What I do is remove the lower hose from the radiator, remove the thermostat and reinstall the housing then insert a garden hose into the lower hose and force water though the entire system. I made a section of hose that fits tightly into the radiator hose then clamp with a hose clamp. By removing the thermostat you allow water to pass through the block. I also set the dash to heat to flush out heater core. When I first did this after using the Prestone Flush I was amazed at how much more stuff came out of the system.
Wondering where best to place the hose to flush that part of the engine block out.

Haha Complete Novice.
I have my Haynes manual to hand and have consulted numerous forums (such as this one) on how to conduct a thorough flush. Though I get nervous when something doesn't go to plan, or something unexpected happens. The last thing I want to do is break something and have to take it to the shop. The whole reason I am doing it myself is to save on shop labour (currently off work so plenty of free time).
The reason for the flush is that I noticed a drop in my coolant level and saw indications of a leak. As I had to drain the system anyway I wanted to give it a proper flush/chem clean and put new coolant in. Replaced the thermostat while I was at it. So the answer is I am probably paranoid because nothing was wrong with the system before I took it all apart.
Putting new coolant in now very slowly. The reason I dont think the thermostat is opening is because I can normally see the coolant flow towards the upper rad hose (through the open cap) and feel the hose itself get hot. Only hoses that are getting hot are the heater core hoses at the moment.
I have topped it up with 3 gallons and currently letting it cool to try a final fill up before putting the cap on and taking it for a test drive.
Very much appreciate your words of wisdom and patience with my posts!

Ah okay yeah it has a reservoir with a hose connected to the radiator cap.
I've done the hose squeeze after warming up, cap off, thermostat opened. However alarmed when I turned the engine off and water shot out of the radiator.
Let engine cool a bit and added more water. Warmed engine. This time thermostat didnt seem to want to open. Then water started shooting out again and I immediately shut the engine off. Seems quite hot. Steam was coming off exhaust manifold from splashes. Getting worried!

Trying to figure out how to bleed air out. Is this the bleed valve at the top? Seems too big. And not actually on top.

I read that a clever idea was to replace the plugs with radiator petcocks for easy draining next time but I will forgoe this switch as petcocks can only be tightened with a normal open headed wrench and that seems like it would be an impossible fit. Also scared three petcocks in my cooling system increased risk of one of them opening due to vibration. Socket is my only hope. So will clean the plugs as best I can and install with thread tape.
