After replacing the thermostat I am having overheating issues. what is the process on the t that is for bleeding. how long should it take and how would i know its good?

 

I’m gonna take a stab and say this is also why you have no heat. You have air in your system.

Bleeding the LR3 is a bear .. search the forum for some process and tips like using a power bleeder .. once you are done you might have also solved your heat issue.

 

It's a pain in the *** for sure.

How I did it was:

Start the engine and crank the heat on full blast

Opened the bleeder T and waited for only coolant coming out then closed it.

Next I took the cap off the tank and let it work the air out while adding fluid as needed.

Even then still had some air, first 10 min of driving the temp spiked so I pulled over and burped it again. That took care of it. Next couple mornings I just added as needed before starting it

 

There is a bleed on the tank itself which you should open and wait for only fluid to come out. Make sure heater is on max so that the water circulates through heater otherwise you can still end up with air trapped in the heater core.

 

The heater cores on these trucks are continuous flow, turning the heat on max does nothing at all to help the cores bleed. Just FYI.

 

When filling, fill slowly with it running and park uphill, Also helps.
