When looking for a replacement radiator, take replacement radiator advice 
from those who are familiar with the different types of radiators available. If 
you are buying something other than what came in your vehicle from the 
factory, you will need to know the size of the inlet and outlet and the width, 
height, and thickness of the radiator.
Water Flow
If your vehicle came with a one-core radiator and you want it to cool better, 
putting a two- or three-core radiator in isn’t usually the answer. Radiators are 
built to handle the flow rate of the water through the engine block. Water 
flowing too fast never has a chance to cool down before it goes back into the 
engine. Water that never heats up enough to keep the engine at the proper 
running temperature could make your engine run cold, causing it to use more 
fuel. Also, your heater will not produce hot air. It’s important that you have 
the proper water flow, so you should always use the same size radiator that 
came with the vehicle.
Instead, make sure the thermostat is opening and closing properly and that 
the radiator isn’t full of calcium or clogged with crud. You could also have dirt 
and crud in the water jackets. Getting the radiator flushed may help with that 
problem.
Check the Core and Tanks
When you buy a new radiator, you expect it to be in perfect condition. 
However, sometimes bad radiators get by quality control, or they may be 
damaged in transport or storage. Always visually check the radiator before 
you install it for bent core fins or holes in or near the welds on the tanks. If 
the radiator is not metal, be sure to check the tanks for cracks and other 
issues.
Keep in mind that the cooling system is under pressure once the vehicle gets 
to operating temperature. You may not see issues with the radiator until you 
install it and the vehicle heats up. After installing a new radiator, be sure to 
allow the vehicle to run for at least 20 to 30 minutes and check for leaks as 
soon as the vehicle heats up and during the entire time it is running. 
Remember, if the radiator leaks all the water out and the coolant 
temperature sender isn’t immersed in water, it will not register a 
temperature.
Radiator Repair Shops
If you’re lucky, you will have a radiator repair shop in your city. You can save 
quite a bit of money by taking the radiator to them to have it rebuilt. You 
could have a new core installed on the old tanks, have new tanks installed on 
the old core or even just have the core cleaned and repaired.
As always, call around to different auto parts stores and radiator repair places 
to check prices as they will vary quite a bit. You may also find radiators that 
are less expensive at online discount stores or on auction sites. As always, if 
you are unfamiliar with the seller, be sure to check out the seller and the 
seller’s reviews before forking over your money.
