Hello All,
Well, I've replaced all my coolant parts (some twice as I was originally unaware of the need for Motorcraft parts...lesson learned). All the hoses and housings are now Motorcraft.

My 2006 LS8 is still losing coolant over time causing it to overheat.

My first question, can this car be pressure checked like I would any normal car? I.E. take it to a shop for a pressure check, or do I need to go to my local Ford dealer, or can it be done at all? I'd like to know where the slow leak is occurring.

The one thing I have not yet replaced is the coolant reservoir. I filled the thing up and the car has sat the last couple days and it is still full. Does that tell me anything or does the car need to run to leak out of there as the coolant will be under pressure?

Also note: before it is recommended, I am aware the coolant system must be bled on this thing. I have performed that function at least a dozen times in the couple years I have owned this vehicle.

OK, so I'll go ahead and replace the reservoir, as I'm sure the one on it is the original. But first. another question. Like everything else on this car, it appears this is a somewhat complicated task. So, I want to replace with something that will last.

Have any of you tried an aluminum reservoir? Like this one here:
For Ford Thunderbird LINCOLN LS 02-05 Aluminum Coolant Reservoir Tank+Cap Silver | eBay

Thanks for your time and expertise.

I just put in an aluminum reservoir. As I have looked at comments over the years I don't believe anyone has had any complains or issues with them. Fairly straight forward install. Took about an hour or so. The trick to replacing the reservoir is to remove the bottom hose from the connection by the firewall and not at the reservoir. Then pull the tank with the bottom hose out as one unit. Install is the reverse. Will save you hours of time as the hose connection on the bottom of the tank is impossible to reach.

Where did you receive one of those ? Its probably serious aftermarket, so if possible please share the source. My car has quite low kilometers, but its still 22 years old so i am planning to change the coolant tank. Aluminium one sounds like good option :) if i can source it.

Thanks. I think I'm going to go that route. And thanks for the tip on the hose hookup.

The only thing I don't like about the aluminum degas bottles... is that there is no sight glass on them.

One could lose enough coolant from other minor leaks without knowing it.

There's a reason the OEM bottle is semi-transparent.
