5.0 Heater Tube EGR Block Off Questions -or- Anyone Have One For Sale?

[shane96ranger]

This question is actually for my Mustang not my Ranger. But anyway, in the attached pic I've highlighted the outlet in the heater tube which also feeds the EGR plate with coolant. Like many people, I don't want coolant going through there, and my Explorer lower intake doesn't even have a return port in the intake anyway. I've gone through a few rubber vacuum plugs trying to cap it off, but they only last a couple months before they crack and leak. So I have two questions.

1. Does anyone have a better idea of how I can block this off?

OR

2. Does anyone have one of the pipes off of an Explorer they want to sell (the Explorer has the return line in pipe instead of the intake manifold)?

I asked over at www.allfordmustangs.com and there's a member over there that suggested I weld it shut, so I might do that. I've noticed the guys over here are TRS are a bit more inventive. I'd rather have something better to block it, or a tube out of an Explorer.

Before I realized the pipe was going to point directly at the firewall I was going to cut it off and braze it shut.

So you did EFI on yours? I was thinking you did a carb for some reason. At the moment I have a U shaped hose connecting the two pipes together because I need a new heater core.

Mine is carb, but the engine (a '87) was originally fuel injected and had one pipe kind of like that with the little barb originally.

Well, I just looked at three Explorers in the garage and the all have a tube barb in each line. Lines from there go to the bottom of top intake, drivers side. Weld or braze starting to sound good. Maybe you could screw in a bolt close to the size and seal weld around it?

Dave, do they two or just one barb?

Thought someone might ask! Went out and grabed a picture of one, they are all the same. This happened to be the one that shows it best. Oh, I did visit you over at AFM. I'd swear brain dead is setting in on some of them.

That is EXACTLY what I need. What's it doing there? Is it for sale?

 

[Mac]

It's on a spare Explorer motor I bought for the front brackets and intake. I'll send you a PM.

Thank you Dave!!

If you are eliminating the EGR function, why not just replace the EGR Block with a solid block and get rid of that tube ?
Run heater hose towards the passenger side of the engine and then to the firewall.

That is what I ended up with on my ’88/5.0 setup.
it was a while back and I an’t tell you replacement numbers for the fittings but it can be done.

I know the bypass plate you're talking about. It's just a plate with a mount for the throttle cable, right? I'm actually not eliminating EGR function, I have to have EGR to pass emissions in Utah. My EGR does function fully, I'm just eliminating the coolant that goes through the plate. I've had it leak antifreeze into the motor before from the plate. It was a stupid idea in the first place IMHO.

Also, I have to have that tube, or at least a portion of it because that is where the ECT sensor resides. I wish it didn't, or I would have ran hose the whole way like my 85 GT was.

If you eliminate the coolant how will it cool down, it does get hot recirculation exhaust gas.

The ECT Sensor is the one at the base of the tube, it has been a while since I did my 5.0 swap but I think I used two fittings, a “Tee” and a “45 Angle with a hose connecting end” mated them to the manifold and each other and it worked out OK.

Let us know how this works out.

 

[shane96ranger]

For conversation purposes, let's just say I decide to hook the coolant line back up one day. I still would need an Explorer tube to do so because I have no return line whatsoever at the moment. So putting an Explorer tube on is a necessity for me either way, unless I were to pull the manifold and put a return line fitting in it.

If you eliminate the coolant how will it cool down, it does get hot recirculation exhaust gas.

I understand your point here, this seems rather logical. I have had it bypassed for years with my factory manifold with no ill effects. I've also had several friends with Mustangs do it also with no issues. So I dunno.

I'd be interested in pics of this if you have any.

I was looking at a 5.0L ho from a '93 bird that a friend is storing in my garage, the coolant tubes on that do not have the outlets either. I am sure there are more. Or get a small piece of pipe to screw into the intake, with a T, one side for ECT, other side for a barb and just run 5/8" heater hose. Doesn't sound like welding is something you want to do, I think you would have done that by now.
