Aluminium Radiator TR7 all comm. numbers prefixed ACG/TCG up to VIN200000 with plastic expansion bottle or right hand mounted steel header tank, fitted from 1975 to 1979.

This aluminium version is 50% lighter and offers 1.5 times better efficiency than the standard copper and brass cores. 
Later cars from VIN200001 were fitted with radiator RTR5483-2. See below

 

As well as all the usual features, a boss is fitted in the bottom tank to allow fitment of a thermo switch to activate an electrical cooling fan.

This radiator can also be supplied painted black with a special paint that will not significantly reduce cooling ability. This covering minimises the effect of having the core powder coated, it does still have a negative effect, loseing between 2-3% of the cores efficiency. 

A small extra charge will be applied should you with to have this covering applied.

Raymond asked us to supply a radiator with a wet box and painted black. He had this to say about it: -

Just to let you know that the radiator got here in good condition and looks beautiful; very nice welds and good looking paint. It was definitely worth the wait, I hope to get it installed soon. Thanks again.
