I think you might need to go ahead and replace the hose itself if there does happen to be a current leak. Yours has already been tampered with because the factory clamp has been replaced. Problem is, that only masks another problem that will not go away - the hose is actually aging and the fluid is leaking out via osmosis and a new clamp is not going to help. If you decide not to replace the hose at this time, then you can just snip off about 3/4"-1" of tubing and reattach.Hi Michel,
I had not noticed, but, I see what you mean now.
My power steering is leaking from the bottom of the reservoir; yours seemed to have leaked from the outlet of the power steering pump. I'll check that spot later today. (I wonder if Dexron VI leaking all day onto an alternator shortens its life.)
Anyway, the suggestion to use solid clamps is a good one; the problem will be obtaining them. I'll check later on today when the parts stores open.
Actually, ummmm... er.... that's YOUR power steering pump, not mine. At least I think it's yours. I got the picture from here.Yours has already been tampered with because the factory clamp has been replaced
Funny, doh...I did not realize it was a blown up version of my pic. The link I supplied in an earlier post was from AutohausAZ. This is where I ordered all of my clamps from. I ended up ordering almost every size they offer in quantities of 10.Actually, ummmm... er.... that's YOUR power steering pump, not mine. At least I think it's yours. I got the picture from here.
By way of contrast, here's a picture I just took of mine.
Notice the factory clamp; but also notice all the dripping red stuff (mainly from my removal and bad hanging of the power steering fluid reservoir which I just realized I should have loosely placed back on the bracket once I removed the Bosch 120 alternator).
It's still unknown to me where we're supposed to get these clamps (and perhaps the crimping tool)???
Turns out, the "trick" was, explained to me in another thread, one must stick a spare dowel or allen wrench into the stress-relief tabs on the mechanical tensioners. Only then is the harder-of-the-two 13mm bolts accessible to remove the mechanical tensioners.bluebee said:There MUST be a trick to getting access to that second 13mm bolt on each mechanical tensioner.
I think this is for the angel eye. I see I broke some plastic around the edges. It now doesn't want to stay in when I try to clip it back.BTW, while I was putting clockwise pressure on the upper tensioner, my arm broke something in the headlight (see photo below). Also I heard a tiny crack in the vicinity of the upper radiator hose.
I didn't realize this bulb tray was a separate part from the headlight. I'll worry about that halo light later. Thanks for your offer.I replaced them with the LED type.
I removed the fan but not the fan shroud.Did you remove the fan shroud and fan before trying to remove the tensioners and belt?
See above in RED.I removed the fan but not the fan shroud.
My problem with the cooling system is I don't know what parts to get. If I did know that, I would have ordered them along with the belt-drive parts. (I opened a thread to rectify that for me, and for others in a similar situation).
Since it took me more than a dozen hours to get this far (of course, I'm writing and snapping pictures and confused all the time - and watering my plants whenever the frustration level overwhelms me) ... I wonder what ELSE I should do while I can.
I see the DIYs on the ICV (cn90) and CCV (Fudman) but I'm very confused WHERE they are in my car as things are different.
My main confusion now lays with the following (probably dumb) questions:
Q1: How do you safely remove the pin from a tensioner off the car?
I would use a set of pliers, and slowly remove the pin.
Q2: How do I know if I need the oil filter housing (OFH) gasket?
Is you oil filter housing leaking?
If not, leave it alone!
Q3: Where is my crankcase ventilation valve (CCV) & can I clean it now?
It's up to you, if you want to tackle the CCV now.
Judging from your limited DIY experience, I would focus on ONE goal, then later do another.
Q4: Where is my idle control valve (ICV) & can I clean it now?
Q5: How can I test if the power steering pump (PSP) is causing my squeal?
Replace the tensioners first.
Q6: What ELSE should I be doing while I'm waiting for parts to arrive?
Drinking a beer!
Thanks Jasaon. These questions may be many, but, it's worth helping me because I summarize, photograph, detail, analyze, annotate, cross reference, etc. for all of us in return.See above in RED.
Cam's detailed cooling-system-overhaul is for 1997-1998; airos' less detailed single post is for the right year (1999-2003). Pelican's decent writeup is for the 3-series; and the Beisan writeup is the closest but only covers the fan shroud and fan removal. AFAIK, there is no detailed step-by-step (which is what I need) for the 2002 525i cooling system overhaul.If you plan on replacing all of the cooling parts, then use Cn90's write-up
Don't complicate things ... drink a beer
