How To Picked The Best Radiator For S10 V8 Swap?

Now, you have read that so far, then take a few more minutes to get the before-buying facts. You may find many radiators in stores but all may not fit and be compatible with the small block V8 engine of the mini trucks Chevy S10.

Here we show you the complete buying guide for the S10 V8 radiator with favorable considering points.

Let’s dig out!

Vehicle Replacement Fit

While buying the radiator, look for the exact fit and size to Chevy for perfect fitting. All radiators will not fit the Chevy V8 engine as these are the modern small-block engine containing small spaces.

You can match the OEM part number from the old radiator to get the exact fit or check the vehicle manual for the recommended size.

Radiator Type

There are mainly two different types of radiators available. One is the downflow radiators, and the other is the crossflow.

In the downflow radiators, the tanks are in the bottom and top part of the radiator rows. These radiators tend to be a little large in size and need more space to fit in the engine.

The second one is the crossflow type radiator. The tanks here are on the left and right sides of the radiator tubes. These radiators are somewhat small in size, so modern engines like the small block V8 are suitable to fit this radiator.

So, for the Chevy S10 Swap, choose the crossflow type radiator for a direct fit and perfect transmission fitting lines.

Number of Rows

The core number or the rows number is also considerable for better heat radiation. The dual-core radiator means to have two rows of tubes. These are also usable for the S10 V8 conversion radiator.

Some come with tri-core or three rows featuring an increased heat dissipation area. You can pick them if your budget permits. Some modern radiator comes with four rows that also tend to be high in price better performance though.

The Material

The material is essential to look for durability and long-lasting features. You will find both Copper and Aluminium radiator. Among these two materials, the Alumium made radiator is more durable and stronger than the Copper one.

Again, in the Aluminium radiator, there is also variance. Some are made with pure Aluminium – the Blitech radiator or advanced Billet Aluminium such as the radiator from AlloyWorks.

The more improved material, the pricier it will be. But thinking about your engine performance, you should buy considering the quality, not the price.
