I'm thinking of mounting a aluminium radiator on to my 69 delta88.

i still have the factory HD setup from a 350 installed.

And now 1 year later after fitting my 455 engine i'm thinking on a aluminium radiator.
engine temps on a highway crouse at 70m/h and faster in the summer will bring my engine temp to 221F tops on hot day's, i know it is low enough.
normal driving temp stay's on 176F - 194F

So no problem,

But i like them to stay at a regular temp of 194F same as flowvalve.

Is there on this forum one how did try those aluminium 2 rows?
And what type of radiator and does it fit as it should.

Saw several on ebay, did someone try these, and maybe summit.

Seek a reasonable priced radiator, that does fit my 69 delta 88 with automatic.
and that wil fit nice in the original place without modifieng the radiator suports

Thanks

 

maybe someone tried the american eagle like those on ebay? or is this cheap crap.

 

No one?,

Does anyone know what size the original radiator wil be?
Or how hit could be measured?

There are so manny differend radiators that "will fit" my 69'delta 88.

and it is to expensive to sent a wrong one back

 

Hold on, my 69 delta 455 radiator measures 34 1/2" x 18 1/2" x 2 1/2" at the end of the tanks.

Hope it helps a little.

 

thanks, the measures i think are all the same on the delta's exept of 2 or 3 row?

can't vind differend in the manuals.

but could'nt measure it in inches,

did anyone test a aluminium radiator?

becouse i heard on a car meeting the aluminium did'nt cool as much as copper ones.

i always tought aluminium cools better than copper.

 

I have one of those aluminum radiators off ebay 4 years ago. 32 1/2 x 18 1/2 in my Cutlass with a 455. When it's 90 degrees out, she runs 180 degrees all day. 180 stat. Hope that helps.

 

do you remember witch brand?

be cool is the most known one by me, ebay but also summit.

but there are also cheaper eagle brand radiators.

just curious if i need to spent a lot more on a be cool brand radiator or not

 

No I don't remember what brand it is. It was an off brand and was around $200.00. Grounded it correctly and it still looks like new inside and out.

 

Back in '69, we were still using 160 -180 degree thermostats, as 195's weren't even created, as far as I know.
According to a Pontiac Rep, the only reason it's even used, is to heat-up catalitic convertors on short trips!
Reason I asked him was my 195 stuck shut on a 86 GP while under warrantee and I installed a 180, as the dealer was 40 miles away.
He had to call the factory to get an answer.
Car picked up 4mpg, seemed a lot quicker, and even passed Illinois pollution test much better than required, on a corporate 305.
Get that 195 outa there, and enjoy the benefits!!

 

The thing with aluminum as a radiator material is that for car applications its advantage is a weight savings over the old copper/brass. The copper/brass radiator dissipates heat better than the aluminum, but it also weights more and costs more for the raw material.

For modern cars the cooling systems have become much more advanced than they were when theses cars were new. As a result the weight savings and cost beat out the dissipation qualities, not to mention as Rickman48 pointed out, it helps to heat up the cats.

In conclusion, if it were me, I would stick with a factory-style radiator, or find a nice 3-4 core aluminum radiator.

 

same as i heard,

so exept for the weight i do not need a aluminium one te get the engine cooler.

if this is so, i can ad or change my core's by a local radiator repair/build shop.

thanks,

i think i stick with the copper brass radiator,
