I have been using Nissan sunny and I want to buy Toyota corolla but im little more afraid of the engine block is aluminum

Simple , if you are concerned then don’t buy it .

Maybe someone else can weigh in about assessing concerns about aluminum engines. I know we’ve had discussions about this in the past.

Aluminum engine blocks were problematic when they first appeared (like just about any new technology) but they have been in use for many decades now and are pretty much ubiquitous…nothing to fear…

Yeah, back in 1962 my junior high shop teacher told us about wear problems in an aluminum block engine, fairly new on the general market. Some aluminum block engines - Renault? - had cast iron sleeves for the pistons. But we don’t hear about those problems any more, in many years, it seems.

Actually an aluminum head AND block helps eliminate head gasket problems seen with aluminum heads on a cast iron block.

I’m not aware of any concerns, other than the fact that you really need to address any overheating issues immediately.

Now that you mention that, my shop teacher may have been talking about problems with aluminum heads on cast iron engines… been a while. He may have been talking about a particular American carmaker that put that combination on a popular car - so the numbers of problems were noteworthy.

The majority of car engines are all aluminum (aluminum heads and block), it’s a very common thing these days. The Corolla has had aluminum blocks and heads for the gas/petrol models for the past twenty years.

Should I be wary of an aluminum engine block?

Aluminium blocks have been sorted for years. The issues people have with modern engines aren’t usually because of the block.
