Worm clamps suck!!!

Yes they do, but it was all I could get in there without removing the entire radiator.

Even with the tool, i hate spring clamps. Generally i replace spring clamps with worm clamps, if i have to touch it, it's getting changed.

the trick is don't tighten then with a screw driver. snug them with a 5/16th on a ratchet and never had a issue.


I have had to follow behind a lot that guys left loose thou.

I tend to just reuse whatever is there if in good shape. I do remember that lower passengers side being a hassle, but remember exactly what I used, but I got it back on.

Thats what I remember too, the clamps on radiator were the hardest part of installing a new radiator! Removed and installed with hoses attached. Clamps had to be rotated just right to maybe reach in there with regular pliers which require a good amount of force, which would slip off the spring clamp easily.

It was about 110* when I was doing the work and after about 45 minutes of fighting that spring clamp I gave up and used a worm clamp.
I wasn't about to yank the radiator in that heat.

went ahead and replaced the bank 2 sensor 1 02 sensor, I don't think it was bad but it was the only one with about 70k on it.
replaced the bank 1 almost a month ago and oddly enough the 02 sensor's have not set yet, which is weird normally I think they take about 3 days.
I have not driven it a lot maybe a little over a 100 miles since the 29th of last month

Fingers crossed that you have taken care of the issue.
Calif is talking about setting up roadside sensors that will know if your car has a check engine light and it will send you a citation or suspend your registration.
These same sensors will read exhaust gasses and take pictures of your plate to go after you.

BS like that along with the proposed mileage tax are just some of the many reasons I moved out of California.

i don't know about them knowing if you have a cel on or not but that alone is not a offense, it does prevent you from updating your registration once every 2 years and if you can show you spent at least $500 attempting to repair it then you get a 1 time pass. so in theory you could drive around with a cel for 4 years with no recourse
they have setup said sensors in so-cal from what I have read and if you happened to get flagged they would have you get a smog test, but from I have read those so far have only been in a testing phase.
occasionally around here they will setup a mobile roadside test, however it is completely voluntary and they only do it to show statewide compliance
the state is overbudget big time they do not have the resources to put systems like that in place at least not at this time.
If you pass by a cop and your blowing billows of smoke then ya you might get pulled over and made to go get a smog test.

and any mileage tax would be on EV's not everyone and would be attached to your annual registration.
