Commercial Radiator Repair

Commercial Radiator Repair Specialist

Newquay Radiators and Exeter Radiators have been repairing Commercial Radiators, Intercoolers, Oil Coolers, Heaters and Fuel Tanks 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.


Where available, a radiator with an aluminium core and plastic tanks can be supplied. This sometimes works out to be a cheaper option. ​
