Our Radiator Repair Services

At N and J Automotive, we also deal with all aspects of your cooling system. Here’s what we offer:

Radiator Leak Repair
We search for leaks thoroughly and then repair them if they are in the radiator core, hoses, end tanks, or fittings.

Radiator Flush and Coolant Replacement
The old coolant becomes acidic with time and disintegrates slowly. We empty the system to the last drop. Then, refilling is done using the proper manufacturer-specified coolant.

Radiator Hose Replacement
Cracked or bulging hoses result in overheating. Replacement of upper and lower radiator hoses and clamps is done with efficiency.

Thermostat Replacement
The malfunctioning thermostat will not allow the coolant to circulate properly. Our mobile service involves testing and substituting it at the shortest time possible.

Water Pump Inspection and Replacement
The water pump has the function of circulating the coolant. In case of failure, it will soon overheat your engine. We check it as part of every radiator job.

Radiator Cap Testing and Replacement
A faulty cap causes pressure loss in the cooling system. It’s a small part but an important one — and we test it every time.

Full Cooling System Diagnostics
We run a complete pressure test and visual inspection to find any hidden faults before they become bigger problems.

Radiator Replacement
When a radiator is too far gone to repair, we source and fit a quality replacement unit — OEM or aftermarket — at a competitive price.

Frequently Asked Questions

Everything you need to know about our services

modern car ready for servicing and repair
Do you carry radiator parts in your van, or do I have to wait?

We take the everyday stuff – hoses, caps, thermostats, coolant. We take the old one and put a new radiator in its place, the same day or the following morning.

The average time for jobs is 45 minutes to 2 hours. In a fast hose repair, it is more immediate; a complete radiator replacement is slightly longer. Either way, we try to get it done in one visit.

Be careful, do not open the cap when the engine is hot. In case it is cooled to the full extent, it is all right to add some clean water as a temporary solution.

Yes, we do. We labor without being requested within the warranty period. We will be back to repair it free of charge.
