Ongoing overheating

Your symptoms sound like a possible head gasket/cracked head issue. Combustion gases leaking into the cooling system could be overpressuring it and causing leaks at the weakest points. A “block tester” kit from Amazon will tell you if you have that problem.

Thought I would have my problem solved but turns out not :/ I have an Acura tsx 2005 Amt with navi Approximately 150,000 miles It’s my daily and I’ve done some work on it I’ve had an overheating issue a couple months I got it a year or 2 ago!!! At that time all I did was change the temperature sensors on both engine and radiator which somewhat solved my problem, as it would sometimes overheat and sometimes it wouldn’t Fast forward to a month ago I decided to get a new waterpump, thermostat, and lastly a radiator Obviously when installed I bleed the radiator and it worked for a couple days till it would slowly rise again What I noticed was that coolant would come out the reservoir which I then got a new radiator cap When I did it somewhat helped But! It still kept overheating So I got a new reservoir, I got it because the threads on the reservoir cap were stripped and wouldn’t shut close which I thought was the problem So like before it also helped But not fully at this time I noticed coolant appearing from the top left corner of my radiator, a brand new radiator!!!! So I rented out a pressure test kit to get the best of the benefit It definitely was leaking and a hose that lead to the heater core behind the engine was leaking a bit too!! I tightened the clamp on it and it stopped it from leaking As for the radiator I got a new one as I thought it was faulty and it was under warranty So just this week I installed a new radiator And sadly once again coolant is coming up from the radiator like it did before I’m not sure if there’s to much pressure in the system to cause this, or what makes the radiator leak out like this It literally was new and it’s a denso brand One thing to add is that whenever I would check the coolant in the radiator air/pressure would go to the reservoir tank and make whatever coolant was in there to spill out And whenever I did these changes I put the coolant in between the Max and min line like it says on the manual and sometimes after a long drive the coolant in the reservoir would be filled to the top!! I’m not sure what it could be, my oil seems fine and not milky so maybe it’s not a head gasket or maybe I’m wrong! Any guesses as to what it could be? Hoses? Definitely the radiator again, but what else? HG? View attachment 50496
