- Sat Aug 08, 2009 7:47 pm #136747 So my Coupe overheated yesterday...Kinda werid cause I went to pick up my lil bro..I ran my son inside and left the coupe running, while my bro got his stuff ready. Then after about 15 minutes of waiting, I went outside and my coupe was steaming!! I was like what the @#$*!!! Ran over there shut the car off and waited a bit before opening the hood and steam was coming out my coolant resivor...I looked around and no blown hoses no cracks in radiator that I could see ...My fan kicked on to cool it down....Then when it was cool I checked the radiator...The radiator was really low, added some coolant and checked to see it she would fire and she did with no problems....Gonna go check her out today...Check the Termostat, and see if I got any coolant leaks?? Will see how it goes....

- Sun Aug 09, 2009 2:43 am #136788 best thing to do is keep a close eye on it. Monitor your coolant level and check to see if air bubbles are getting in causing coolant to be pushed into the overflow tank. Put your thermostat in a pan of boiling water to see if it opens. look for oily film or brown gunk in your coolant. (that would mean a bad head gasket) Hopefully the head did not warp...

- Mon Aug 10, 2009 4:05 pm #137004 Well Ive been checking it closely and nothing no gunk or anything in the coolant....Thremostats good, I still keep an eye on her and will see what time tells?? Thanks for the imput Chance!!

- Sun Sep 06, 2009 1:58 am #142008 happened to me once

no leaks of any kind.. just random overheating

turned out it till had the original radiator cap. i bought a new one n the problem went away

i guess the old cap wasnt venting the pressure properly.

hope that helps

- Mon Sep 07, 2009 4:22 pm #142201 thnx for the comment I fixed it and it hasn't done it since..Thnx though..

- Mon Sep 07, 2009 8:22 pm #142232 so what did you change?

- Tue Sep 08, 2009 1:38 am #142289 I didn't change anything just added more collant cause I think it was really low and I bled it to make sure I didn't have any bubbles!! After that she ran fine!! thanks for asking!

- Tue Sep 08, 2009 6:23 am #142337 I'm sorry but you haven't fixed any thing, cars just don't go low on coolant for no reason, you probably have the start of a worn/bad head gasket. or a small leak some where, a bad head gasket will put air into the system, which usually pushes water into the over flow versus taking water from it.

- Thu Sep 10, 2009 12:33 am #142722 Ok but I did a Intake manifold swap a couple weeks before and I didn't fill it up all the way...Which was my bad.. And I am sorry but I got no leaks anywhere!!
