When we were restoring Rob’s Tiger, he wanted to keep the reservoir and the OEM appearance but wanted to get the advantage of the relocated radiator cap for cooling performance. If we could connect the reservoir to the right tank, instead of the left, this would accomplish our goal.
We contacted a radiator core manufacturer and he provides us with a custom design, hi efficiency dimpletube core assembly that meets our requirements. For practicality, we installed a vent valve at the top of the right radiator tank to allow the purging of the air trapped at the top of this tank. This radiator design has proven quite successful and we have supplied many Tiger owners copies of this improved design for almost 10 years.
