There was a big problem with refrigerated sea containers blowing up in Vietnam some months ago due to this problem. I think it resulted in some deaths and large amounts of sea containers having to be...

I think you will find that PTFE tape exposed to refrigerant blends and polyester oil will start to leak eventually hence the loctite or other suitable thread sealant.

We use Loctite 577 here in the UK, If your Leak Lock is in blue coloured tubes i have used it as well but i prefer Loctite 577 but you need to ensure the connections are dry and clean to start with....

In that case it might be as cheap to replace the chiller if glycol is inside it now. Good luck whatever you do. You will find it a useful learning curve. I know of many techs with many years of...

You need to take a step back and think about this.
UNDER NO CIRCUMSTANCES START THIS UNIT UP WITH R410A.

At 21 years old i would be looking to replace it not change out cooler and other parts.

Your main problem is that you will have up to 50% of the oil mixed with the refrigerant, so if you only drain the oil from the condenser then you will only get a few litres of oil at most which is...

Yes you have a phase 3 pro dialog.
Which oil filter are you changing internal external or both.
If you are experiencing multiple oil filter failure problems you may need to change the oil as well....
