I was heading to work today and with my AC on it felt like the AC stopped blowing cold and my car started heating up the Temp went up to 260 and i shut it off. The fan is working I let it cool down to 180 and started it to drive home and the temp was going up around 230 again when I got home. What could it be?

 

The coolant isn't circulating for some reason. Could be as simple as a large bubble, or a restriction, or bad water pump. Could be a bad thermostat but those usual fail open rather than closed.

 

I'm going to try changing the Thermostat and hope that fixes it. the Crazy thing is I've been looking at new cars and was planning on trading it in this week or next week.

 

Happens every time you think about trading something. 2 different jeeps did it to me, a camaro, and a mower. All had issues the day of or the week of.

 

They know........ I was worried my "daily"/long range car was going to break something when the SS showed up in the driveway.

 

I changed the Thermostat with no luck. It's still heating up. I really don't want to put anymore money into it. It's bad enough the dealer only wants to give me $3,000 on a trade in I can't see putting $500 into fixing it. Maybe I would be better off parting it out.

 

It was alittle bite low but nothing crazy. Maybe 1/4 of a gallon of antifreeze and now it seems like what I put in it after doing the thermostat it pretty much spit out of the overflow tank. I'm not seeing any water in the oil or really anything on the ground except what looks like is coming from the overflow tank from bubbling back.

 

I took it to my friends shop he said the timing chain jumped and it needs to be replaced. it may have also blown the head gasket he'll know more when we digs into it a little deeper.

 

If the chain jumped I hope you didn't bend any valves.

 

I don't think it did it starts right up and runs good no noises or anything crazy like that. No water in the oil or smoke from the exhaust.

 

balance shaft chain broke ...

 

The shop I took my car to said it didn't jump timing but the chain needs to be replaced and said the head gasket is blown. They said around $1500-1800 to fix it. sounds like alot of money to me. Do you think I'm better off parting it out or selling it as is?

 

ya but there is 2 chains one is you timing chain and the other is your balance shaft chain which also controls your water pump its not a hard job to do if you have worked on vehicles before the kit is around 350$ the head gaskets never go on these cars unless you let it overheat extremely take it to another shop to make sure . and if it is the head gasket it is around 500 in parts for everything needed including timing set and should only be 5 hours labour at the most but thats me i dont know how long these mechanics take to do things lol.

its a 09 lnf dont sell it at least fix it first before selling or your loosing your investment

 

Look up basswaves on here, iirc hes in NJ and knows how to fix these cars, he'll do it right and likely be cheaper than a shop.

 

why do they think the head gasket is blown and why do they say the timing chain needs to be replaced?
