5.3L running original radiator. Will it work?
I was wondering if my original, leak free radiator will work with my engine swap? I have soon new stuff to mount to it!

Re: 5.3L running original radiator. Will it work?
I am using my stock 4 core in my 72 Jimmy for a few years now with zero problems. I am also only using a clutch fan.

It depends on which radiator you have. There are two core, three core, and four core Radiators. LockDoc

Re: 5.3L running original radiator. Will it work?
Even if it is leak free... doesn't mean it is free flowing. 40 year old original radiators can hold a lot of crud over the years. You might wanna take it to a shop and have it rodded out, or maybe even a recore.

Re: 5.3L running original radiator. Will it work?
Look at it from the back side where it joins the tank and count the rows forward. You will see obvious rows of tubes.

I ran mine on a 2 core for years without any issues.

Re: 5.3L running original radiator. Will it work?
Thanks guys I'm going to check tomorrow. I figure it's a two core because my truck originally came with an inline six

Re: 5.3L running original radiator. Will it work?
If it's a 6 truck it probably has the 2 row narrow core unit.
Either way, if it keeps the 6 cool you'll be fine. LS motors run very cool. |

Re: 5.3L running original radiator. Will it work?
I just installed a lq9 6 litre in my 1968 c10. I thought I would try the stock two core rad. I also am using Evans waterless coolant. I have a about 1000 km on it and no problems so far.
