Hi, first post. 2months of ownership of a M139 sport GT 2007
So when I got the car I did just drive for bit without really checking anything. The car seemed mech A1. I noticed when stopping for a while at times where I have been going slow, the overflow for the radiator bubbles and gurgles. That to me sounds like boil over. The thing is, the temp guage never goes over 90degC. I've never seen it go higher and I've never got a overheat warning etc.
I decided to give it a bit of a look over. The coolant seemed low so I followed the manual, set the climate control to max hot to open the heaters and filled to correct level. Did a long drive and some slow driving before stopping. When stopping coolant overflowed all over the ground. Since then, the coolant level has obviously gone down. The tempt gauge still doesn't go above 90degC and it gurgles when driving slow and stopping like it is overheating.
Two theories here - 1. blown head gasket. Probably should get the coolant system sniffed for combustion gases. 2. bad thermostat. Should just replace it anyhow.
Anyone seen this? It's almost like the gauge is broken or they purposely didn't allow it to go over 90degC so as not to scare the driver (seen jeep do this with oil pressure because of complaints). That is jeep showed a fake oil pressure so drivers didn't get worried at idle! It's odd that it boils but temp gauge is not high.
thanks.
