My uncle 98 deville has an overheating issues. I offered him help, and I started looking for overheating threads in this forum. it was so helpful. a lot of good info.
So, I started first by checking the purge line to make sure it is ok, but it wasn't. There was no flow at all.
I tried to blew it with air pressure. but it didn't help.
the long pipe under the beauty cover is ok and the rubber tube at the ends are ok too. I think it has a plug inside the fitting of the pumphousing or somewhere deeper.
I tried a finishing nails, clothes hanger, thick wires but it didn't help too, because of that fitting has two 90-degree curves.
my questions are:
Could it be ok but there is something else responsible for water/air not coming out of the purge line?
Or is it certainly clogged?
If it deeply clogged, do I have to resemble any thing to clean? or could I do it with some special tool, and save myself removing things?
I can't imagine that you'd have to disassemble anything to clear it. An .080 diameter weed wacker line should do the job.
Yeah, I think I went too far on that.
The thing is that the fitting is so rusty inside.
a flexible electric wire went ~3" inside the fitting, and still no water/air coming out.
I would try a weed wacker line, but I don't have it and don't know where to buy it. I'll look for it.
I'm not going to disassemble any thing now. I'll just try everything I could before I do that.
