Failed Intercooler

My intercooler failed and started leaking coolant into my intake. When it first happened,
there were no warning lights or codes that popped up, engine just ran funny. I limped back to camp and let it idle for a few minutes to cool down, then shut it off. It was night time so I waited till the next day to try and start it with no luck. Started checking for problems an noticed the coolant was low, I added coolant and the engine started, but immediately threw up the check engine light and two misfire codes. Also started belching white smoke from exhaust. When I pulled the intercooler, the intake was full of coolant. I cleaned out the intake and ordered a new intercooler. Is there anything else I should check before starting the engine, after I install new intercooler?

I have 2084 miles on it currently. I have had heat issues before on long, steep trails when the outside temp is 95°-100°. In fact, I added a reflex secondary cooling fan that I can control when it's on and when it's off just for times when it starts to get hot. Fan makes a giant difference in the heat, but it was night time and only about 45 ° outside when the intercooler failed on me. I didn't get any warning lights or fault codes, the motor just sounded like it was drowning. I limped back to camp and actually let it idle for a couple minutes before I shut it down in order to cool the turbo. Engine temp was only at about 189°. It wasn't until the next morning that the engine wouldn't start and it threw up the check engine light with two misfire codes. That's when I found it was really low on coolant. I filled up the coolant and it actually started but was belching out white smoke, so I shut it down. Starting doing research and narrowed it down to the intercooler. I went with a C&R racing intercooler. They are supposed to be one of the best. Website says they are up to 30% more efficient than OEM or other manufacturers. I am hoping it is worth the money I spent on it. I'll be sure to post the outcome, once I get it back together. Keeping my fingers crossed that nothing else was damaged.

No problems so far, I have only been out once since I installed it and went about 160 miles of some hard desert driving with no issues. Installation was pretty simple. If you get one, be sure to fill it with coolant before you install it. I used the plastic protection caps that came with it when I installed it. Those were good enough to keep coolant in it during the install. Also be sure to clamp the hoses, in order to loose as little of the coolant as possible during removal and installation. Purging the air out of the system is a pain in the butt. All the videos I saw on the Internet made it look really simple. In reality, it was not. I had to remove all the heat shields around the turbo and the little vent bolt was still tough to get to. It also gets coolant all over the exhaust and down the back of the motor. Bottom line, I'm very happy with it.

I have a 18 xpt with 2300 miles. I have somethings done to mine one being a split coolant tank. My intercooler is stock and this trip I noticed it missing and breaking up but no codes. I checked the coolant the next day and noticed the intercooler side was empty! I guess having that split tank saved me from dumping all the coolant into the engine! I'm not sure which intercooler will be going in but it won't be a polaris one! Any suggestions?

None of them are as good as the stock unit, but my pick would be the BC. I've been running one for a couple years now, specifically to get rid of the known failure point of the OEM unit. I did a before and after on the same day and although the BC started out cooler, the temperature rise was higher than the OEM.

Just stay away from those replacement offerings that do not use the correct core for the job... There's quite a few (or at least there was).

Are you still running the stock coolant tank?

It still has enough to hydro lock a motor if the crack is big enough to dump a lot of coolant at once.

Either way, I think we are past that... You've had failure and you need one that won't fail. I'd change your oil as well.
Yes but atleast it's not all of the coolant! Like I said I couldn't see the smoke but saw the pre and post tb Temps going up! These systems must be very wide open as far as setting a code cause mine still hasn't set one yet!

It won't set a code as far as I have seen, it will reduce boost and timing based on post intercooler charge temps.

Modelled EGT does not get calculated from charge temps, just load and RPM, so it will not richen fuel mixture based on high charge temps.

I don't disagree that separating these systems is ideal, though I don't like any offering out there (particularly connected aluminum cans) and the crazy prices they want for something so simple. I think I'd rather take a turbo reservoir off a turbo Subaru and repurpose it for nearly free, and it would be plastic, not metal.

Mine had times it was breaking up but no misfire codes. I know some systems are designed with lets say more or less tolerance before it will set codes. The moroso one I have atleast has a gap between the two anks so the temp won't directly transfer to the other tank. As far as price goes yeah it wasn't cheap but then there's more expensive ones out there too!
