I have read multiple threads that all say the vcmuzzler by verbatim is designed for a variety of differences in climate. The key is to use the different resistors to get the temp below 167. I have my DIY version that I started by using the 82 ohm resistor. The temp reported around 170, so I switched to the 100 ohm. This time, the temp is right at 167, but the vcm is still coming on. I am guessing that the temp has to be below 167 for vcm to be disabled and sitting at 167 is not cutting it.
I know that logically, the next step would be to try the 120 ohm resistor. However, since I bought the van, I have had the smell and "taste" of coolant in my nose and mouth after the van has been out for any significant length of drive. I first did a block test to see if it was the head gasket, but it came back as a pass. I had observed that the radiator level was low, but the overflow tank was full. The other day, I noticed steam coming from the radiator cap. I suspect that the cap is preventing the overflow from being drawn into the radiator. I plan on replacing the cap very soon.
My ultimate question, I am guessing that I know that answer to but would prefer asking here, is does the vcm system only fully get muzzled if the coolant system is working perfectly? I would rather spend the energy and time with getting the cooling system working than fight with the muzzler if that is the true issue. Is it common to have to run a high resistor in winter? I know that some people have said they run high in summer, which makes sense. I am just stumped with this muzzle job. Any helpful advice is greatly appreciated.
