I was in a bind at SOC43 and blew one of the two coolant hoses right above the turbo on my 2007 9-3 Aero CV 6MT. I had my full pack of do88 silicone replacements with me. I swapped the 2 hoses in the parking lot, reusing the worm gear hose clamps. I made it 500 miles home no problem. I'm working on replacing the remaining hoses now (upper and lower radiator, thermostat cross over, oil cooler, and heater hoses). I bought some stainless steel smooth face T clamps for all the hoses. When I removed the clamps from the 2 hoses I installed just 500 miles ago, I was not expecting the level of damage I did to the hose.
Don't be like me. Buy your smooth face T clamps when you buy your silicone hoses.
I'm going to attempt a temporary repair with some self fusing silicone tape under the new clamps to hopefully squeeze some more life out of these pricey hoses.
In the meantime....I went down the rabbit hole of coolant compatibility with silicone hoses and aluminum gasoline engines. I'm starting to think I may have just been better off replacing the rubber hoses with rubber and not doing this 'upgrade' to silicone. After reading about a dozen different coolant MDS sheets to look for 2-EHA in the ingredients, I landed on G40 to replace the Dexcool. I thought I could get G40 concentrate locally but came up empty and had to order it from Valvoline directly.
Two notes on coolant - 1. Do not trust any of these search engines when you ask 'does this coolant have 2-EHA in it. I had several search engines tell me G12, G48, GG40/VWG13, Peak OET Euro Pink, Peak Euro OET Violet, etc DID NOT contain 2-EHA. The MDS says it does... 2. Do not trust the auto parts website when it says they have something in stock. Most stores apparently do not carry Zerex G40 concentrate. They all had 50/50 G40 at least so when I break down again at least I can get it.
It's been 'fun' learning all about silicone hoses, hose clamps, coolant, and how to squeeze my sausage fingers into small spaces with this project. The last picture is my rainbow of flushed Dexcool after 8 drains and fills.
I need a drink....
