![]() ![]() I would rather pay someone that I trust than force them to "make it right." And, short of watching them do it, how would I know if they did? And, realistically, if they did screw it up, do I really want them working on my coach?Īm I missing something amongst all of the replies? SCAs are only needed in engines that are typically used in commercial service and designed for quick inframe overhauls. After my interaction with them today, I am not going to back there at all. If I can get confirmation that is what they sold this shop, then I think I am safe to go with that.Īs for having this shop do the work again, I understand that from a moral outrage perspective, or making them responsible for their actions, but considering the guy on the phone (one of the owners, btw) couldn't be bothered to look up the MSDS sheets which we all know they have to have, and seemed ignorant of what they use, and that they will say they didnt do anything wrong (and I cannot prove they did, in fact, I dont think they did, they just can't/wont tell me what they put in my radiator), they will charge me to do it. According to their website, they sell OAT. I have a call out to Safety-Kleen and waiting for them to call me back. Short of that, it seems the only way to be sure is to have the system flushed and then make sure I know what it is filled with.Īs for green/yellow.maybe it is yellow, looks what I call green though, but my girlfriend and I debate about the color of golf balls being green vs yellow. If someone can tell me how to figure that out, then I know what to buy from here on. They dont seem to know and since you cannot mix SCA with the non-SCA products, therein lies the dilemma. The real question is if they put in the stuff with SCA or if they used the newer ELC or OAT products. I do not think they put the "wrong" coolant in (ie standard car antifreeze), because it is a diesel only shop. At this point, I still do not know what they put in there or how to figure it out. If they can't tell you which coolant was used, I'd insist they do the job over again after they get some coolant certified to be compatible with your engine. If the tech doing the work didn't know which coolant it was, I'd keep pushing up and up until I found someone that could tell me. The shop is required to keep data safety sheets for every chemical, coolant, etc. The chemistry in the two types of coolant are not the same, and the ingredients in gasoline engine coolant can really cause some damage to diesel engines. Hopefully if you have a diesel they didn't use coolant designated for a gasoline engine. If not, you can buy the SCA to adjust yourself. If you are adding coolant specifically designated for diesel engines, especially if it meets the minimum requirements for your engine manufacturer, it should come from the jug with enough SCA already in it. That's why your manual states a minimum SCA level - they expect it to be checked and adjusted as needed. In many diesel engines (especially in commercial service) they don't actually change the coolant as much as they filter it, check the SCA levels, and then put it back in. The SCA stands for 'supplemental coolant additive'. There are test strips you can get to check your coolant yourself. There are some 'universal' coolants for diesel engines, but I never trust anything that says it's universal to work well in all situations. If you have a diesel, then it's even more important to maintain the proper chemistry levels. So, what to do? How can I figure out if I have to continue to try to find coolant with SCA (any ideas where to get it?), or if I should use the OAT or some other coolants?Įasy solution if the shop could tell me what they put in there, but other than saying it was from Safety-Kleen, they have no idea. My fluid is green, or greenish yellow or is it yellowish green? The shop said "green is green, just add some green fluid." That sounds like bad advice and it goes without saying I am done with this shop (a busy, well reputed diesel chassis shop.) They say they get it in 250 gal containers from Safety-Kleen and it has no label on it, so they have no idea. So, I called the shop that did the work and they cannot tell me if they put in coolant with SCA or OAT or what. ![]() I cannot find coolant with SCA in it, only OAT or other stuff that says SCA is not needed and warns to not add it or it will cause a problem (gel?). Now, I need to add some coolant and my owner's manual states I need to use an SCA concentration of 1.5ppm. Recently had my coolant system flushed and hoses changed in my 2002 Monaco Diplomat. ![]()
