Can't keep this SOB cool :(

[dville_gt]

I know, I've posted about this before. I've tried fucking everything it seems to no avail. I've upgraded to a giant dual pass radiator, added 3.8 taurus fan on high speed full time, opened up the lx front bumper, removed bumper crash bar, built a radiator box, sealed the radiator/condenser/intercooler together to promote airflow through them, built a turbo heat shield, run straight water (with 2 bottle of wetter), cleaned the a/c condenser fins, etc.

Still can't run the a/c on a hot day with out the temps slowly (but surely) creeping up to 230* where I cut it off. It will then go down to around 210-215 and maintain. This is with a 196* thermo. Oil temps climb to 240 when the coolant temps get this hot.

I am at wits end. I have literally tried everything I can think of. Brooks might have said it best when he told me the problem is shoving 20lbs worth of shit into a 10lb box, but I have to imagine that it is possible to keep this combo cool. I am considering switching the 3.8 taurus fan out for a mkviii fan if it'll fit, but I doubt that an extra ~500cfm is going to make any measurable difference, especially since I am getting good airflow as it is (it will suck a piece of duct tape through the grill opening up against the condenser with the fan on for example).

Anything you guys can offer that I might not be considering would be appreciated. I'd like to keep a/c on this car and actually be able to enjoy it.

Here is an example of how much suction the fan has pulling through the condenser.

That sucks

Does it get hot setting still or running down the highway?
Where are you getting your temp reading from?
How is your steam vents hooked up? Plugged at rear with a front cross over?
Have you verified the temp with a gun on the thermostat housing?


I see no reason it should be getting hot. My truck stays at 170-180 with the a/c on sitting still or cruising.

Wrap all the turbo stuff?

[2165 Turbo Rail]

My turbo has a blanket on it but that's all and mine doesn't get anywhere near that hot ever. Sitting still with AC on or driving with AC

I'm curious about you vapor tubes too.

Why do you have such a high thermostat anyway?

By the time it opens it's behind the ball Already

This might of been covered already, but could it be a bad temp sensor?

convert it to methanol

be sure you have that dam on the botom of the front

do you still have the factory fan on the water pump also

[SaTx04Lightning]

What size radiator are you running? Might need put in a custom aluminum 4 core to help disapate the heat better

[War Machine]

buy a 3 inch hole saw, and cut holes in the hood, and fenders til it cools down.

Hood louvers!!!!

Mark VIII fan?
Fluidyne termi style radiator?

[Rick Modena]

160 degree thermo, Ron Davis 2 core 4-inch aluminum radiator and some type of fan controller.

1: both, but worse at idle/low speed. ideal is ~50mph where the rev's are not too high but there is a decent amount of air coming in.

2: getting temp via factory sender in the front of the drivers head (reads ~230* and via an electrical autometer sensor in the back of the passenger side head (reads ~210-215).

3: Using a ls1 style crossover with all four points tied together (modd'ed the ls6 intake bottom). have the hose from the cross over flowing back into the upper radiator hose.

4: yes, although it doesn't read quite as high I assume that is due to the margin of error with the IR thermo.

Haven't done this yet, ideally I don't want it wrapped as it rust out the cross over pipes more quickly, but it might be something I'll do just to check it off the list.

Vapor tubes tie all four corners together and feed back into the upper radiator hose via a splice. thermo is the stock unit, always was under the impression that you don't won't gain any cooling ability by lowering your termo if your system is already having trouble with the higher temp thermo. i'm already just flushing water straight through it.

while the sensor might be reading a little high (depends on which sensor you trust more, the oem one or the autometer one), either of them read higher then i'd like.

i've definitely got the factory air damn on it and have modified the front bumper to bring in a lot more air then factory (as well as building a radiator box that forces all that air through the intercooler, condenser, radiator). no fan on the water pump (lsx swap), but am running a high cfm 3.8 taurus fan (~3600cfm)

radiator is 29x19x4" dual pass aluminum radiator. it is GIGANTIC.

Thinking about trying the mkviii fan, but have little hope in it actually fixing this problem (unless this 3.8 taurus fan is just totally crap and just sounds like it's moving a ton of air).

160 degree thermo, Ron Davis 2 core 4-inch aluminum radiator and some type of fan controller.

might try the lower thermo to knock it off the list, but don't really see how it'd help much since i'm not able to maintain at 196, not sure how it'd be able to do so at 160. radiator is covered and the fan controller would be nice but also not seeing how it'd be advantageous in cooling vs. high speed 100% of the time.

small pullys?

: both, but worse at idle/low speed. ideal is ~50mph where the rev's are not too high but there is a decent amount of air coming in.

sounds like it, go back to a stock lower and water pump pully and see what happens

using a stock water pump, water pump pulley, and crank pulley.
