Radiator replacement

[sparc179]

I was told by an "expert" to replace the radiator of our CR-V 98 with a bigger one. He claimed that it will yield better fuel economy. I asked him why since the radiator is bigger and heavier. He couldn't answer.

I simply use what is installed. My recommendation is, use the same specification that came with your car.

Because a bigger radiator will dissipate the heat faster, creating a more efficient way for the engine to operate optimally? Haha, just guessing not actually stating.
