My mechanic tells me I have a coolant leak in the feed off the intake, between intake and the EGR, on my 1989, V6, automatic transmission Toyota Sunrader. He describes a series of steel pipes and hoses between the intake and the EGR, and says the leak is in a steel pipe coming off the back of the intake (and underneath the intake), so closer to the intake than the EGR. He has gotten multiple pictures from the Toyota that he says are not helpful in identifying the part, and has been told those parts (the series of pipes and hoses between the intake and the EGR)) aren't manufactured any more. Does anyone know of an aftermarket company that might make it. I'm told auto dismantles don't generally like to take this part off the engine as the engine itself then becomes difficult to sell.

I have a (discontinued) Vetor Maxx sst, power inverter, 2000 watt, "VEC054D" that can power up to 17 AMPS. Looking online and in the manual I can't find a mention of a transfer switch.

I have a 1989 Sunrader that has #4, 6 volt deep cell batteries that are connected in series and parallel. My cabin mechanic says I should be able to run the air conditioner off the 12 volt batteries for maybe up to 40 minutes. I’d like to run it of the system for about 10 minutes just to cool the cabin before going to bed. I have an inverter, but am unsure if I have to plug the AC into a socket that’s connected to the 12 volt/inverter system, or if it should automatically come on when disconnected from land line 120v service. I haven’t been able to contact my cabin mechanic lately.
