My 2013 Ram 1500, break vaccume pump. 5.7 location!!

[TigreST]

Cursory glance under the hood and undersides of my 2018 5.7 Sport 4x4 chassis shows no sign of that pump you have pictured.

My 2013 1500 Sport 5.7L doesn’t have 1 either. It sounded like the ecodiesel has it though based on your previous post. So, if you’re low on vacuum you might want to start checking the engine for vacuum leaks or do a compression test on the cylinders to make sure everything is good in there if you don’t see any other issues in the brake system.

Your 2013 truck does not have a electric vacuum pump. The 5th gen 2019 5.7 trucks do but not the 4th gen 5.7.Only the 3.6/3.0 fourth gen has one which is mounted to the front of the engine. You’re searching for something that doesn’t exist on your truck. I can guarantee you this, as an FCA tech for the past 10+ years.

If you have low manifold vacuum and all the hoses are good then it’s an engine issue. If it has an aftermarket cam this can lower vacuum as well.

It Does have the pump. I got the pump ordered from mopar with my Trucks vin number and motor number. Also if you actually look at the page i posted from the shop maunal it says right there 2013 and later 1500 models. Mopar uses vin number to verify fitment.. So who ever said it doesn't have one is wrong. Also my AC does have is lower funtion. You are right about it controling other funtions as well. Again.. I know this is the issue and it is for my truck. Just trying to see where it is. Please look threw the intire thread if your goong to comment because most of what people are saying i have alredy talked about or shown.. Thanks

I read through the entire thread. I saw your picture of the service manual, which that only applies to the 3.6/3.0. On the 3.6 the pump is located on the front of the engine underneath the air intake assembly which is what the manual is referring to.

Whoever sold you it didn’t do their job. I can look up parts through FCA and on your truck a vacuum pump is only available for the 3.6. It does not apply and is grayed out on the 5.7.

Look at your brake booster. It only has 1 hose going to it, which goes to the manifold port. If you had a vacuum pump the hose would have another port on it, that comes from the vacuum pump. If it had the pump all you would do is follow the hose.

Your HVAC system is completely electronic. The only thing the vacuum pump does on equipped trucks is keep proper vacuum present in the booster during high engine RPM which creates little vacuum. Due to the engine/variable cam timing of the 3.6 the pump is required.

Grab a scan tool and you’ll see you have no data for a vacuum pump like the 3.6 would.

Your truck does not have it. You can gut your truck all you want but you won’t find it.

Not to stir the pot, but.. My admitted "random" searches in the part system under "vacuum pump" did produce results that had 5.7 gas machines as users. Again, can't provide specific's sorry.

Weird placement. I had a 88 Ford Ranger with Fuel injection. During my resto I noted that the injection pump was located on the frame rail below the drivers door sill, of all places. The mounting bracket was just a mess as it caught all the road grime and salt spray. One of those hard to see things unless you had it tore down to the frame/cab off condition.

Hemi J...if it's part matched to your VIN...then I guess we keep looking. I did notice that on the driver side..again below the door, the frame and some stuff is sort a boxed in...maybe only ABS brake module stuff at a guess. For sure..if I have one(?) it surely don't jump out at you, crafty bastids!

This guy is an FCA tech for 10+ years and is trying to help you. i get your friend is a 12+ year mechanic, but for FCA? You message back hes wrong? Not tryin to be abrasive here, but could you or someone have possibly typo'd ur vin# (you or the place you ordered from,?) when you put it in for the part? Or, are you the original owner? Could an engine swap have happened possibly?
I get your frustrated, but you came here for info and opinions, dont be a ****

If you see my post above #18, it appears you don't have a vacuum pump with the 5.7. that's coming from two Ram/Dodge service techs(Tach_tech and my buddy)... vs the rest of us shade tree/armchair mechanics...lol

 

[muddy12]

Is it possible that you are confusing the evap leak detection pump, for a vacuum pump?

Ill have the invoce with my vin on it so again thoes techs are wrong. The shop manual i puled that from is for the 5.7ltr... Im just going to find it my self i supose and show you guys when i do. Because when people havent hear of it or seen it before they assume its wrong. I know what im doing. Was just looking for advice on location... Sorry no one could help, thanks for all your guys responces any ways.

So all the factory parts information and factory service manual is wrong? You some how have a 1 of 1 5.7 truck that came with a vacuum pump?

You have zero proof that your truck has it. How do you think the vacuum pump is going to supply vacuum to the booster when there’s only one hose going to it from the intake manifold. You already replaced that hose and it only goes from the manifold to the booster. There’s only one port on the booster.

Are you sure your booster doesn’t have an internal leak? Do you know how to test the booster?

Have fun tearing your truck apart for nothing.

Follow those vacuum lines. If there is a vacuum pump it’s at the end of those hoses. If you find one share with everyone else please that way if there are random trucks with vacuum pumps we shall find out

 

[Hemi J]

Zero proof meaing the one that has it at the junk yard think im going to tear apart (not my truck) you mean Dodge parts internationally who have produced 1000s of 5.7lts with it. Or you just mean you want to be right when your wrong. Im confused... Lmao. Ill post like i said when i do later this week. Then you will have your proof and show everyone else that may need it too. To help them and not talk ****. Lol

Good luck lol. I tried to help you and so did others here. You were the one who automatically dismissed people’s advice because it went against what you wanted to hear.

You’re somehow convinced that is has something it doesn’t. Show me the vacuum line on your truck. It’s pretty simple. Explain to me how the vacuum pump is going to supply the booster when there’s only one hose to the booster???

 

[William Hastings]

Hahaha arguing with an experienced FCA technician, yet you can't spell vacuum, or most other **** in your replies. Again, possibly, how many owners had this truck before you, maybe your vin doesnt match up and changes were made, hell maybe its a chop shop truck, **** happens

 

[Hemi J]

There are more than one. The line you saw was the manifold vaccume directly to the check valve then to the booster. There are also vaccume lines that go to back behind the motor that come off of the manifold as well that i have to investigate. Im not dismissing anything i just know what i have done my self and the documents, parts people, dealers ect that i have dealt with and already talked to about it. Like i said ill find it. Im guessing its mounted to the frame or behind the motor. Im going to mopar Direct tomorrow before the junk yard. Talked to a guy that said he could show me where its at.

This is right from the factory service manual for a 2013 1500.

The only factory vacuum lines are manifold to brake booster, manifold to purge solenoid and manifold to PCV valve.

Maybe someone did a engine swap on your truck and messed with a bunch of crap.

 

[Hemi J]

Never know. Ill find out by this weekend. There is a matched plug on the back top of the motor that the pump plugs into (and runs the pump correctly) and drops down behind the motor as well as the line going to it from the valve. I will look more tomorrow.
