This car drove fine all the way back from NJ, which was in february but now it keeps overheating and smoking. I brought it to the infiniti dealership in my area and they "flushed my system" for $300 bucks and the car was fine for about 3 weeks but then it started over heating again and now it's smoking as well. I had a couple of mechanics look at it andeach mechanic said something different. It could be a head gasket (I'm getting a syrup like smell and the smoking coming from the right side under the hood), water pump( there's a noise when I drive and the car has to run for atleast an hour before the heat gets even warm), and/or a sending unit sensor because my car goes from cold to hot in a matter of minutes without the car running for long. Can anyone out there help me or have any suggestions?

Thanks in advance

Where are you located? You can reach out to local forum members to see if they can point you in the right direction. There are a lot of knowledgeable people on here. Welcome to the forum and good luck!

 

Are you loosing coolant?

I can only guess but if the previous owner new there was a coolant leak he would top off the coolant and it will drive fine then start to heat up after it leaks out. Your dealership refilled everything and same thing happened 3 weeks later.

Then you have your mechanics saying the issue is something big so they can make a quick buck because they know its probably going to be an easy fix.

thats a lot of speculation haha

 

I know a lot of ppl don't like don't like going to the dealers but if you can make it there and pay the big bucks to get it fix I would do it. Did you check your coolant?

 

Is the vehicle throwing any codes?

 

Yes I am losing coolant and I wouldn't mind bringing it there but the customer serivce really sucks. When i called back to confirmation that the car was dwfinitely worked on , the guy on the phone stated that they didnt do anything to my car but I have a receipt and that's why I'm apprehensive about bringing it back there. I had a diagnostic read and it said something about a sending unit. The car only has 85,000 miles and was in a front end collision. Idk what to do at this point

 

Ask other members in your area for a recommended non dealer mechanic that specialises in Infiniti/Nissan.

 

You'll have to get the car looked at. Hard to really diagnose over the net other than throwing out random arbitrary guesses. With a front end collision, it's also possible there is mechanical damage to the engine that was overlooked and is a recurring issue. Hard to actually see this without eyes on the engine

 

I'm betting you have a leak in the cooling system somewhere. Could be in any number of places although since the car was in a front end wreck it's most likely to be in the radiator. A competent mechanic would have done a pressure test of the cooling system with fluorescent dyes and UV lights rather than just flushing the system. This would either show you where the leak is or rule out a leak.

Find a competent non-dealer mechanic to take your car to.

 

Shelia, rather than taking your ride to a stealership that sucks try Nissan! I've found their mechanics are better trained and they charge 30% less than Infiniti. Finding a coolant leak isn't rocket science, you could have a radiator shop do the job if it's in the cooling system...they're the best at finding overheating issues!

try replacing the head gasket or the radiator?
