So I thought I had the overheating issue fixed but it got hot again yesterday and the coolant was low. I replaced the HG only a couple months ago, new water pump only a couple weeks ago, new coolant, newer silicone rad hoses. Can't find any leaks even when it's running, mishimoto rad that is not visibly leaking, new cap (tried three different caps), fans are working fine and kick on normally. Burped the system multiple times and it works fine for a while then it starts to get hot. Gauge never reaches all the way hot just about 3/4 then drops to normal, doesn't get hot when sitting still only after boosting and putting the engine under load. The system must be loosing coolant somehow but the car is running great and the coolant isn't bubbling like the HG is bad. My last option is to replace the thermostat, unless somehow the turbo is causing the coolant to become excessively hot? I'm so tired of messing with what should have been a simple fix.
I'm sure you did already because you are one of the smarter MSP owners lol but I'll ask anyways. Did you burp the system?
