'99 sunfire question. (I know this is bonneville forum)
If this is the wrong place for this question, sorry in advance.
My sunfire has been leaking coolant and running hot when sitting still, and the coolant system light is on.
Mechanic told me my bypass hose is leaking, needs to be replaced. Need to replace the thermostat valve and flush the system.
said he'd do it for $260 plus tax. Is that reasonable?
Except for flushing the system, can i change the bypass hose and/or the thermostat valve myself?
I did swap out the blower control module on my '93 SSE, thanks to you guys and that was no big deal at all.
Is this issue more sophisticated? I don't even know where the bypass hose or the thermostat valve are on the engine.
