EGR blanking plate size

[Kdawg19]

I wonder if anyone here would happen to know the dimensions of a blanking plate for a 1997 1kz-te Colorado egr valve , I can’t seem to find them anywhere, I know that I can buy them but I’d rather make my own and am not sure the dimensions, thanks

If you get the nuts off where its going then there should be a gasket you can use as a template and the plate should only take minutes to make .

And use a 6 point ring spanner to save yourself the headache i made for myself by rounding the nuts

Thankyou

Now the hardest thing is trying to find a set of 6point ring spanner’s , can’t find them anywhere lol

Halfords brake line spanner , I can't remember the size for sure but i'm thinking my only brake spanner is 10mm one end and 12mm the other ?

So a small update , I’ve managed to get the egr valve off at the top end ( I could get a ratchet behind there ) fabricated a plate but now no matter how hard I try I cannot get the egr to go back onto the 2 studs , I’m wondering if anyone else had this and has found a solution

Did you have to move your egr cooler to get the plate in?

 

[Kdawg19]

All I did was slide the egr off of the 2 studs and grab the gasket to use as a template , ( made the plate ) then slid the gasket and the plate in place and tried to put the egr back but it just won’t line up

 

[Shayne]

Loosen it at the other end .

I'm intrigued. I've had my Colorado for 18 years now, its a 1997 3.0 Diesel and didn't realise it had something as technical as an EGR valve!!
Whats the story and should I clean it after 150k miles. Still runs and rev's no problem so should I lose any sleep over it ?

 

[Shayne]

It will run better and for longer if you clean out the gunk and blank the egr .

 

[Boner]

Does it matter what end you block?

 

[karl2000]

I believe it's better to block / restrict it where it enters the EGR cooler, not at the EGR valve end

 

[Shayne]

I don't suppose it matters much which end but 2 nuts and the whole egr is defunct and void so why wouldn't you blank it at the manifold ?

 

[Shayne]

Your in NZ , not sure if you have inspections of any kind but nobody will ever look at the manifold end so your egr will appear to be fully functional .

 

[Boner]

Fair call. It’s just that I’m going to clean the inlet manifold so will already have it disasembled.
but as you say it’s only a couple of bolts.
thanks again.

В этом что-то есть и идея отличная, поддерживаю.

Would a blocked EGR Valve cause a slow start when cold?
