Does anybody knows the spark plug location for 2020 Chevy blazer Lt 3.6L.

Thank you...

I see you've posted this twice. Have you gone to your nearest Chevy dealer and asked this question? Maybe a quick Google? In the time it's taken you to post twice about this and wait for answers, you could've driven to a dealer's service center and had them point out the locations to you with their finger.

Under the foam rubber covers that are on top on the cylinder head. Factory plugs are iridium and good for well over 100k miles, why replace?

Well, you're right about how the service advisors respond. I've had that response also. It's unfortunate that our economy has placed us in a position where people would rather stay at home and suck on the tit of government and take free money instead of working and earning a respectable living. Many companies are suffering with fewer employees, and the result is what you experienced. Keep in mind, the tech gets paid on flag hours to work on the car. They don't get paid to do phone consultations. Every minute the tech is preoccupied with something that doesn't pay him equals money lost. If I were you, I'd drive my Blazer up to one of those dealerships and sit on their drive until someone sent a tech to visit with you. Calling on the phone will typically get you nowhere.

But, I digress...

As the previous poster above you stated, there are those foam rubber insulated caps on your valve covers. Those are there to quiet the lifter ticking. Depending on what you have, 4 cyl / 6cyl, you'll have some different steps to replace plugs. I have a 6 cyl, so it looks like I would have to take the intake cover off just to access the set of plugs closest to the front. I don't do my own servicing simply because it's so restrictive in the motor and very tight. I just have it done and the work is warranted. I've searched and can't find a schematic of the engine to see exactly where the plugs are located, but I have looked around in my motor and have a good idea. It looks to me to be a pain in the ass to replace plugs.

Good luck, and may the force be with you.
