Coolant help

Hey everyone ! New member, any help would b greatly appreciated. I don't have a manual yet & my 2006 Lr3 hse, V8 is giving me problems with the coolant. I started having problems one day i was driving thru town (20 mph) & i heard a bubbling noise then saw white smoke billow out from under the hood on the drivers side. I immediately pulled over & had it towed home. When this happened i glanced at the temp & it went from halfway all the way down 2 the blue line. so i got a ride 2 the Auto zone looking 4 some coolant & The men said I HAD 2 get the zerex, yellow-clear coolant due 2 the fact they won't b carrying my old coolant (orange-pink Peak) is Zerex ok 2 use for my Lr3 ?? I did a coolant flush, & ever since whenever I drive about 5 miles (under 35 mph thru town) the coolant starts bubbling (boiling??) Out of the reservoir cap. The temp never went above half way ( which I've read doesn't really mean it isn't over heating b cuz the gauge is crappy. & I don't have the tool they suggested getting 2 tell an accurate temp) I'm in the boonies & not near a dealership, so I've been going 2 a local mechanic. So far we replaced the coolant reservoir, the cap twice ( the 1st he ordered was a euro spare & I asked him 2 get a genuine cap), the Thermostat, the water pump, the T bleeder valve. & it's still boiling- bubbling out. At this point I'm ready 2 tear out my hair in frustration. We did the compression test twice 2 c if any hoses r leaky, that was fine. We did a combustion test twice 2 c if the head gasket is cracked & that didn't change color. Anyone out there have any suggestions ?

Is the tank cap tightened to maximum and was tye system filled and bled by the book?..it's important to follow the exact procedure especially for bleeding or the coolant flow can be affected by an air lock : https://docdro.id/5q3gquv

Bleed properly - that’s a common problem. Sounds like you covered everything else that might cause the symptoms you describe.
