If i currently have a standard radiator can I switch to the heavy duty radiator for extra cooling. Would it fit just the same as the standard radiator?Rick R.May 24, 2021
Best Answer:Hi Rick, I'm glad to help you out. Yes, you can upgrade it to an aftermarket heavy-duty radiator, but you have to make sure that the dimensions are the same and the location of the inlet and outlet hoses are on the same side. I hope this helps and happy shopping.

Unbeatable!!! You can’t go wrong!
Excellent radiator! The Good: Factor in the price and it’s one you can’t beat. Fast shipping and perfect fit was/is also a plus. It’s been 3 weeks since I installed it. So far, it performs better than I expected. The Bad: The only issue was the transmission lines and drain plug didn’t come with o-rings. To make it worse, I found out after completely installing the radiator and everything buttoned back up.so I had to take everything back out and start over. I will take some of the blame because I should have looked. The website says everything needed comes with the radiator, so I assumed that would include the o-rings. Summary: If it wasn’t for the o-rings I would give this a 5 star rating. With that said, I “HIGHLY” recommend carparts.com and the radiator. You are getting your money’s worth and a whole lot more. A lot more!! (Just make sure you have the o-rings before installing.
