CX-9 Engine Replacement Compatibility

[vadimkru]

Hello,

I have 2018 CX-9 that has the cracked head with coolant leak (confirmed by dealer). The warranty work was denied due to car having salvaged title.

I’m looking to buy a replacement engine from 2023 CX-9. Do you know if it is a direct replacement?

I know that I have to replace with an engine that is at least 2020+ that has the fixed head design.

Technically yes but you'll want the 2023 ECU as well. What I don't know is, does that affect any other system.

So why would you replace the whole engine? Just buy the cylinder head. I understand you are not in the USA, but even with shipping and customs fees, it will still be cheaper. I contacted Mazda USA, and they provided me with the part number for the cylinder head. I specifically asked for the updated one, from after 2021. Here is the part number for the updated cylinder head.Look it up on American websites; some of them have promotions now where you can buy it for $650.

That is certainly preferred to an engine swap which is a huge job--but I would recommend the complete assembly rather than a bare head.

Это, конечно, предпочтительнее замены двигателя, которая требует огромных усилий, но я бы рекомендовал полную сборку, а не голую головку.

«Ну, это зависит от того, в какой стране вы это делаете. В моей стране, например, замена головки блока цилиндров стоит около 500 долларов. Автор может быть не в США.
Целый двигатель может обойтись в очень большую сумму
С уважением.

"Well, it depends on which country you do it in. In my country, for example, replacing a cylinder head costs about $500. The author may not be in the USA. Respectfully.

Around here (Midwest USA) you will spend a lot more than $500 to replace a cylinder head.

But what I'm referring to is there are two part numbers--one for the head only and one with the valves etc installed. It saves on labor and eliminates errors. I don't have it but I believe @yrwei52 does.
