Before I order a radiator for my winter build I can't help but ask, is the GRI-1-25241-X for $165 really enough?

I know, I know I searched and seems that's the one everyone uses but a I haven't found a lot of feed back and since I'm running ac I really want to a good rad.

Would the GRI-1-55241-X be a better option? It has 1-1/4 tubes. Or would it not make much difference.

Car is a 4th gen lq4 with a pt88 looking to make 700+ and keeping the ac.

I'd like to know also. Is this a direct replacement (does it have every connection on the same side)?

I use it with a very similar setup. Its all in the fans. Spend your money there, the radiator is fine and fits well when stood up.

Or get junk yard factory fans and don't spend much money. People have had good results with the factory fans, ford taurus fan, or my self with dual pullers shrouded from an 01 saab 93 turbo

with AC you're going to want the 55241. its good for about a 20 degree temp variance

the week old 25241 i have sitting in a 55241 box says so . . .

ya I wasn't sure if there was a measurable difference between the two. I'm definitely planning on getting some good fans, was thinking about using factory puller fans (not sure which ones yet) then maybe a small additional pusher fan wired to only come on when I turn on the ac.

Just hate to 'waste' $100 extra if it's not needed, but don't want to buy the 25241 only to find out I could of really benifited from the 55241.

So do these two radiators have every connection that the factory have, and are they on the same side?

kylemm1002

iTrader: (6)

No. The inlet/outlets are on the same sides but you don't have a spot for the steam vent or coolant level sensor. I think the outlet size is a different size then factory.

tally, are those 2 the same dimensions with same hose attachement points?

kylemm1002

iTrader: (6)

Ya. Both the radiators I listed (and he listed) have the exact same dimensions and inlet/outlets. The 55241 has 1-1/4" tubes vs the smaller 1" tubes in the 25241.

I guess the 1-1/4" tubes are more efficient in heat transfer. I'm just not sure how much more that 1/4" of water will make?

car i used both on was a 370ci, S480, full accessory and ac street car. beating on it, temps would climb to the mid 220's and not shed the heat at all once it got warm, especially with the ac on. after the radiator swap maintained 190-200.


they also have an 85241 that has 1.5" tubes

Did you get the stand thickness 'x' or the smaller 'xs'?
One is 3" think other is 2.5" and they are the same price. Wondering if the slimmer one would gain me a little extra room.

"X"

tank to tank measurements are identical from the 25241-55241-85241, the core is a half inch thicker each (2", 2.5", 3" respectively)

I do agree with the person that said it is all in the fans. 100% true. Also as a note, it will not benefit you to have BOTH pusher and puller fans. Use one or the other. Honestly, the Griffin 25241 should be more than enough. It is almost as big as the factory radiator in height and length, but it is 2.25" thick vs the factory is only 1" thick. I would just make sure I had all of my ducks in a row for the cooling system. Use every advantage you can (Transam cover removed like in Tallys picture, correct thermostat, sufficient water pump that is non-underiven, water wetter, etc).

Also just to give you a little info, I just went out and measured my 25241, and the endtanks are 3" thick, but the actual heat exchanging part of the radiator, the fins or whatnot, is 2.25".

Tally you had mentioned the 25241 is a week old meaning you just did this swap? How does the outside temp compare to when you had the 220 temps with the 25241?

SPRAYED 01

iTrader: (22)

Basically is it apple to apples comparison between the 2? A 20 degree drop is a big deal.

fans dont mean **** if the car wont shed heat at cruising speed once it gets hot. above a certain mph (somewhere around the 50mph mark in my opinion) fans have ZERO effect on your cooling system. the radiator is a heat sink, and if the core isnt up to the task and gets heat soaked, more fan isnt going to help at all

if the car cant idle with the hood down or run in stop and go traffic without over heating, you need more fan. if the car runs up to 225-230 after 3-4 hwy blast and stays at 210+ when your back to cruising at 55+, you need more radiator. ac running compounds the effect

week old meaning used a week. i finished and was running the car i wanna say in june. that was with both radiators. probably high 80's low 90's and humid outside

Ya Id have to agree with u there. If you were able to drop 20* in the same outside conditions I'm just going to buck up and get the 55241x because I only want to buy one radiator. Trying to do this right the first time....(which hasn't been my past lol)

SPRAYED 01

**** for a 20 degree drop im going to get that one too. I was getting up in the 230 range with ac on 95 out in traffic.

Mt only issue is the 1/2 thicker part. I don't know if i have another 1/2 inch before my fans would hit the turbo
