Siezed Bolt/Connector Advice

I am in the process of replacing the hose from my dryer to evaporator. The inside connection came undone no problems but the connector to the dryer is giving me fits!

The mounting brace for the dryer is not very strong so I am unable to really "get on it" when trying to loosen this. I have braced the bracket as good as I can but I still can not get the bolt to turn. I have soaked and let it sit with PB Blaster and WD40 over night. I have tried heating the bolt as well but with its precarious placement I am not able to give it too much heat bc I dont want to melt anything else.

Anyone have any suggestions to a safe way of getting this connector undone? I am more than likely going to go ahead and replace the dryer as well if that makes a difference.

Did you try putting a wrench on the dryer beside the nut you are trying to remove ?

I dont know if it was just time for it to let go or not sprayed it with liquid wrench earlier (had been use pb blaster) let it sit and just tried and it let go without a fight. I am good to go now.

Thanks!

Use a penetrant and soak it for quite a while, perhaps a week. Then use a pair of flare tool wrenches to work them loose. Don't use just one.

Not part of the in-crowd since 1952. It's BRAKES not breaks. You break a bone, use brakes to stop your car. /rant
