Issue on Sidewinder... need some help or ideas.

are you thinking maybe there is something with the bottle siphon that we should let it go and see if it does not get hot? I thought you were messing with me.

Correct! It may just normalize in a spot. Just like my apex. Push it out until it doesn't any more then done.

I get that but it would over heat from boost, it would not run right, it would start hard... it doesnt do any of that.

Not mine! Runs like a champ! Seriously! I wouldn't know it was slowly filling the oil tank up with coolant. No mis-fires, pulls hard. starts easily.

I has a vehicle once and the plastic overflow jug was cracked and it would let you fill it up and never leak, but when the system built up pressure it would push it out when hot. Never showed up in a pressure test, because the overflow tank is outside of the pressurized area. Probably not your problem, but just sharing in case it sparks another idea.

All comments are good and worth a check.

I will add a couple of notes since this issue is on my sled.

I also need to add coolant to the system every time once cooled and the reservoir is empty . By that I mean take off radiator cap, remove bleeder bolt on other side and raise the sled up about 5" on the left side of the sled when sitting on it to add coolant until it comes out the bleeder hole making sure all air is out of the system. It takes about a cup to a cup in a half until full. I then add the coolant to the reservoir.

I should have also mentioned oil level does not change and is not milky.

no sweet smell from the exhaust when warmed up?

Check those hose clamps on the oil cooler. Heck just tighten them up, it weeps out of there so slow that it doesn't have a chance to drip.

sounding like the uv light might be the way to go. that is how a guy found one on a transport engines. it would crack in the exh side of the head and burn all the coolant up with no smell. he found it with the dye in the exh and chased it back until he found it.

I would think if the overflow tank was broken, there would be antifreeze all over and that would be where the fluid was going. I don't think there is any visible leaks. That's why this is so confusing it's useing antifreeze but no one knows where it's going.

I would say you also have the same problem you shouldn't have to keep adding antifreeze.

Not that it should make a difference but are these sled stock or tuned.

this sled has a multi map precision tune and was bought used with tune. He’s been running it at 250 but any tune eats fluid.

The smart hose in tunnel (exhaust side ) has been well check ? sometimes they leak slowly:-/

Short hose?
