Hi all -
I'm pretty sure the thermo or wax valve, warm-up valve or whatever it's officially called on my VG30 (1988 SE V6) is stuck or no longer functional. Truck starts fine, idles high when cold but doesn't lower once the engine is warmed up, etc. I've eliminated everything else it could be, I think. I removed the air filter housing and tried to push the little 'piston' on that warm-up valve in-and-out, but it doesn't budge. It's in the same position cold and warmed up. It sets against a little screw that's held in with a little nut. I'm talking about the valve directly on the front of the TB, up under the air filter housing. It's suppose to let the idle down once the engine is warm. Has anyone had any success in 'rebuilding' or fixing, or hell even LOCATING one of those? I plan on removing it today after work to see what's up.
Any help appreciated. I'd imagine the valve isn't the same as the one on the KA24E, I no longer have a truck with that engine so I can't compare the two.
Thanks all!
