![]() They didn't have the hose in stock but knew they had it in a parts warehouse 70 miles away from me. When I first discovered what hose was leaking I called them about it. Anyone know the part number on those metal tubes (or the hoses that connect to them)?Īlso if anyone is ever in need of some hoses quick I was really impressed with my dodge/mopar parts dealer in Athens GA. I noticed the metal lines beneath the radiator are pretty rusty. Filled it up 50/50 with mopar coolant and distilled water. When climbing steep inclines it would get around 210, but this happens rarely. I should add that this van so far this summer according to my scanner normally operates at temps between 180-200F. I promise my future post won't be this long. Any brainstorming or thoughts would be appreciated. I'm half way expecting this van to break down some where along this run so I'll have a new radiator, thermostat, sensor kit, backup hoses, and tool kit with me. The show must go on! I leave on another 6 week national tour in 8 days. This van is used to transport my band around the country, we tour a lot thus sometimes I'm forced to drive it even though I'd rather work on it. Another guy at autozone told me I should retorque the head bolts.Īnyway I'm just hoping some of you can maybe throw out an idea or another test to help me get closer to what happened or what is happening. Perhaps I'll look for holes this weekend. I read about one guy who fixed it with JB Weld. I also read that the timing cover/oil filter housing (which the oil cooler bolts onto) can have tiny defective pinholes after time in it, causing oil to get in the coolant. So at this point I'm still wondering what cause the initial oil leak. Thus I cant help but wonder if there is still a very small oil leak into the coolant system or is it just the residue? Each time I get home I siphon out the reservoir tank, but it mostly sticks to the walls. However its IMPOSSIBLE to get all the oil residue out, it coats interior surfaces and sticks. But besides that no more instants of white smoke. Well take that back there was one instant: When I first got the van, I was climbing some steep mountain roads in NC at 55mph and my friend behind me said that he saw a little white smoke from my tail pipe on one of the large hills. There has been no white smoke, I have rear cam pointed at the bumper. The van is driving well, obviously it got from GA to Boston and back no problem. I was told also that it could still be the oil cooler because oil at 90 psi reacts much differently than air in the oil cooler and on the gasket.Īnyways, my engine oil looks normal, its not milky. This scared me because the culprit is not clear. I used an air compressor and plugs and looked for air bubbles as I kept the oil cooler under water. When I got home to GA I flushed the coolant system again and tested the oil cooler. Of course there was still some oily residue in the system but no more mayo on the scale I was seeing it initially. ![]() From there on the coolant looked much better. I realized that I had been too hesitant on tightening the oil cooler bolts, so I tightened them more and siphoned out the oil the best I could from the reservoir tank. I had one scary moment going north to VA where I notice oil in my coolant again. Then I drove from GA to Boston and back for a tour. So to clean out the system, I got the engine hot enough to where the thermostat opened and the MB acidic mixture got through. Funny thing is I think the MB dealership did that bc the thermostat is pretty new and I have the service records on it from the past owner. I should have pulled out the thermostat but I discovered that the lower right screw of the thermostat housing, the hardest one to get to was unfortunately completely chew up. I ran a bottle of shout gel through the cooling system and then I ran some MB acidic powered mixture through it to clean it out. I installed the new oil cooler and gasket. I made a wood template to guide the tap and drill bit. To fix the stripped bores I got a timesert kit and small ratcheting tap, and very carefully fixed the bores. I didn't know I was tightening into aluminum, it was a devastating mistake and happened too easily. When installing the new oil cooler I stripped 2 bolt bores (the lower one near the engine and the one above that). I ordered a Behr oil cooler and a new gasket in hopes that it was that and not a head gasket. I replaced it and the coolant leak issue was no more. I discovered the leaking coolant was from a bad lower radiator hose. I filled it up with water and drove home. I pulled over to a gas station and opened up my radiator cap only to find oil in my coolant reservoir tank. About 1 month ago I noticed my low coolant dash indicator turn on while driving. This spring I bought a 05 sprinter 2500 with 200k miles on it.
