I'm glad I bought all new pulleys. The a/c and idler were starting to go. Also, got a killer deal on a new ina hydraulic tensioner from a guy on eBay, so picked that up.

I probably am doing more than I really should. Bought too many parts to list but hell, this is fun! All new nuts/bolts for everything. I also replaced the rad mounting parts.

Get a longish socket extension and place one end on the bottom of the ET. Push up on the other end with your floor jack. Pop. Out comes the ET.

My Ride: 01 325i
The other day I noticed that my temp gauge seems to be running just slightly past the middle on my 01 325i.
It is not overheating, just a bit past where it has normally been even thought it is cold like mid 30s. Has this happened to anyone else?
I wonder if I should change my thermostat (?).
I'm a little hyper sensitive to my car overheating. I bought her as a fixer last year with a known blown head gasket. I studied all the posts here, bought a gasket set, rented the VANOS tools from Dr. Vanos, and replaced it.
I did have a machine shop pressure test and re surface the head too. I also replaced the electric fan that had failed and it has run like a champ ever since for over 9k miles.

Any incite would be much appreciated...

Next time the gauge goes past middle, read the temps via OBC. Report back. They should not go above 99c. If you do, you have a problem.

Yes, awesome idea I agree! My cheap ODB scanner doesn't give me temp, but I'll find one that can...

So 99C is the middle of the gauge I assume (?)

the middle of the gauge is a wide range. It's something like 80C to 105C. You should be at 95c at operating temperature.

You've ignored Mango. He said OBC.
Your dash gauge is not accurate; if it is going slightly high, there is a good possibility that you're headed for the danger zone already. Ignore the dash gauge.
Use your hidden OBC functions to accurately read the engine temperature as you drive around.
May be your thermostat or pump. What is the condition of your whole cooling system. Ever replace the rad?
Hope nothing broke off and stuck somewhere in your engine from last time it overheated.
Sure your electric fan is working properly?
Your car heating up even when cruising as opposed to sitting at a stop?

Your skill set is higher than most on this forum, you just need some pointers about this e46 specifically.

Print out and keep the function list in your glove box.

this. read view the on board computer.

hold left gauge stick down until it says test. then immediately tap it til it reads "19", let go then immediately tap it until it reads "7." Your temp will then display.

Your gauge will read in the middle at 99c, but 99c is the upper limit of the acceptable temp range of your cooling system under normal driving conditions--even when driving the snot out of it. Mine reads between 93-95 and never goes higher. If it hovers around 100-105c and doesn't really go higher, then usually you have an air pocket. If it goes higher, you usually have a bigger problem. GL!

My Ride: 2003 325i Sedan E46
I have a 2003 E46 325i w/ Automatic transmission. The radiator part # listed on the first post is 17119071519.

When I search under BMA parts for my car, I see part # 115 06049 036 which is for a Behr radiator for my car.
However when I search REALOEM, it doesn't recognize the BMA part #. What am I missing?

I found this thread with no real explanation of why these 2 part #'s are for Behr radiator for my car and am totally confused.

Link to same question but no answer

If I buy the one from BMA Parts, it is $122 after using 5% coupon SPEC30. Clearly I don't want to buy the wrong part.

Any help would be appreciated. Thanks in advance.

Should list last seven VIN digits if you want help with realoem.com.

RMeuropean.com recognizes the 1st post #
http://www.rmeuropean.com/search.asp...=115+06049+036

Maybe enter part # in www.furiousmethod.com to see what you get.

EDIT: looks like BMA is listing their own internal part #'s, not the BMW #'s.

My serial # is NJ39067 and it doesn't mention part # 11506049036 but I can't believe that everybody is buying the wrong part from BMAParts....

When I search part # 17119071519 on BMAparts.com, it says "Product Results for: 17119071519 ( 3 matches ). Click here to see if we have alternate items available"

Totally confused.

Do not buy that. Aluminum is not needed here. Buy a Wahler brand Tstat. Stay off eBay!

Thanks, appreciated. So it will be either Wahler or Zionsvillatr plate kit as I need this car to run a bit cooler.

This offering sets off all my Cheap Chinese Crap alarms. Got to develop a nose for this and maintain some discipline.

Wahler.

Why do you need it cooler than it's normal 95C? Are you boosting?

No, it's just that in summer here it gets almost 45-50 deg C so looking for something to help keep it cooler. I believe a mechanical thermostat at 80 is better so the avatar car temp ranges up to max 90 degrees. Regardless of the previous threads, I still believe a bit cooler is better especially that my car is still stock end to end and imported with only 42k Km, so why to induce heat buildup so early.

I don't think you have anything to worry about. The engine is designed to run at 95C and it will do so in that weather. Run premium gas and there will be no problems in that heat. That'll keep it from having to adjust timing to avoid detonation due to overly warm fuel/air mixture.
