Overheating with Full Race Intercooler

[OPT PRIME]

Did you ever try anything? My truck was showing 235°-240° pulling 2 waverunners at 75mph. The ambient temp was 98° and elevation around 1200ft. Without pulling a trailer I am seeing temps up to 225°.

If the outlet of the turbos is 180-220 and the ambient 98* air entering the front, that is A LOT of hot air exiting behind the intercooler where the system is trying to create sufficient Delta T across the radiator to keep coolant at a nominal value. Add in water cooled turbos and a constant load and you have a truck with as much towing capacity as your average four cylinder sedan.

The intercooler relocation is a fad and only for those that REALLY need a front bumper winch. Ford gave the stock intercooler it’s own cooling and discharge path to keep that heat load off the AC, radiator, tranny cooler, ambient engine compartment, etc.

NO one that knows what they are doing mounts a hot turbo intercooler(s) in front of radiators.

Most here are probably REALLY good with their professions, obviously. Let engineers design things

Blah blah blah. There are MANY OEM cars with stacked IC, AC condenser and radiator - with the radiator being the LAST item in the sequence. The problem is not the IC, otherwise you would see many many many raptors overheating with the relocated IC. His problem is the light bars.

Ford engineers, with extensive degrees in engineering, using the most sophisticated engineeeing software with real world wind tunnel modeling placed it on the bottom.

Nuff said.

Wonder why you swapped out all your speakers and added an amp to your stereo system then? I mean, ******* engineers and all!

Maybe. But a bigger radiator would be a quick, easy, and cheap fix, regardless. And it would provide a larger safety cushion for extreme temps, harder usage, or future mods.

Win win all around.

OP's truck has an aftermarket bumper that precludes bottom placement.

Like I said, you may be good in your field, but stay in your lane. And who stacks intercoolers and radiators? Hyundai? Fiat? The OPs truck is overheating pulling a wave runner you knucklehead. Great idea.

Like I keep saying, his problem is light bars, not intercooler.

Furthermore, a light bar would do little behind the grill. Nearly the total volume of air entering that low pressure area would still cross through the radiator albeit with localized turbulent flow higher and lower in other areas. No, you Einstein’s dropped the entire heat load of forced induction system in front of a radiator on a truck utilized to tow! Good God man. Those of you that haven’t reversed engineered your Raptor for looks consider this.

Agree.

I don't think you know what reverse engineered means, my friend. And it doesn't take much actual off road driving to figure out that the Raptor needs more approach angle.

Of course, yes, relocating the IC is going to increase the load on the radiator, which is going to make towing a 3 ton boat up a mountain in the Arizona heat outside the capabilities of the OEM radiator (which Ford engineers, wisely, built a lot of excess capacity into).

So you buy a bigger radiator.

Guys, this is really simple.
