Temp difference w/Aluminum Rads

[captainwhack]

I dont have a SC, but here is what I have
Tundra 2000 V8 Limited 4x4 135,000
I installed a leveling a kit back in 2003 (coil spacer and add-a-leaf, front and back respectively)
30" to 32" tires BFG A/T

Trailer - 2009 Jayco Jayflight 26BH (4800 dry)

UPDATE-----
I bought a new set of tires lastnight and went back to the OEM size of 30" which put me back at effective rear end of factory 3.9.
With the larger tires I was at 3.62
I noticed that my ability to climb the monster hill near my home has actually improved a little, I still cant maintain my speed, but it does not drop AS FAST (mph) as it was before.
Also engine temp is still getting up there, but not as high as it was.
I switched from 285/75(16) to 265/70(16)
I found at Napa they have a Modine 3 row that is supposed to be a HD version of the stock.

Copper brass radiators are better thermal conductors but are older in design. Aluminum radiators are better because they have MUCH larger tubes. This allows for faster coolant flow and more cooling surface area. 2 row (1.25" tubes) aluminum radiator is approximately equal to 4 row (.5" tubes) copper brass radiator. And it will be smaller and lighter.

hi, i have a 05, with a additive that dropped the temp 2 to 4 degree's. i live as you can see in south florida and i run my a/c all the time. and my antifreeze run's at 184 to 186.
so i don't reallly know if a alum. rad. will help, unless it is double the size or just larger. that would do the trick.
or put in a lower thermastat, where is will open alot easy'er.

the more air you allow to the rad, will keep it cooler, that is why i changed my grill.

i'm sure there are many other way's to lower the temp. to.
but i belive 184 with the a/c on in 90+ outside heat with the engine running is about the best it could be for me, especially playing like i do.

I have a problem where my 2000 4x4 V8 is overheating when pulling a travel trailer during the peak of the heat of day. I would like to quantify how much more the coolant is heating up.

Wow this thread started over a year ago. =) I just happened to log back on and saw there was an update to this ol thing.

Anyway I think this answer your question: ScanGaugeII - Trip Computers + Digital Gauges + Scan Tool
