Engine Cleaning Tips

[Sirhan]

Hi Guys

I need to clean my engine, with my other cars it is pretty much straight forward been a toyota and hyundai.

I fear that I might break something that I should not on my S54.

I need advice on which cleaning products to use and the cleaning process please?

Thanks in advance. :thumbs:

I was told NEVER wash when hot as something may crack...? :fencelook:

I was told this is true IF you have an aluminium block?

Cast Iron blocks can be washed when hot?? :fencelook:

Probably but is it worth taking the risk :fencelook:

Also hot engine = cleaning agents drying faster surely :dunno:

Wash the engine when it is cool! And even if you just move the car from cold to a different position and switch off, the exhaust system is already been exposed to some significant heat. Safest is to do this when cold!

i want to invest in a steam cleaner for the engine, as there some places where pressure cleaners shouldnt go. :rollsmile:

The links helped! :thumbs:

Rowen, thanks for the offer bud. If I do not feel comfortable then I will pop your way.

washing any engine hot is not a good idea cast iron block or not there are components that can crack from the temperature change...

also if using a steam cleaner or pressure washer you need to be careful moisture does not get in where it should not be

 

[Philip Foglar]

Yep, I prefer to use a gentle light spray of water when rinsing off - steam cleaning as said above does pose a risk of moisture getting into places it shouldn't (steam always finds away in), and high pressure sprays to a similar extent, in some cases worse of course.
