    Any aluminum radiators that don't crack annually?

    Last feb 2022 I installed an Alloyworks radiator from Amazon. All aluminum with 3 rows….the core is the same thickness as the tanks. Survived one Phoenix summer so far and me driving Like ahole. And the price was less than half of OEM. Right now I think they are $215

    Shaking above 65+

    Just an fyi, bad ujoints don’t need to have play that you can feel while installed, but when you take them off you can find they bind like dried out or worn or have a “spot” with play when you rotate The caps.

    Radiator for Tahoe with K5L

    They seem to like to crack on the driver side near the upper hose. Mine is K5L and after seeing the price I just went with all aluminum. So far works great in 115 degrees. Will be able to test in mountain driving Saturday, will check how it handles full throttle up the mountains to Prescott.

    Useless Information

    I had a lean idle issue on my C5 vette for years and it drove me nuts, and yes it was adding fuel trim up to +25 then CEL if idling a lot. Turns out one day I had my ex gf watching the O2's graph going up and down and I busted out the propane torch (NOT lit) and sprayed. Second I got near the...

    Shaking above 65+

    Thats why you put the stands under the axles. Obviously you dont go nuts here and punch it and jump up and down while turning the wheel......common sense has to be applied. Like a loaded gun, just dont point it at anything while performing.

    Shaking above 65+

    Put it on jackstands, secure it and have someone go through the gears gently rasing the speed. You can then look at the driveline from underneath and look for anything out of round/vibrating/shaking, etc.

    I suspect BCM... thoughts?

    There is more to testing an alternator than just volts and amps. They test to make sure the rectifiers are not bad, or you will have AC ripple which can cause havoc with data transferred between canbus modules.

    Odd Transmission issue.

    My brothers 2012 tahoe is doing the same thing, even while I was in it with the Tech 2 . I couldnt find anything except solenoid 1 had a line that was switching between not ready or not reporting or something like that. From a stop you give it throttle and it revs a few hundred rpms then pops...

    Right bank dead

    Sounds simple. Cold engine in open loop does not use the O2 sensors yet...as soon as it warms up enough it switches to closed loop and relies on the O2 sensors for fueling and it sounds like yours is dead or the wiring is bad on that bank.

    What to Buy for a Tech 2

    What happens to the rear AC temp when this happens? Does it also go warm or does it remain cold?

    The financial benefits of maintaining our own cars

    A tip I learned from the Powerstroke.org site when trying to remove the mechanical cooling fan clutch huge spinning nut from the water pump on my 7.3…….hit the nut corner with an air chisel, works in 1 second.

That is fixed ,he still however still has the intermittent start from a light, revs...

    How many miles did your front brakes go before changing? Mine went 250K

    I bought mine in 2018-19 with 86K and dealer had just installed new pads and front rotors. ONE week later they were warped. Upgraded to Geomet Carbon rotors that I had Cryo treated with police silicone calipers and after 30K with Hawk pads and driving it like those police videos on Youtube...

    Misfire at idle, cyl #8

    Ok, missing more but mostly idle or light load. Got home and pulled plug 1 since it’s easy…….looks like legit NGK plug in good shape. Started to get worried and had a fan on #8 so I wouldn’t get burned checking it. Put my hand down there and my pinky bumped the wire and it fell off (or wasn’t...

    Misfire at idle, cyl #8

    After driving it to work 30 miles and hooking up the Tech 2, I found its only #8 cylinder so that probably rules out crappy gas. I also shut off that injector and then its a solid miss, not random 2-3 per second. Feels worse in gear at idle. Im guessing plug but will have to wait till I get...
