Every Driving Situation is DifferentĪ daily driver is different from a weekend warrior, and a weekend warrior is different from a race team or off-road club. It’s also how our reputation of being the best additives on the market has been forged – by proving real results that far surpass what typical additives can provide. We do it because it’s how we’ve become a global bestselling brand. We know this because we stay on top of emerging automotive trends diligently. When engines change, new transmissions are developed (like continuously variable transmissions (CVT) and dual-clutch transmissions (DCT)), what worked in the past won’t work now. The only way to stay on top of the game is to have a chemical engineering team that is a bunch of gearheads at heart. If anyone has an explanation or solution for this I would greatly appreciate it.When you’ve been in the chemical additive business for over a century, you learn a thing or two.Įngine, transmission and fuel system technology changes – big time. This is the only theory I can come up with that makes sense of the temperature variable. Or at least only one time after a 5 hour trip did I notice it leak a little bit when it was 80 to 90 degrees.īut the coolant level never really changes, never had any puking issues, power seems fine, and never any overheating.Īnyways, with 80,000 miles on it I'm just wondering if this problem is due to stretched studs, and when its cold out, the heads and block constrict, resulting in a gap at the headgasket since the studs are longer than they should be. Now the mystery is, when its around 40 degrees or above, it doesn't leak. So every night so far it leaves a wet spot of coolant on the ground. Now this winter, I'm in a colder climate and its been consistently around 20 degrees at night. Looking under the truck it appeared to only come out of the passenger side rear corner of the engine around where the head gasket should be. Last winter on some really cold days I noticed coolant on the ground after I had run the truck and let it sit out either overnight or at least had cooled down. I have what sounds like the same problem. I did not want them to reflash but they did it anyhow.Īny help or advice would be appreciated. They did this when it was in for the leak. 06E17 control module recalibration, reprogram PCM. They put pressure on it again and found no leaks They have it back and are stil checking it. I live in Des Moines Iowa with freezing temperatures. (At least not that I know of) I never smell anti-freeze. It does not leak while driving (the coolant resevoir is normal range. It does not leak after driving and warming to normal operating temps. I check it a day later and no further leaks.

The dealer put it under pressure and found the factory hose clamp leaking then put on a screw type clamp.

I took it in and they replaced a 48 cent hose clamp with a $180 labor charge. The gauge always stays in the normal range I have a 03 6.0 with a coolant leak right front engine lower.
