EGR delete

[amb82]

My truck had the egr delete done already when I purchased it back in febuary. My question or concern is that the egr cooler and valve is still in place. From what I undrestand from the previous owner is the EG flow is blocked off with plates to the cooler and a new uppipe was installed with no scoop. Is this EGR delete sufficient? Do I need to remove the cooler and valve? I would rather not fool with it if there is no bennifit in removing it.

A full delete would be best. The later years (late '04-'07) EGR coolers aren't the greatest and have the tendency to fail.

You mentioned the exhaust side is blocked off, if your EGR cooler were to fail, this only prevents coolant from entering the exhaust. If you want to prevent coolant from entering the intake manifold, you will need a EGR valve plug. You will replace the stock EGR valve with this plug, and take the stock EGR valve and tie it off to the side, then leave the stock valve plugged in electronically.

Here is the spool plug.

This setup is just a peace of mind if your cooler were to fail, it will help prevent coolant from reaching the cylinders that might cause hydro-lock or worst (lifting the heads).

Your sig don't say if your running some sort of gauge/monitor for ECT/EOT, you might also want to get something soon to check your delta.

Yeah I need to check my delta. Trying to convince the wife why I need a moniter. Correct if iam wrong but doesn't the lastest ford flash throw a code or something if your delta gets to high?

I believe the Ford CEL goes on when the delta is greater than 25*.

Wow. That's pretty high. Iam going to get an alignment at the dealership this week. Would they be able to check the delta?

[Lilpooh]

Yes they would be able to, but remember, you must have a warmed up motor (190ish), cruising at 55-60mph, on flat ground, for a couple of minutes, then check the delta.
