Coolant Smell

[TRXNUT]

On an adjacent subject... does anyone have a copy of the shop proceedure for burping the system? I'm assuming their is some special process due to the two resevoirs. Maybe?

Someone can correct me if I'm wrong but I'm pretty sure its two different cooling systems, one for the supercharger and one for the engine itself and they are not connected in any way. The small reservoir is for the supercharger. Both systems have to be pressure filled.

That makes sense. Thanks!

Just saw this post and mine has been doing the same ( coolant smell when shutoff) ... but it's been doing it for months, and yesterday I decided to check for leaks and no leaks seen AND both reservoirs are full of coolant, truck was running and then shut off and still full no change, also whenever I'm driving and "stomping" on it the temp gauge goes up to halfway point ,and oscillates between 1/4 and 1/2 all the time. truck is all stock '21 and at 88788 miles .

Yeah my coolant temp will move around quite a bit too. It's been cold here (about 30deg). But the temp gauge rarely goes past the 1/4 mark. I was thinking someone may have put in a thermostat delete. I drove it 2hrs on the hwy at 75mph and the temps never made it to the 1/2 mark. It's just odd.

But to your point - There may still be a leak even if you don't see it on the radiator. It's probably in the very upper corner on the passenger side buried under the cowl cover. Vapor is off-gassing but the leak isn't big enough for liquid to come through. Should still see some residue though.

Anyone try going aftermarket? I just started smelling this today and looking at alternatives besides another OEM replacement.

I put an order in for a Fluidyne radiator two weeks ago. I was told a 3-4 week wait. The owner, Frank, reached out immediately once I placed the order to let me know the wait times. I plan to post an update after the install and initial reviews.

 

[Johnny@JustBoltOns]

Looking forward to it!

Update: The radiator arrived after 5 weeks. It was a little behind their projected wait times, but still nothing to complain about. It was packaged very well, double-boxed with custom-cut foam to prevent movement. There was one bracket that was slightly bent and did not appear to have been caused by transport. It was easy enough to bend back to where it needs to be. New rubber isolation pads are included. I'll be going on vacation next week, so I'm hoping to complete the install sometime around mid-to-end-of April. I'll post a write-up on the installation process and provide a link when it's ready.

Any progress on the install?

Life got in the way and additional mods planned caused delays but I just started this weekend. I focused first on pulling my supercharger to send out for porting. Next up is radiator. I have all the coolant drained, I just need to pull the fan assembly and factory radiator next.

I finished installing the Fluidyne radiator. Overall, I'd say it was a 3/10 in terms of difficulty. What made it more challenging was the fact that I have an interchiller installed. The additional A/C and coolant lines made it harder to navigate the factory radiator out and the new radiator in. If you plan to do both a radiator and an interchiller, I highly recommend installing the radiator first. It may be possible to complete this install without removing the front grille, but I had to remove it due to the interchiller setup.

I referred to the following manuals for removal of the fan shroud and factory radiator:

The Fluidyne comes with new rubber isolators for the bottom mounts. However, the top-mount rubber isolators on the factory radiator must be reused. Do NOT throw your old radiator away until you take them off. They are the ones that have a bolt going through them to mount the radiator to the upper support.

I found that unbolting the lower radiator mounts on the Fluidyne made it much easier to maneuver it into place. There was plenty of room to bolt them on after the radiator was positioned in the truck. Do NOT use power tools when tightening the bolts that come with the Fluidyne. I used my Milwaukee cordless wrench, which resulted in snapping one of the bolts to the lower bracket on the passenger side. I would have to take the radiator back out if I want to correct the issue. However, the rest of the bolts make it an incredibly snug fit, so I'm not concerned about it. I'll address it if I ever need to remove the radiator.

I still have at least another week's worth of work to do to my truck before I can fire it up and attest to the performance of the radiator. Honestly, the factory radiator provided sufficient cooling for my power level of 1000whp, so I do not doubt that the Fluidyne will do well. I will be making 8+ psi of boost and over 200+whp by the time I test the Fluidyne, so it will see more abuse than the factory radiator.

The factory radiator was leaking everywhere the plastic end caps met the aluminum radiator.

Let us know how it holds up. I'm thinking of going this route when mine goes out again. First one was covered under warranty, but that's long gone now. If I'm going to have to pay for one myself it would be an aftermarket one like this one. Heard good reviews about this one.

Everyone keeps saying they got theirs replaced under warranty. I was told, yesterday, that the radiator is NOT part of the powertrain warranty or any other warranty and I'd have to pay our of pocket. 2022 with 30K on it. Am I being lied to?

Yes. But, I have an extended warranty which covered it. If you didn't buy an extended warranty on a vehicle like this... you're gonna have a bad time.

It's part of the 3 year bumper to bumper warranty, also find a new dealership your current one is shady obviously
