Need help! please

What he is referring to about the radiator is sometimes the front of it can get clogged with leaves/bugs/etc. Make sure that there are no obstructions in front of the radiator. Otherwise it cannot do it's job.

I wouldn't use water instead of coolant. And I would not run it without a tstat. At least, not for long. I ran with a failed tstat for a few days while the new one was on order. Tstats now are designed to fail in the open position, so that would create the same environment as no tstat at all.

So do the bleed test when I have a thermostat, or it wont work correctly. and yup my thermostat got stuck open.. but I thought you can run cars with no tstat or is that no longer possible with newer cars..

Also i need to check my front of the radiator to see if the flow is good and nothing obstructing it ?

So any other suggestions that could help with the situation.. i have the mechanic doing a radiator flush and installing the thermostat

 

[pektel]

Yeah, give him the specific instructions for bleeding the system.

Maybe have him do a pressure test too.

It has already had a pressure test ..

Is the coolant actually flowing? I haven't heard of a water pump going bad on an LS, but you never know.
