Vr flat battery, overheating help

[audiosoup]

hello

I recently started getting flat batteries. I checked out the old battery.. it was a bit ratty so I decided to buy a new one. Once it was installed, I dunno whether this is normal but the first two times when i went to go in reverse it stalled which it neva does.. i thightend the cables and it worked fine after that.. but then i took it to melbourne.. about 40 minutes into the trip that car was overheating and pushing past the H on the thermometer, i was in heavy traffic so i couldnt pull over. Though I put the car into park for about 30 seconds.. and after that it went down. On the way back it was fine and hardly came off Cold... any ideas why its doing this? I have checked the belts and water in the radiator. IT may be the crank angle sensor? IF it is, is it still safe to drive the car when it goes that hot?

thanks for any help guys

could be air in the head?? my vr used to go way past the H when it got some air in there, undid the breather until the coolant came out and shes all sweet now

Has it only been doing all these weird and wonderful things since you replaced the battery?

Perhaps dis-connect the battery and remove, clean both terminals for the battery and check your earth straps etc. replace the battery and make sure your terminals are secure.

Could possible be a crook connection somewhere causing electrical errors with the voltage drop.

Only a guess but anything is worth a try.
