Generator Radiator Repair

Generator (Genset) Radiator Repair Specialist

Newquay Radiators and Exeter Radiators have been repairing Generator (Genset) Radiators, Oil Coolers and Intercoolers since 1982.

Our highly trained technicians have over 100 years experience between them and they carry out each job to a high standard.

Whilst their aim is to meet customer requirements, they also provide advice on any options which could improve the performance, efficiency and longevity of the radiator, oil cooler etc.

Time is money, and with this in mind, we aim to keep turn around time to a minimum.



The first thing we do is test the radiator to accurately diagnose its problems.

Pressure test to reveal a leak or leaks

Flow test to confirm a choked core

Visual checks provide further information


Based on the test results, and taking into consideration cost, longevity and time-scale, the following options are considered for resolving the radiator problems.



Filler necks

Small leaks in copper and brass cores

Top and bottom tanks

Recore / Rebuild

Fit a new copper and brass core, which is repairable if future damage is sustained

Fit an upgraded core to improve efficiency

Fit a tinned core, which increases longevity


Build a new copper and brass replacement radiator, which is repairable if future damage occurs. Usually replaces an aluminium radiator, which is non-repairable.

Our workshops are located in Devon and Cornwall and many of our customers are from the surrounding areas.

With the reliable network of couriers operating throughout the country, we also deal with customers from all over the UK.
