No Mike I did not freeze the machine. I said that the water hose going from the transfer pump on the water tank was freezing because its near the door, No part on the machine froze.
Bob and others asked lots of good questions like did you burp the HX and or the truck, did they check this, did they check that. The answer is no. Now i want to again say this very gently so Mike doesn't accuse me of throwing an industry legend under the bus. I will only state the exact facts. After 3 phone calls with service techs at sapphire and no results I was told to take it to Chris at the cleaners depot. he is the best and will get it straightened out, OK I drive 6 hours round trip. Now I am no mechanic so I would have no idea what to look for but Bob and other have lots of good questions on where to start and what things should be checked. I would think that Sapphire would have had Chris check all of these basic things out. Like Bob said how about burping it, how about running the system the way the manual says to run it and see what it's doing, how about putting a gauge on the wand to see what it's getting for temps, lets check the water temp coming from the radiator. Is the van temp where it should be, what is the temp of the water from the pre heater? There were several more questions people asked me about the system and if we checked this and that. The answer is no. They did not check any of those things. again Mike I am not putting down an industry giant in the TM business. Plain and sample he did not check any of those things. He immediately determined that the water going into the blower HX was cooling off right away because the blower is not getting hot enough to heat the water to correct temps. He showed me how to get the blower hot and was able to reach the desired temps. Like I said I am no mechanic so I will not judge the actions he took. I feel I gave Sapphire the chance to fix it and it was glossed over. Am I the only one that feels more should have been checked?
David....don drive all them miles before you burp it....get it as hot as it will go...
reach in and open the petcock on the HX......slowly.....i betcha you got some air in there..let the air hiss out till it comes out anti-freeze...then turn it back off...easy peesy!
i'd do mine maybe once a week....jus so i'd know there wasn't a bubble in there..
even a small bubble of air will impede the flow of coolant!
