85 burb meets 6.0 lq4

[68GMCCustom]

sounds like it could be a 3, or maybe 2 core. you don't have to go aluminum to handle that heat...consider the big block trucks. a good 4 core and plenty of air movement thru the fins should keep the temps down.

[85burb]

It is a 2 core but the tubes are 1 inch wide insted of like half inch like old rad is. The core part is 2 1/4 wide. That is much wider then stock. I just bought it so i will let yall know how it works out. Cant wait.

[68GMCCustom]

I meant how many was the radiator thats in the truck...not cooling enough. I saw the aluminum one, and that's getting to be a standard config for them.

[85burb]

I am not sure how many. It is only 1.5 inches wide so maybe 2-3 core. I have never counted.....Was going to today but could not get cap off. It is one of them fancy thermometer types and is extreamly hard to install.(not going on new rad) I was just going to buy fans and a shroud untell i seen mine was leaking.

[85burb]

Rad came in today. Fans and shroud should be here early tomorrow. Not sure how i am going to mount it yet i guess i will have to see when i install it.

[68 TT]

How close is it to the size of the stock radiator?

The core is the same i guess it says. The core width is about 1 inch wider. Maybe i will install it sunday. Or atleast take the old one out and see what will be needed to make this one fit.

[68GMCCustom]

That ought to keep it cool!

[85burb]

If i ever get it in. Have ben working on it for a few hours now. Got old one out in like 5 mins. Did not have as much coolant as i was expecting in it but was not low. I guess i am just used to having to fill 3 5 gallon buckets when draining coolant at work. But i need to find some lower rad bushings and long bolts to mount shoud and short ones to mount fans. It is not exactly a bolt on deal i guess. I wish it came assembled. Hope to morrow i get it in.

[68GMCCustom]

that's part of deviating from stock....things aren't always as plug and play as we'd like them to be!

[85burb]

Yes that is part of the fun. I just need to bolt it in and bolt the fans on and figure out how to make my efi ecu turn the fans on and off and i will done. I just hope i didnt remove the wires.

[85burb]

I got it installed and running. Holy cow does it cool off fast. I have fans kicking on at 210 and off at 185. I can not change the off temp. The only way the efi controlls it is comes on at whatver you set on at and turns off 20-25 degrees cooler then on temp. Thermostat closes at 195 so they never turn off. The air coming threw fans and rad is cold. Any one know what temp the fans are supposed to come on at? Will post pic later.

Here is reallt crapy cell phone pic in the dark.

Today was a historic day. My little girl tightined here first 4 bolts today. She also inspected his under carage with my flash light. I will get pic uploaded.

good read, thanks for sharing. I would love to yank my BB and put a LQ9 in my burb

Stock GM dual fan setups run one fan as primary and the second comes on at a higher temp or when you turn on the A/C. Any way to set yours up that way?

that's how mine is. has a relay for each fan. fan 1 (low speed) is set for key on. fan 2 (high speed) is activated by the adjustable temp. switch w/probe, or by the manual switch I have on the dash. 2nd relay will also be connected to an a/c compressor one day.

[85burb]

I will keep them the way i have them set up for now. I really dont want them on all the time. I may do something in the way of a manual swith tho. I will wait tell summer to make adjustments i guess. Thanks for the input.

[85burb]

Well i found out this fuse is no good. Was at the drive threw light park last night and about half way threw we all smelled a burning smell. Temp was fine. So i kept going. Then afew mins later when fans were supposed to be on i relaized what was the smell. And buy that time there was no place to stop. So i turned heater on full blast and hoped for the best. About 15 mins later temp maxed out the 260 degree gauge. Finally we were at the end. So i punched it and hoped to at least make it home. Temp went to normal when driving and oil psi was at 60 when driving. So i looked at the wiring and found my fuse had melted. I guess it was a crappy fuse. Installed the new fuse holder and bigger fuse. Test ran it for 45 mins fans kicked on and off 3 times and did not blow new fuse. So i will be ordering some water proof fuse holders and relays. I will wire them seperate. One relay and fuse per fan. Both turned on by ecm.

[68GMCCustom]

thats how mine are.....one relay per fan.

Did you have to modify your motor cross brace to clear the oil pan?

Nope. I used dirtydingo mounts. They lift motor .5 inches. It just bearly clears. Has not hit it yet tho.

[85burb]

Well i changed the oil today and will take a sample to work and run it threw out oil analysis machine and see if any things are wearing. Sometimes working at a diesel shop is handy!

[85burb]

I ran my oil sample today. The only thing that is hi was soduim levels. It says it can be a oil additive or coolant. But the glycal level was 0 ppm. Water was less then 0.1 ppm and no signs of any kind of metals wearing at all. So over all pretty happy and sad at same time......lsx 454 will have to wait i guess.....
