My car drives fine for a little bit and has a issue where it won't accelerate and rapidly overheats. After the [engine](/topics-engine-chevy/) cools down it drives normally again. Is it bad [spark plugs](/topics-spark-plug-chevy/)? Mechanic's Assistant: Have you checked the coolant? Have you checked for a leak in the cooling system? I just got coolant work done a few months back to fix a leak.. it doesn't seem like the coolant level has gone down in months though Mechanic's Assistant: What year is your Spark? It's a cobalt 2006 Mechanic's Assistant: Are you fixing your Spark yourself? What have you tried so far? It all started when i got a oil top off at jiffy lube and they put too much oil.. i got a oil change after that and it ran pretty smoothly for 5 days. .now the same issue is occuring

Hello and thank you for using JustAnswer. My name is \*\*\*\*\* \*\*\*\*\* I will do my best to assist you.. I help many customers, so sometimes my replies are delayed, I will respond once available. During this conversation you will be given an automated offer for a phone call. You may accept or decline that offer.I don’t personally offer this service so if you take this another tech may call. To me that sounds like a faulty interment thermostat, you would want to have the fans checked to be sure they are working as well when it overheats, if the fans are ok I would replace the thermostat.

the acceleration (or lack there of) is because the engine is too hot?basically the faulty thermostat isn't kicking on the [radiator](/topics-radiator-chevy/) fans in time?
Automotive Expert
yes if the engine is too hot it will not operate correctly and the thermostat and fan are 2 separate issues

Thanks

your welcome
