It should fit. I use a radiator out of an 89 iroc. My friend used one out of an older Chevelle. You just have to custom make some mounts and use electric fans

 

YOU WOULDN'T HAPPEN TO HAVE ANY PICTURES OF THE MODIFICATIONS THAT YOU DID TO THE RADIATOR SUPPORT.

 

copy and paste my yahoo briefcase addy. you can see the radiator. there's no mods to the rad support. it just sits right up flush and I have it bolted down at the top. i can take more pics if you want to see it. it's kind of ghetto but it works well and was cheap.

 

Unless you're running a lot of horsepower, a factory 4.3 S-10 radiator will work without any mods. Depending on what mounts you use and where the engine sits you may also be able to use a flex fan instead of electrics.

 

WHAT IS THE TEMPERATURE THAT YOUR TRUCK RUNS @. JUST WANT TO MAKE SURE THAT IT IS NOT GOING TO GET HOT IN TRAFFIC.
THANKS

 

I'm running dual electrics with I think a 160F thermostat (can't remember). Runs at that all day, when stopped at a red light or any really long time, it gets up to about 190-200, but once going again it dropes right back down.

finally someone that agrees with me. i am also running the stock 4.3 radiator in my truck, and it doesnt go much past 160-170 in this 95 degree heat. i have 2 camaro fans pushing btw..

 

finally someone that agrees with me.

Just going with what I know works. BTW these only cost about $150 new if you don't have one. Alot cheaper than having a custom one made...most junkyards will have em...just make sure you flush it out good.

 

If you can get what you have to fit, use it. It's not necessary to spend money on a custom radiator or a vette radiator.

 

I AM GETTING READY TO PUT A '76 V-8 OUT OF A MALIBUE IN TO MY '87 S-10. I HAVE THE RADIATOR THAT WAS WITH THE MOTOR AND IT IS ONLY ABOUT 2 YEARS OLD NOTHING WRONG WITH IT. MY QUESTION IS CAN IT FIT IN PLACE OF MY 2.5 RADIATOR JUST WITH MINOR MODIFICATIONS TO MY TRUCK OR DO I JUST NEED TO GO GET A CORVETTE RADIATOR.
HELP ME OUT GUYS!imp:

If your 2.5L rad is an aluminum core (not copper) keep it, don't replace it. The 2.5L four banger rad has the hoses on the same side as a V-8 rad. The rad will work fine if you run a 195degree thermo and a good direct drive fan. Wouldn't hurt to put a pusher electric in front too, but not necessary. My buddy's truck has a V-8 with the four cylinder rad and it runs between 190-210.
