of very large tubes and V shaped gills.

Screw in fan control switch required when fitting C-ARA4442 super 2-core radiator to SPI mini

13 row oil cooler with 1/2" BSP fittings. Not a vital component these days due to advances in oil technology but useful on race cars and engines that exceed 90BHP

This is the rubber seal to retain and seal GVS104 transmittor in the bottom tank of the radiator on injection cars

Silicone bypass hose that can be removed and reused many times. These seem to last forever! After a series of failures caused by poor quality rubber hoses, particularly the concertina type pipes which seem to perish after only a few months, we switched to these silicone hoses. The water pump will need to be removed to fit this hose to a built up engine but the advantage is you will never need to worry about changing it again. Supplied with a pair of hose clamps to suit

Thermostat stud for all minis prior to injection cars. It's not uncommon for the thermostat housing to be corroded solid onto these requiring it to be smashed off for replacement. These studs can also be used on the inlet manifold for HS4 and HIF carbs. Uses 5-16UNFNUT nut. Sold singly

Oil pressure warning switch. Fits all A series engines from 1959-1996. Activates warning lamp when pressure drops between 7-10lb

Long neck radiator cap, as fitted to early 850s which have a deeper filler neck on the radiator

Radiator cap for non recovery system. If own a pre injection mini then this is the most common cap to use. Only exception is early 850's which may require a deep neck cap GRC101 if the radiator is still the original factory unit. Most places will hook you up with the later recovery style cap which is incorrect and will allow coolant to escape when fitted to a sealed system

Screw on cap for twin point injection cars from 1996 on. This cap fit to the expansion tank on this model and originated from the the Mini Metro. This special cap is made to allow water /pressure to escape and should be checked periodically.

Radiator cap for recovery system. If your mini's radiator has an overflow pipe AND overflow bottle then this is the cap to use, as per SPI minis etc. Externally looks the same as a sealed system cap but has an additional seal

Factory spec copper core radiator to suit SPI minis with clip in fan sensor hole at the bottom. Fitted from 1991 up until the introduction of the twin point front mounted type.

Green plastic overflow hose that fits on the radiator neck tube and directs any excess coolant away from the wiper motor and engine bay. Sold in pre-cut length to suit

Lower radiator hose for single point injection cars

Lower radiator hose with Kevlar reinforcing fibers. Has a bonded in heater take off hose for connection to heater pipe. Excellent fitting, strong, reliable hose

Good fitting, long lasting top radiator hose for 850cc, 100cc & 1100cc minis. May require minor trimming for your application

Top radiator hose for 1275 before 1990's Cooper but can be trimmed to suit SPI etc. Kevlar reinforced for extra strength and heat-resistance

This hose is the correct length for Mini Clubman 1000/1100cc motors. Also used on early MK1 cars if still running original radiator as hose outlet is in a different position than later radiators

Lower radiator hose with Kevlar reinforcing fibers. Fits Minis that do not require a heater pipe connection. Excellent fitting, strong, reliable hose

Heavy paper gasket, goes between the thermostat housing and the cylinder head

Thermal transmitter fitted in the cylinder head from 1970 to 1990

Most minis with dual gauges up to 1969 including Cooper S Mk2 with oil and temp gauges fitted used this sender when fitted with a voltage stabiliser.

Minis before Sept 1964 except some super deluxe and pre Sept 1964 Cooper without voltage stabiliser used GTR102.

After 1969 use GTR101.

Another guide is that the gauge for this had a pointed bezel but if you have the later rounded bezel type from 1970 on try GTR101 if readings seem wrong.

Thermal transmitter fitted in fitted in sandwich plate below thermostat on twin point cars

Coolant temperature transmitter fitted to SPi cars from 1992 until 1996. Mounted to the underside of the inlet manifold

82 degrees thermostat which we have found to work the best in most cases

Fan control switch with seal for SPi Mini radiators. This is the push in type that fits original factory radiator. Controls the addition fan inside the passenger side front guard. See CDU2334 for seal to suit

High quality higher capacity pump fitted with a PPS, glass filled plastic impeller as used by Aston Martin and Jaguar which reduces weight on the bearing loading and has a triple lip seal giving a better controlled flow rate through the rev range. This pump is about 130g lighter than standard type and has the rolled edge gasket facing evolved by Rover for better sealing. Tested with coolant pumping at 10,000 rpm with no detriment to the PPS impeller, this larger impeller pump moved more coolant than the original early GWP132 standard pump and is the only brand pump we now sell
