Methanol/water injection has been mentioned a couple of times in the past on this thread. I’m curious if anyone ever actually did it and if it helped at all with our cooling issues?

Mine had a cracked exhaust manifold.

I’ve already tried this, the results were underwhelming.

Don’t do that, the coolant goes from oil cooler to egr cooler.

Looking at the coolant lines going into the oil cooler, one comes from the block under the exhaust manifolds and the other goes to the egr cooler. I used the line coming from the block. I tried to get my temp gun in there to get a solid delta T but it’s way to tight. Logic tells me supply...

I went from the block into my aux cooler and then into the factory oil cooler.

Thanks, I tried coming out of the water side of the oil cooler into an auxiliary cooler and only saw about a 3* difference while towing. I used one of Derale’s larger coolers. I’m now skeptical that Bulletproof’s larger radiator is going to make a difference.

What fittings go into the cooler? Is it boss-oring?

Did it this weekend, I’ll be towing through the Rockies this weekend and will report back later next week.

Bullet Proof Diesel

Power tank all the way, 37’s in under thirty seconds, air tools, and take it with you with your primary vehicles. Unless you’re on a two week trip airing down every day you are fine on a 10lb bottle

Would any of you happen to have a diagram of the cooling system?

I’ve been running 4.56’s for a year now, they definitely make the towing experience nicer and crawling off road, however around town and on the highway I feel like they are to low and I’m on 37’s. If I were to do it all over again I’d go 4.10’s

It appears that the inlet is the nozzle is the one with the 90* turn, it’s comes directly from the block. The outlet goes around the back of the engine to what I’m guessing is the egr cooler (key word is guessing, I can’t actually see where the line terminates). Outside diameter of the hose is...

I have good line of sight to mine, sorry for the blurry pic.

Do we have any idea which water port is the inlet?

it would definitely add coolant capacity as well as surface area, I also like the idea of not tapping into oil Incase of a leak.

This is a great idea, I feel it has more merit than anything else brought up to this point.

Have any of you experienced derate after getting the DEF recall flash?
