Thread: Upgraded / all metal radiators?

just replace it with a stock replacement, if you like you can upgrade to the gtp's i inch rad. the one you have is 5/8 th's.

im using a 5/8 in my sc car, its runs the same temps.

or if he wanted to get the 1 and 3/8 one here is the link https://www.radiatorexpress.com/prod...aia_id=1303827

no, im telling you put a rad in that dont fit, like what your already trying to do.

it fits. its just a bit thicker in the core.

you dont need a larger rad either, you have a n/a car with a v6. ( not a race car) if your rad is shot a new one will be an improvement dont ya think?

and the engines supposed to run at 210 degrees. thats not over heating. its where it makes its best power and best mpg. aka made to run that hot.

good luck on your quest to waste money. you can get a nice new replacement one for like 50 bucks. keep in mind you need a trans cooler and if the lines dont fall in the same place you modding the lines now too. as well as some way to mount it. feel free to make more work for yourself tho.

and theres nothing wrong with the plastic elbows either.

Zzp has an aluminum rad, but you will need to also install a trans cooler as the one on that rad is aweful and makes the trans run hot.

very few bother up grading the rad, why dont they? cause it not needed. last you'll hear from me on this. like talking to a wall.

You wont find anything all metal like you want that just drops in other than the zzp afaik.

Here guy have fun, make sure you add that trans cooler with it

Because we are trying to tell you, you don't need an upgraded radiator. There is no benefit for it. Just buy a stock one and move on. If you don't want our opinions/help, then don't ask. Russ already gave you a link so why are complaining?

find another forum then. cause you been told already what to do, but you seem to think theres a better newer rad. and theres not, they are all made with plastic tanks. they all can crack for no reason, get used to crap breaking, you own a grand prix thats how old now? this rad lasted how long? please........


and im locking this dumb thread, good day.

unlike my car that is constantly plagued by radiator issues (poor design), the grand prix does not. the stock radiator is more than up to the task of lasting through whatever you'll throw at it for a very long time. why fix something that isn't broken?

Keeping opinions aside, please know that if you go with the radiator Eric suggested, you will need a different lower radiator hose. I believe it comes from that same vehicle.


Facts that I have learned working on hundreds of these cars:
The coolant elbows you "upgraded" are actually a downgrade. Years ago GM included the lower elbow into the alternator bracket (you called it a pulley housing). This cast elbow had a nice o-ring on it and GM started seeing a problem and quickly changed to two nylon elbows. The aluminum cast piece would corrode and when someone attempted to remove it, they often broke the timing cover where in enters. A nylon elbow can be wiggled easier in all directions as it has give. If necessary it can be broken and then removed as pieces. Those aluminum elbows, I have seen one break, they aren't super thick and beefy as they appear. Hopefully they don't corrode and cause broken timing covers, it is my hypothesis that they will.

The Caddy radiators are able to be swapped into Bonnevilles (92-99), honestly I doubt you'll get enough benefit from an all metal radiator to be worthwile, but that's my opinion.
