I am not sure they are the same, but IMO they might be better, as they appear to be plug and play for the Volvo 850. Just cover those wires with some automotive insulation.

I watched a video on the Spyder and they looked like they required rewiring.

Tempting.

I live in a ice cold state, it's likely condensation in the fuel system. Next time try a bottle of HEET. I have been using this inexpensive product for 30 years with great success.

Also keep the fuel tank full in the winter to reduce condensation. Especially when it gets below 25 F.

In my experience, the heater hoses will last forever as long as you don't touch them. :lol: Inspect the hoses. If there are no bulges, cracking, or signs of seeping, then they are probably serviceable for a while longer ~200k. They are all easy to replace baring the coolant supply line that runs to...

In one of his videos, Robert DIY says you should replace all coolant hoses every 15 years or 150,000 miles to prevent catastrophic over heating. That's good enough for me.
