Blockchain – Do nodes periodically check block hashes?

I understand that in Bitcoin, blocks are immutable due to the Merkle tree structure which ensures that every block contains the (Merkle root) hash of the previous block.

Thanks to the properties of cryptographic hashes, changing just one bit in the previous block creates a different hash. can be Comparing the hash of the (N-1) block with the hash contained in the next block N is used to detect tampering.

My question is: When will this test actually be performed?

Some argue that:

Yes, blocks are recalculated regularly

But I couldn’t find any source for this claim.
