For a motor making give or take 210-215 (yes NA), is it time for a replacement of an after market aluminum type radiator. How long will my OEM half size radiator last before cracking and giving up?

 

A stock radiator, like any other part on a car will last a long time as long as it's properly maintained. If you run a decent water/coolant mix, and flush it at regularly scheduled intervals, it should last for many years. Unless the cooling fins start falling out of it or you bet blockages, you shouldn't need to replace it.

 

The OEM half size radiators do not really provide adequate cooling for higher HP B series motors. If you plan on keeping the A/C, a half sized aftermarket radiator with more cooling capacity should get the job done. If you eliminate the A/C you can run a full size Integra radiator.

Lots of people run the stock radiator and seem to get by, but that is not the optimal cooling solution.

 

ebay radiator, good upgrade for the summer. Get rid of the plastic end caps and upgrade to a 1.3psi cap

 

hmm thx for the inputs... all after market aluminum Radiators are the same? Say, koyo radiator does not perform better then an ebay radiator..?

 

I dont know specificaly, but i would say the name brands have better quality and better flow... you get what you pay for.

 

The wrecking yard where I love sells a direct replacement. Looks just like OEM but it is a little thicker and holds more $60

Gonna run with that... but if that does not cut it.. then it is full size for me
