2007 335i AT got the intake off and radiator fan just cleaned all 6 valves pretty dirty in there! No hiccups so far except for me breaking the nipple off the top of a radiator hose that connects to the expansion tank :/ Next im going to take off the intercooler drain coolant and oil and do the ofhg and thermostat.

Quick question about replacing thermostat ive searched but couldnt find an answer...do i take off the waterpump to reach thermo or can i just get to it no problems?

If you are doing the thermostat, you might as well just do the water pump, it is an extra three bolts.
To answer your question though, you can remove the thermostat independently of the water pump.

No pictures?!? (of the walnut blast)

Not going to do the waterpump because the PO had it replaced less than 5k ago. But strangely he didnt change thermostat and i got the code P0128. Also pics coming soon on the intake clean!

I had to remove wp to get my tstat out, not sure if it's because of my ER intercooler but I couldn't pull it over the subframe and out like the instructions said

[modern_citizen24]

Also guys when i replace my ofhg would you guys start at the 3 bolts holding it in place or start with the hoses connecting to it?

Oh, well in that case I would definitely save the money.

it was literally another 5-10 minutes. I spent MUCH longer trying to figure out how to remove it seperately, than it took to r&r wp and tstat.

[modern_citizen24]

Alright ill remove waterpump to save time. Im already neck deep with this ofhg and hopefully ill be back on the road thursday with clean valves!!!

[modern_citizen24]

So when you say remove the waterpump im going to have to replace the 3 bolts securing it. Correct?

YES

The dealership damaged my block because they tried to reuse bolts

Ive been reading up on the diy and ive read that i do not need to unbolt waterpump to get to the thermostat? My car is a 2007 335i auto tran with intercooler. Thank you

[tc535i]

So is mine. Like I said, maybe it was the upgraded intercooler but I couldnt do it.

[modern_citizen24]

Ill try it. If it wont move ill take the bolts out. Thanks for the help

Block could be damaged even with new bolts.
True, new bolts are recommended but most don't get replaced with new and most blocks in reality don't get damaged.
Basically, largely depends on how careful and skilled the tech is.

Sure, you can over torque a fresh bolt too. But they stretch the first use, so easier to snap on reuse

Is nothing but good marketing and reason to upsale, especially in the NA market.
People elsewhere have been reusing the so called "stretch" bolts long time before the online "fama" begin. Even on more important components like timing belts and brakes.
In most cases customer is only being charged but the bolt will be reused.

Just removed the ofhg! Now i have to take off the och to get to that gasket! Doin work

you're telling me that an aluminum bolt doesn't deform any differently than a steel bolt?

So you don't see any reason not to reuse torque-to-stretch head bolts?

Glad you aren't working on my car, I guess...

Yes, that makes both of us happy that I'm not working on your car. However, next time you work on these stretch aluminum bolts try to pick them up with a magnet and let us know what happens

second guessing BMW's engineering and design, to account for dropping bolts

now I've heard it all

have you ever even changed the water pump? it's right at the bottom, where the hell are you going to "drop" the bolt to... the ground??
