I have changed the sensor under the battery tray but can't get the water señor light to go out. Is there a correct way to bleed the system. It's a 4th gen trans am

If its the water instrument light check the water expansion tank float is working correctly.

Errrrr how do I do that

there is a sensor in the radiator on passenger side below top hose I think

there are a couple of bleed screws one near thermostat housing, one in a T piece on heater hose at front of engine near alt.

Will take a look how do I check if it's working

check resistance across terminals with and without water and with hot water covering it
it should alter

Does anyone live near Buntingford to go through this with me ?

Buntingford, in Herts ? Why not take it to Rocky, American Technique in Watford, or Robin, Autopontiac in Hounslow, West London

For the coolant level sensor mounted on the radiator, below the radiator fill cap, next to battery tray.
Check radiator and expansion reservior are at the correct levels. Then for 5.7L engines, turn the ignition from On to Run then Off, otherwise the LOW COOLANT light stays on. Hayes manual 24017. Pages 1-24 & 1-25, (30.13 -> 30.14)

Have been told it could be a head gasket by a bloke in work so now panicking. It starts and drives fine. No smoke no oil in the filler cap and now water from the exhaust. Also no power loss. In a worse case scenario how much would that be

is it losing water then?
if not then probably not headgasket
if water is blowing out header tank or disappearing then maybe
as suggested above, Robin or Rocky could test it
or ask a local MOT tester to check header tank for hydrocarbons with emission tester

Is rocky on here. As it am a complete loss to be honest

No water loss I can see just overheating from time to time

could be thermostat or cooling fan not coming on, or if your lucks out them headgasket

this is Rocky
