Re: 93 2.3 diverter valve

Wow, that's quite a melt down. I've tried to keep my truck as stock as possible. However if there are no emissions concerns, I believe several people on here have eliminated that system completely. Maybe one of them can give you the information to do that. One last thing, is the air pump pumping? I...

Re: 93 2.3 diverter valve

The part of the air switching valve that is burning up is connected directly to the air injection pipe correct? There should be a check valve there that keeps hot exhaust gas from blowing back down the hose into the switching valve. That check valve is the problem and needs to be replaced. Did the ...

Re: 93 2.3 diverter valve

On further research it is also called an air switching valve. There is also a check valve between the diverter valve and the exhaust manifold. Possibly a bad one could allow heat to travel from the exhaust to the diverter valve? I will let the husband know so he can find this check valve. Thank you...

Re: 93 2.3 diverter valve

IMG_1595.JPG Do you mean this thing? I thought mine was the only truck that still had it. Pricey little devil isn't it? All I know is it routes the air from that antipollution pump into the exhaust or diverts it out that open hole. I don't see how it could "burn up". There's no heat there...

93 2.3 diverter valve

Hi guys! We have had an issue with our Pickup burning up 2 diverter valves and not sure why. I have been unable to find anything as it doesn’t seem to find me anything when I look it up online or even in the manual. Is anyone here familiar with this? And if so any recommendations on where to start o...
