Fits most Lotus models 1996 onwards with or without air conditioning.

Dimentionally identical to our aluminium upgraded radiator ( 43mm core) except the end tanks are divided internally.

The water remains in the cooler for longer as it has to make three seperate passes of the core face.

Hot spots are eliminated as the water is forced to take a specific passage backwards and forwards across the core face.

The standard Elise radiator has plastic end tanks which are prone to expanding and leaking under pressure.

If you are racing or are a track day enthusiast we recommend our FULL Aluminium Radiator; Specifically manufactured for us as a direct replacement and built to the highest standards using F1 technology.

This has a larger capacity, more cooling fin area and aluminium end tanks so it will not burst even at substantially higher temperature / pressure.

It is more efficient so you will notice a drop in your usual running temperature.

We have fitted one to a supercharged Elise (which had temperature problems) and this radiator reduced the usual temperature from 93 degrees to 86.

We have also fitted one to a Turbo'd  Elise along with several race cars; all now run an efficient operating temperature.

Another plus point is that we bond our laser cut side mount channels into place; this we find, allows the radiator outer shell to absorb vibration without stressing the core section.

These radiators have been extensively tested on 330 BHP Audi powered cars (running temps stable at 76 degrees) 300 BHP VX Turbos (running temps down from 88 degrees with 200 BHP to 84 degrees with 300 BHP) and many high powered Honda conversions.

All slots are there for twin or single fans, no drilling is required.

Can be supplied with one of the following Fan fitting options.

  • Single Fan Mounting Kit consisting of 316 marine grade brackets, rivets, stainless steel fixings and genuine Spal plastic fixing brackets.
  • Twin Fan (Non-Aircon) Bracket Kit consisting of 304 grade stainless steel xylan coated brackets and stainless steel fixings.
  • Twin Fan (Aircon) Bracket Kit consisting of genuine Lotus powder coated brackets and stainless steel fixings.

N.B. Fans are not included, you can find them in the related products below.

Please note, you will need to retain the plastic mounting brackets from your original fans (Non-AC) as they are not available as a separate part.
