Prologue (continued):
Thankful we had finally caught a break, we decided to sleep in until almost 6am! Woo hoo!
Back at the truck, things were looking a bit "frozen":
What you cant see is that when I fired the truck up, the cold idle shot up to nearly 3000rpms!
I wasn't worried about it at first, as I figured it must have just been THAT cold, but when the cold idle stopped then the normal idle was bouncing rhythmically between 500 and 1500rpms. It was a bit embarrassing since the truck is so loud and we're still in the hotel parking lot. We decide to pull out to the street and to continue de-icing the windows somewhere where we wouldn't be so bothersome.
We're driving through town a bit and pointed towards the highway, and I notice that the temperature gauge is starting to climb... How in the heck can I be overheating in this weather????!!!
We pull over to investigate.
I had my water pump changed in Africa about a month ago now, but I'm wondering if they didn't top up my coolant all the way when they were done... or do I maybe have a leak somewhere? It's the only thing I can think of. I carefully grab the radiator cap and try to twist it off.
it doesn't move...
Now why wouldn't my radiator cap.... oh my god. It's frozen. This whole thing is frozen!!!! We gotta get home by the evening tonight or my family wont make their flights tomorrow, and the entire cooling system of my truck has completely frozen over! What the heck are we going to do?? God, I hope nothing split!
(note: When the water pump was changed, I did ask for a 50/50 mix of coolant to be added. Unsure of what the freezing point of the stuff I got was yet, as I have yet to test the antifreeze)
On our drive through town Mrs. Hungary and I noticed a car repair garage. We walked there thinking they might have a torch or something we could use, but they were closed.
Mrs. Hungary thought she saw a hardware store a little further on, so we went there instead.
Success!
I get to work on the radiator with the torch. That can of coke you see there on the header was supposed to be my morning coffee but it froze over too. It's nearly thawed by the time I took this photo. My goal here is two things:
1) close the hood and use the heat from the engine bay to melt as much as it can. When the coolant temperature sufficiently drops, we can start the engine again and repeat.
2) use the torch to heat the bottom of the radiator from underneath. My main focus point is trying to make a fluid path from the inlet of the radiator to the outlet back to the engine. If I can do that then we can start moving (I do hate this torch though, it's crap)
While all that was going on, Mrs. Hungary found a convenience store nearby and bought us both coffee and breakfast
(oof. Zip ties everywhere, trash, charging cables.... There is a lot going on in that last picture)
Eventually we get things thawed and running normal. We decide we're going to err on the side of safety and block off part of the radiator with cardboard. Not sure if it's needed, but we figure stopping 60mph sub-zero temps from potentially freezing things back over would be a good idea.
After all of that, we're only about 3-hours behind schedule. Not bad, but things in the truck just are NOT warming back up the way they should be. Our toes are freezing, and it's getting tougher and tougher to keep moving them to stay warm. We stop once for fuel and a warm-up but things quickly go back to frozen once we're on the road:
It takes me a while (sorry, frozen brain) but eventually I stick my hand down by the floor vent and notice that the air coming out is ICE COLD.
Heater core is frozen solid still... And since I have the switches set to "fresh air", it's probably going to stay that way. Just in case it helps I throw the lever to "recirculate" and by the time we're 4-hours from home things thaw and we have heat again. No more stops needed.
The truck is home now, and I haven't even been able to empty it of trash from the last run. I did start a list of needed repairs, but it's the holiday season so I probably wont get to any of it until after the New Year. Next run is in April though. She'll be ready before then. The beneficiary will be a prenatal center in Dnipro. Stay tuned for more on that one
Good times
