The ticking sound is a bit loud. Mine sounds like that too but not as loud. I believe brand of oil will make a difference as well. I used to use Mobil One Synthetic 5w30. Didn't have a problem with it. But some people online were complaining about the noise in the winter time with Mobil One. I then switched to Pennzoil Ultra Platinum. It's better for sure.
As for the overheating goes. Probably the t-stat like others have said. I recently had that problem, kinda. My temps usually will read mid 190F in the winter, low 200F in summer. It was the winter time, upper 30s and low 40s. My coolant temp was at mid 200 to 210. Which was weird... That's actually worse than the summer temp? I had a new t-stat installed about 3 years ago. Didn't think it would be the t-stat. I did notice that the upper rad hose is boiling hot but the lower hose is barely warm. Online people say it's normal because hot coolant travels down and rad cools it, so lower rad hose should be warm. Thought maybe it's the fan clutch. Replaced it. No luck. Finally, I decided to go ahead and change out the t-stat (this time with 170 degree one 21200-4W01B) Problem solved! Now the upper rad hose is hot, lower hose is warm to hot.
If you end up changing out your t-stat. Learn from my mistake. Do not use cheap gasket! I used a cheap one and a few months later, it started to leak coolant. And I wouldn't have notice it if I didn't remove the intake to look for a washer that I had dropped. I purchased a better quality gasket (rubber coated) and thought it's a done deal. Well, the old gasket did not come off in one piece... it ripped into many many many small pieces... Some got stuck on the t-stat that would not come off. I even used Citrol 266, the strongest chemical I have to remove ****, couldn't get 100% of **** off the t-stat. I gave in and bought ANOTHER new t-stat. So far everything is good. Hopefully it stays that way.
Make sure you test the t-stat before you install it. Even if it's OEM (and I do recommend buying OEM parts), it can still be defective.
