Hey guys I have done some research and I have found a lot of info on how to to install the pump.but I just don't know if the car should be cold before removing the bleed nipple ..lats time I did it cooling(antifreeze) liquid came squirting out ? So how did you guys do it ? Thanks in advance

 

Well, I definitely wouldn't handle hot coolant. lol

 

Lol yeah I figured ..have you done it before , ?

 

Handled hot coolant? yes

I've also handled hot brakes. lol

 

[QUOTE=HeissRod;6057022]Handled hot coolant? yes

I've also handled hot

I ment to say have you switch your pump ?

 

Yes, I have but I don't recall how I bled it.

 

No need to bleed the system if you clamp the hoses close to the pump before you remove it. You can use anything from small C-clamps to a vice grip. I seriously advise that you let the engine cool overnight as you will be working under the car and hot coolant in your eye is not anyone's idea of fun. Very easy replacement with basic tools and should only take you 30 minutes.

 

Really bro ?What about the air inside the pump?are you saying this by experience?thanks man ..I'll be working on my car tomorrow

 

The pump sits at the lowest point of the circuit, so the main thing is avoiding all the fluid from pouring out on your driveway. Having watched more than 1 pump replacement (3) its as simple as:

• Clamp both hoses (in/out)
• Remove 2 screws that mount bracket to frame
• Loosen hose clamps
• Pull hoses off (pump falls to floor)

Install new pump

My changes have all been done on a hot engine, but my guy likes it hot!

Much easier on a lift.

 

I didn't bleed mine when I replaced it..

 

Oh yeah, this post reminded me. I used locking hose pliers as well. You don't want to use standard locking pliers as the sharp edges could cut your hose.

 

Well, yes, I did that too, but I didn't specifically bleed the system.

 

Dude how did your car run if didn't bleed the system ?

 

It's so easy but still that bleeding part gets me dude ! Lol I heard if you don't bleed it it's bad for your system ...what year is your 55 bro?

 

Don't stress about it, if you clamp the hoses it will be fine. Don't worry about the air in the new pump. Reconnect hoses to the new pump and unclamp. Leave it for a minute or 2 to let the fluid fill all the gaps and push any small pockets of air out, then start your engine.
Take your car for a drive for a few minutes to warm up sufficiently for the new pump to start circulating the coolant. When you get back from your drive find your bleed nipple - it is located near your supercharger clutch (nipple with small rubber boot and clamp) - use a plastic hose to connect to this and route the hose to your coolant reservoir. With your engine already warmed up and running it should divert coolant from the nipple to the reservoir through the plastic hose and get rid of any unwanted air bubbles. Easy.

 

Grate info bro thanks a lot ..I will jump on it tomorrow morning ..One question once I remove the nipple there's going to be coolant squirting out from there right ?It happened to me last time I was just testing it :/ ?Do I have to be quick about it or there shouldn't be no coolant squarting out ?Thank you

 

You don't need to "bleed" the system as it automatically bleeds into the fluid reservoir. Just double check your fluid level in the reservoir the next morning and top off.

See line c

 

Bro that is not how my set up looks ..my resovor is on the right side ..but I did do the bleed thanks

 

Update ----
What's going on man ..I finally replaced the pump it was so easy !!even the bleeding part I did notice a big gap of air going threw the clear hoes ..but then I let the car sit like 5 min and still saw small Lil air bubbles did you have the same problem ? Car feels faster and better response don't know if it's just me or it gave it better power

 

bro are you sure? Its supposed to be on the left side. you might have bought a messed up E55.

 

Hahaha nop it's on the right I have two other friends with e55 and it's the same :/ weird

 

Glad you were able to realize the fish hook on that one.. still the diagram provided is from the factory. Good to know you were able to regain some power!

 

Haha yeah I feels like it gain power or something just feels grate ..but I'm still concerned about the little air bubbles that still where coming out after 5 min of my car running ..

 

You should / need to bleed the stock system.

If you have an aftermarket reservoir (aka split setup), you don't need to bleed as the system automatically does it...

 

As stated by other members, you don't need to do anything to bleed the system. It's got a small bleed hose, really thin looking one going to the reservoir.
