98 DOHC EGR P0401 Code Fixed but Question

[chichi-kitty]

I was working on my son's car EGR checked out ok but had to clean passages on the intake side, after removing throttle body, code gone now. I'm a little concerned about the torq specs for the EGR valve. Autozone told me 20ft-lbs, seems ok for lower bolts that plug into iron pipe, but a little high for the ones that screw into the intake manifold. I have 2 manuals and neither one give specifications for DOHC engine. Ones a Haynes and one a Chilton, strangely enough they have the same text and pics. I did find torq specs for a 2.4l Duratec engine.

Was wondering what manual that covers this engine thourghly. I suspect about 10ft-lbs for upper EGR bolts, but would like further verification on this.

Thanks

The EGR valve to upper intake manifold bolt torque spec is 15-22 lb-ft. The EGR valve to exhaust manifold nuts should be tightened to 89 lb-in and then turned an additional 90º. Before tightening the bolts install everything loosely first.

A factory service manual would cover all this in great detail. The Haynes/Chilton's manuals leave a lot of stuff out. You can buy a used service manual one online (e.g. eBay).

+1 on the factory manual. You can also get a subscription to alldata for $9.99 per month if you want which has data on many more cars, it's also searchable. However 5 months of that and you've paid for a factory manual.

Egr valve "bolts" (top)= 15-22ft-lbs. Egr valve to exhaust manifold tube "nuts" (bottom)= 26-33ft-lbs. These torque specs apply to your 98tec.

Thanks won't worry about stripping upper bolt holes now. Will pick up factory manual saw one on eBay for 30

The above torque specs are out of Chilton/Haynes repair manuals. Chapter 2B- ohc eng.

Thanks Sheila feel sort of dumb now . I had on my mind that they would be at the beginning of the chapter. I didn't see the throttle body on the torque list though I tightened them to 9 ft-lbs

Haynes lists the torque specs at the beginning of ea. chapter. Chilton at the end of ea.
