No, actually, there's a dealer about a half hour south of here. Still a PITA but not 2 hours at least
JPFX35 said:OK ... So far, so good. The dealer had my car for about 1 week. They determined that the radiator cap is the root cause of all of my overheating problems. So they replaced it. I have had the car for three days now ... and no problem so far. Also, I am noticing that the temperature gauge is holding at a level just a little bit below where it was for the last few months when I was having this intermittent overheating issue. Maybe this is going to work !
I am still a bit confused .... As I stated in an earlier posting, the radiator was replaced (around Mother's Day weekend of this year) ... I would have assumed that a new radiator cap would have come with it ... I can understand why my old radiator cap would fail at 100K miles .... but is it possible that the dealer would even think of using the old radiator cap on the new radiator ? The service rep said that this was the case. If this is true ... then I have confidence that the problem is resolved. However, if they are not telling me the truth ... then I have reason to be worried. Can anyone shed some light on what happens when a radiator is replaced ? .... does it come with a new cap ? or does the dealer have to go get one off the shelf ?
Hi GapmanI have the same problem. I started a Facebook group, becuase i think we could all have a class action suit...
I changed my thermostat, did a block leak test, then i noticed my fans wouldn't run the low speed, and would only come on when my ac was on.I checked the fan relays (their are three) they were good. I wired the fans direct and one started up right away, the other would only start if you spun it a little by hand. I bought a fairly nice set off Rockauto, popped them in (they are extremely easy to replace) and the temps have been rock solid since. I will be doing the coolant system flush soon, but for now the fans did the trick. just my .02 hope that helps.Hello Everyone, I'm having the same problem. I took it to local shops who thought it's a head gasket issue. I've been driving w/o a thermostat over a year w/o overheating and w/o heat in the cabin. Once the cold air hit NY, I thought let me spend some money and fix this no heat issue. The worse decision ever. I took it to the dealer and spent over $1100 on my '03 FX35 and they couldn't figure it out!! They tested the exhaust for antifreeze smoke I guess to see if there was leak from head gasket to the engine(if possible). That was negative. They think there's blockage some where within the engine or somewhere with the coolant system. This is the dealer telling me this mind you! They have absolutely no idea where the issue is and are clueless on this the engine they're suppose to be an experts on, outrageous! They said it would cost me $4K- $5K to fix it and if they do conclude it's the head gasket, it would cost me like $15K. What a joke?
It's probably something simple but who knows what it is? That is if someone from here maybe already figured it out.
Now, I can drive for about 10 miles w/o an issue with a high rate of speed(60mph) and then I'd see the temp gauge slowly creeping up to getting hot. It doesn't overheat though. It lingers between the last two lines on the gauge. When I pull over, it slowly cools down even when the engine is running. The odd thing is it warms up initially and the temp stays at normal temp(mid point of the gauge) for a while and then it starts to creep up. If it was something severe, I'd think it would just keep on going up as soon as the engine is warmed up. I should also mention that I removed the thermostat again.
WAS ANYBODY ABLE TO FIGURE OUT WHY IS NISSAN ENGINE DOING THIS?
Please let me know if you were able to figure out what's causing this issue.
First, I would like to thank the users of this forum for the excellent source of information on the infinity fx series. I recently bought an fx35 06 @ 180KM, everything seemed fine first, but after driving the car for sometime following my purchase it would shut down while driving, I went to a mechanic and he ran the computer, so I changed the cam sensors as those were causing the problem. now how does this relate to overheating? well, after the sensors were changed, everything was fine, but then overheating started to happen. I noticed as OP stated that my reservior started to fill until its full then the car would start to overheat. Thanks to the information provided, I did as advised and changed the fluid, bought a raditor cap and changed the thermostat. changing the thermostat took 15minutes, its important to note that in order to ensure the new cap is not faulty, you should disconnect the reservior from the radiator to see if fluid leaks when the cap is on, if it doesnt then your good to go. Everything is back to normal and the car is no longer overheating, one thing to note though is that the new themostat needs sometime to "train", I noticed it would rise slowly until it goes over the middle, I was advised this would happen and to top up the fluid once the car cools down, this happens because the thermostat is opening its valve to allow water to enter the engine, and this displaces the fluid which needs to be topped up. so I did it once. Thanks again.Agreed... the engine cooling system on all cars hav ethe same or similar components. When troubleshooting is easiest to start with the cheapest things first and the things you can change yourself. In order of troubleshooting:
coolent level and mixture (not just straight coolant)
fans (does car overheat at idle, cool down at highway speed)
Your problem sounds like a thermostat. When it is running hot, does the large top hose from radiator to engine swell up?
OK ... Back to square one. I have driven about 700 miles since my radiator cap was replaced ... and since then it looks like the engine is running cooler than it had for months according to the temperature guage.
However, today on my way home from work, I notice a gurgling sound behind my steering wheel, while I was starting up my fx35 and driving out of a store parking lot along the way home. When I got home I checked under the hood and the overflow tank was over the MAX line. Also .. I noticed that it was bubbling inside.
Tomorrow morning I am driving back to the Infiniti Dealer. I am really getting tired of this.
