I figure it's a standard A/C system, and I added (once) the filler from the auto parts store. The only fluid I've messed with is the A/C system. I've spent a lot of time reading AP's (Vic's) posts on what he's done, and if it didn't break his van, it's probably safe on mine. There's no telling what the stop-leak will do to it.

The engine coolant is just weird.needs that special HOAT stuff. I've also seen wear marks on someone else's crank shaft caused by having the not-so-Sprinter-knowledgeable technicians Jiffy Lube change the oil. I've heard too many horror stories on this forum about "I tried XXX" in a fluid system, and it didn't end well. I've found that the Sprinter fluid systems are soooo sensitive to the chemistry (well, it's German engineering) that I don't mess with additives.

Like many here, I'm a somewhat-competent shade tree mechanic. I have used JB Weld around the reservoir seam as my first attempt, and that didn't make a difference.Īt this point, it's not leaking enough to cause any rise in temperature or low coolant warning between drives (200 miles this past weekend for example, and I topped it off with about 2 ounces of coolant).īefore I replace the radiator, I thought I'd ask if anyone has had success with radiator stop leak and has a particular brand to recommend? Or if it's a bad idea, please let me know that as well and why. I've also used soapy water to try to find a leak, but no luck. I've searched visually with flashlight and mirror, and I can see some coolant on the reservoir toward the top at the diagonal seam, but it's not enough of a leak to reoccur after cleaning it and watching as the engine runs for more drips to develop. Recently I have begun to see a few drops of coolant leaking after each time I drive, but I can't find the leak. I searched but I didn't see any definitive info if radiator stop leak products work or are okay to use. 2006 Dodge 2500 with 314,000 miles I have replaced all coolant lines earlier this year. Hi, first time posting after almost a year of being on the forum.
