Which Hose to Change at 100K (Coolant)

I'm planning in changing a few hoses also since I'm about to change the water pump.

I have a question about what hoses to change?

I plan on changing the following:

Part # 11531436408 BMW (OE)/CRP-Contitech - Radiator Hose; Lower to Thermostat Housing with Temperature Sensor Fitting $20.33
(#03 from realoem.com under Engine Cooling)

Part # 17127510952 BMW (OE)/CRP-Contitech - Radiator Hose; Upper Radiator to Thermostat Housing $28.09
(#01 from realoem.com under Engine Cooling)

Part # 17137787039 MTC/OES Expansion Tank/Coolant Reservoir $49.95
(#05 from realoem.com under Radiator)

Part # 11531436410 CRP-Contitech - Cooling/Coolant Hose; Water Pipe to Expansion Tank $18.43
(#05 from realoem.com under Engine Cooling)

I'm ordering these parts from autohausaz.com

My question is do I need to also order these two additional hoses?

Part # R3055-279112* or 11531705210 Heater Inlet Pipe $29.00
(#08 from realoem.com under Engine Cooling)

Part # G2021-279352 or 11537502525 Water Pipe $33.97
(#06 from realoem.com under Engine Cooling)

I would not. Doesn't look that easy to replace. Like it needs the intake manifold removed to get to it.

My opinion, the heat hoses doesn't take that much abuse(heat and pressure), unlike the upper radiator hose, so it should last pretty long.

I was thinking the same thing - I didn't really take a look at the hoses yet - but if it's not an easy 10 minute job forget about it.

When replacing the upper/lower radiator hose - does everyone get new antifreeze from the dealer. I already had my coolant flushed in 01/2007 and it's suppose to be good for 4 years. Can I just fill it with distill water or use the antifreeze that falls out if I can catch it all.

You cannot refill with distilled water and you shouldn't reuse the old coolant. Top it off with 50/50 bmw coolant and distilled water.

I have the upper and lower hoses available if you'd rather not pay full price for them. Ordered them from bavauto.com last month when I did my thermostat, water pump & belts, but decided not to replace them yet (I'm only at 58k miles). I paid $48 for both, and will sell them for $43 shipped if you (or anyone else) are interested. PM me if you want them...

I'm paying $48 for both hoses and getting free shipping since my total order is over $50.

So paying you $43 shipped and saving $5 is not worth it for me. If anyone else wants/needs it - go for it. But thanks for the offer though

Thanks for the info,

I'll pick up a gallon of BMW antifreeze either at the dealer or add it to my order ($19.95) whichever is cheaper.

Call the dealer and compare the price of the coolant.

FYI: Here's a list of all the work done on my car (Both maitenance and service warranty)

I have/had the 6yrs/100,000 miles extended maintenance service warranty and had the following things replaced while under the extended maintenance service warranty:

(I was the 2nd owner and the 1st owner bought the extended maintenance service warranty good through 100k or 6yrs - but the volkswagon dealer that I bought the car from didn't know anything about it - heck I didn't find out until I took it to a BMW dealer for my 60K inspection - checkup)

**In other words - the extended maintenance service warranty cost me $0.00**

* Engine Belts $300 03/18/06 60,086

* Rear Brakes $650 03/18/06 60,086

* Inspection II $600 03/18/06 60,086 (Price is an estimate since the invoice had no $)

* Coolant Flush $200 01/13/07 75,289

* Inspection I $300 01/13/07 75,289 (Price is an estimate since the invoice had no $)

* Front Brakes $650 05/03/07 80,778

* Brake Flush $200 07/12/07 84,441

* Inspection II $600 11/17/07 89,004 (Price is an estimate since the invoice had no $)

* Inspection I $300 05/27/08 96,381 (Price is an estimate since the invoice had no $)

* Rear Brakes $650 05/27/08 96,381

* O2 Sensor $1200 07/30/08 99,637 (Price is an estimate since the invoice had no $)

* Spark Plugs $200 07/30/08 99,637 (Price is an estimate since the invoice had no $)

Total cost (Maintenance) = $5,850.00

Total out of Pocket for me = $0.00


I also had an extended service warranty through autowarrantybroker.com and they repaired/replace the following: (Plan cost me $2,100.00 for 6yrs/100K with no deductible)

* Wheel Bearing $332 03/10/06 59,675

* 3 Window Regulator $1,010 03/10/06 59,675

* Sun Shade fix $235 03/10/06 59,675

* Passenger Power Window $450 05/03/07 80,778

* Front Control Arm Bushings $300 05/03/07 80,778

* Thermostat $285 07/12/07 84,441

* Windshield Washer Pump $155 07/12/07 84,441

* Valve Cover Gasket $350 07/12/07 84,441

* Headlight Washer Pump $170 03/07/08 93,063

* Belt Tensioner & Idle Pulley $350 03/07/08 93,063

* Replace Torque Convertor & Transmission Fluid & Filter $2,393.73 05/27/08 96,381

* A/C Belt Tensioner $195.96 05/27/08 96,381

* Oil Housing Gasket $664.13 05/27/08 96,381

* Oil Filter Housing $734.72 05/27/08 96,381

* Oil Pressure Sensor $450.00 07/30/08 99,637

Total cost (Extended Service Warranty) = $8,075.54

***Total Maintenance Cost + Total Warranty Cost = $5,850.00 + $8,075.54 = $13,925.54

My out of pocket cost = $2,100.00 (Bought the Extended Service Warranty)

$13,925.54 - $2,100.00 = $11,825.54 = Money Saved

Regarding the Heater Inlet Pipe mentioned above (Genuine BMW Engine Heater Inlet Pipe 11531705210)....mine sprang a leak....

Does anybody know if I have to remove the entire intake manifold to change?
Has anybody done it? How much work is it?

Thanks in advance to anybody who can answer this!

If you are into changing parts that don't need changing then change the lot otherwise don't change them unless they are showing signs of damage. My E36 had factory hoses and rad on it when I got rid at 250Km miles. Far as I know its still going strong. If you use the right coolant then there is no reason why hoses should perish.

That's only from the perspective of someone who would never touch their car under any circumstances. Very few of us on this forum would pay these sky high prices when our labor will save thousands in labor costs.

For example your windshield washer pump is listed at $155
Most of us know it's a twenty dollar part and a twenty min job.
So you're not in our world.

For either of the composite coolant pipes under the intake manifold, yes the intake manifold must come off. It's a ton of work.
I'd not ever consider replacing only one of these pipes. If you must go in, do both. And I'd consider the knock sensor if I were there: 13-62-7-568-422

You are very wrong....the parts do need changing.....I can see the heater pipe actually leaking coolant. The car has 197k on the clock.

As I said before "... unless they are showing signs of damage ....". You didn't read that bit?

You are correct, the part can be obtained for less money.

Ya, you're just jealous for spending $155 at your local dealer!

And it was just sarcasm. But you couldn't figure that out with the smiley's, could you, and had to make a "personal" dig?

Seriously dude, it's just a frickin windshield washer pump. How much must a "man" spend on a POS pump to be accepted in your "gazillionaire's" club? That's one thing I've noticed on this forum, there's a lot of up-tighty snobs.

Look back and you'll see I suggested the part was only $20.
