J. Anderson Posted June 14, 2013 Share Posted June 14, 2013 Heyeveryone I came here hoping for some advice on some issues I've been havingwith my 2003 Camry. So about 3 weeks ago I notice some issues, my car has120,000m on it so I know its still has a lot of life. But, first I notice whenI turned on the heat cool air was blowing out (Thur/Fri), then my temp gaugestarted to go to the very top or overheat, the next day I had the thermostatreplaced, but the heat didn't come on until I rev my car idle to 2000rpm. A daylater I felt a vibration in my car, then the next day upon start-up my car wasviolently vibrating but calmed down. I took it for a drive that night and onthe way home while driving it started vibrating violently and my engine lightstarted blinking. When I finally got back home and pop the hood it was smokecoming from the engine. I took it to my mechanic the next day and heimmediately said I needed a new temperature switch because the fan wasn'tcoming on when suppose to, which was causing my engine shake (The guy who put in my thermostat kind of noticed the same thing). He replaced the temp switch, Ipulled off and when I got home and restarted my car about 5min later the enginestarted to shake again but not as violent and temp guage went up. I took itback to him immediately and the code read a cylinder 2 misfire and he noticed Iwas losing coolant. He kept it overnight, and added that blue devil leakagestuff, which seemed to fix the problem. He told me to change my coolant in twoweeks, and when the second week came and I turned on my AC the temp guage wentup again! but went back down after some driving then back up again. I did myown little coolant flush because right now money is scarce and that initialwork really spent me, from watching videos that day and after some time itfinally was back to normal. When I first did the "flush" I turned onthe heat but it was'nt hot, so I rev my car to 2000rpm and the heat in my carbecame really hot as if it was working right. I drove my car around for like20min with the heat on high for half and air on high for half and my car seemedto stay at the normal operating temperature (the gauge was in the middle). Thenext day I drove with the Air on and it was raining and the gauge read normal.The next day I had a feeling and when I pulled into my parking lot, placed mycar in park and turned on the air my temp gauge went up, but not all the way toH though. When I rev the car to get the heat pumping the gauge went down alittle to the upper line of the normal. I forgot to mention that prior to thiswhole incident, whenever I would run my A/C while driving, when I would parkand turn my car off I would hear some gurgling or dripping for some time aftertoward the passeger side of the car. I'm thinking that it could possibly be theRadiator cap or I need to bleed the system, I really don't have any money totake it to the shop..any suggestions what the reason could be????

Daniel Stevens Posted August 11, 2017 Share Posted August 11, 2017 Hi! I have a 2003 Toyota Camry with 411,000 miles on it. And I have had some of the same issues. I'll explain what I can lol. I had three misfires in mine at one time. I basically ran on one cylinder for a bit. Until I could get the $700.00 to fix it lol. It was shaking as you described and the check engine light would blink. I replaced all four injection coils and not the plugs because I was told they had been replaced. Found out today they weren't. So I replaced those and one of my ignition coils got super hot on the bottom rubber part and was really dry and the spring popped out. So I ended up getting one replacement since I had the warranty. After all of that the car ran like a champ!! Till five minutes ago lol. My girlfriend is telling me the temp guage is between normal and overheating. Normally it doesn't run that high. She looked under the hood and nothing was leaking or she didn't notice anything. I hope it's just a temp guage problem, but there is no telling.

Toyota Owners Club Posted August 15, 2017 Share Posted August 15, 2017 first thing I would check or even replace for the small cost involved would be the radiator pressure cap because if that is failing on maintaining a constant pressure then it allows the coolant to boil up quicker. Any ignition misfire would only contribute to higher engine running temperatures. Also, check the main engine cooling fan is operating correctly Quote Link to comment Share on other sites More sharing options...
