Rust in the coolant reservoir

Hey guys,

I got a coolant flush about 7 months ago, and yesterday when I went to get an oil change they told me it needed to be done again. Well, first they told me that there was oil in the coolant and that the head gasket was leaking, but then the rust settled in the bottom and they revised their diagnosis.

The reservoir bottle has a good bit of chunky rust in the bottom, but after 10 minutes of sitting it has all settled. I popped off the radiator cap and the coolant there was brown.

I dont want to spend $150 getting another flush and have this crap again six months from now. When I had my alternator replaced a couple months ago they told me that the water pump pulley had some play in it and that it may be going bad.

So my bottom line question is: Where in the cooling system can rust be introduced?

I want to say the radiator, look at the prices at your local parts store, should not be too expensive and its a pretty easy job. If i were you i would also replace the water pump.... Do you trust your skills? or are you going to take it to get done somewhere?

I could probably replace the radiator, but replacing the water pump scares me. I replaced the exhaust manifold last year, but it took me 3 entire days :P

Aren't radiators aluminium, and therefore do not rust?

That is most likely rust and scale from the entire cooling system that has collected in the overflow. Does not necessarily mean that the radiator is bad, just means the corrosion has happen between the iron block/head, heater core, radiator...

I would get another coolant flush done at a competent place and not a 15 minute oil change place...

Just to note--the cylinder head on an XJ engine is cast iron, just like the block.

I don't own an XJ any longer, but I still think they are the best of all the Jeep products ever made. My XJ was my favorite vehicle in my 50+ years of driving.
So...I stick around and give advice.

I used to work for Jiffy Lube and we did coolant flushes all the time. It basically consisted of pulling the lower radiator hose, draining, and refilling. I wouldn't let the guys there touch my Jeep with a ten foot pole.

You could do better work in your driveway than you will get at an oil change shop. Take it to a competent mechanic or do it yourself.
