That locates the top of the radiator to the body of the car and also contains the mountings for the two (air-con) fans is still available from Unipart under P/No. The final job is to move the low water level warning wire to the tank from the left wing to the right one. Suitably sized water hose incorporating a 90 degree bend. The hose from the tank to the radiator is a little more difficult but Henry Ford came to the rescue with a If the correct tank and mountingīracket cannot be located then the existing one can be used but the mounting bracket will not sit squarely. To drill three holes in the correct position in the right hand inner wing and bolt the assembly in place. Although not now available from BL, a little diligent searching in a scrap yard produced the goods. the tank and bracket fitted prior to VIN200000 were on the same side as the TR8Ĭonfiguration. The partial flow tank causes no problems as, again.

Triumph tr3a coolant capacity mods#
New core and carrying out the mods cost approximately £130 and the sensor £11 -not bad for peace of mind! The assembly was then pressure tested prior to fitting to the car. These are freely available and fit a standard sensor boss. Left hand top side of the radiator to enable a TR8 type temperature sensor to be fitted, the original is still available under TKC5532 but I have found that its temperature range was incorrect so I bought anĪfter-market sensor with a range of 82-92'C. The next stage was to fit a threaded boss to the We found that the TR7 Aircon 3 row supergill core with 14 fins/inch to be quite adequate. Should be fitted with a new core to ensure there are no restrictions. Unsoldering the existing outlets, but by fitting larger ones it was felt that the strength of the side tanks would be locally reduced, so the correct diameter sleeves were fitted. Next the diameters of the TR8 (SD1) hoses were compared with the TR7,Īgain bearing in mind a reasonable safety factor built into the radiator it was decided that the TR7 outlets could be sleeved without causing an unacceptable restriction to the flow. First we looked at the comparative flow rates of the TR7 and TR8 radiators, there was only a small difference. This, of course, is the same configuration as the TR8, but the hose diameters are different. When viewed from the driver's seat and the bottom hose exiting from the light side. The early FHC's up to VIN200000 were fitted with radiators having the top hose exiting from the left side Of the radiator, but make sure it is rotating in the correct direction -air should be drawn in from the front of the car and blown over theĪs an alternative, I would like to suggest a method that I have used for mounting the radiator, and the fitting of electric fans andįirst the radiator itself. As an alternative, the usual Kenlowe fan kit can re mounted on the front

Therefore, the original TR8 systemĬan be incorporated into the conversion. However, I have managed to find someone who is prepared to re-manufacture- this part for about £50. Regarding the viscous fan arrangement, this again is availableįrom Rimmers, with the exception of the crankshhaft extension drive ERC 1519. is approximately 1/2" deeper than the original but does not cause a problem in this application. Radiator, although offered to TR8 specification. This is the simplest method and Rimmers now offer a complete kit for this application. Radiator to re fitted to the car in the correct position but without the benefit of the forced cooling system offered by BL.

However all the leading Triumph suppliers can offer a re-manufactured version of the Non Air Con type: bracketry. The viscous fan mounting cone and the electric fans are now NLS at Unipart. In both cases, the original radiators are no longer available. Originally the TR8 was fitted with two alternative cooling systems: 1) Non Air Con type -which incorporated a fan and viscous couplingįitted to the crank-shaft pulley, or, 2) Air Con type -which incorporated twin electric fans on a framework between the radiator and engine. However, as some of the original TR8 parts are no longer available, it is often necessary to modify existing parts. the conversion of the cooling system to V8 spec is basically a nut and boltĮxercise.

As the TR7 was originallyĭesigned to incorporate the Rover V8 engine.

This is another job that can be completed, off the car, before the major part of the conversion and a trial fit carried out by only removing the TR7 radiator.
