Estima engine overalled now heating up how do I bleed cooling system

You should have a vacuum puller, but alternatively, you can purge it by letting in freon on the low side and opening the high side for about 4 seconds, that should purge all the air in the system.

Possible trapped in system. Bleed system, should have two small screw bleeders, one in front of left valve cover on pipe behind water pump and the other on coolant pipe outlet as you follow upper rad. hose towards engine. Engine cool, remove rad cap, open both bleed screws and fill rad until coolant flows free out both bleed ports. close both bleed screws, rad cap off, start engine and let idle until upper hose is hot to touch , shut off, let it cool down for 20 minutes, top up rad and install cap. restart car ,drive and check.

May need to bleed the air out of the system after the hose change. Look for small bleed valve on the top engine or cooling hoes/pipe bleed slowly while engine is at operating temp, then refill after reservoir after car cools down

If everything is working correctly; thermostat, heater core, water pump, head gaskets, etc. Then that leaves the radiator cap, the overflow hose or the overflow tank as being the problem.

As the engine heats up the coolant expands flowing into the overflow tank. As the engine cools the coolant is drawn back into the engine from the overflow tank. but this depends on the vacuum created by the cooling liquid. the radiator cap has a "valve" that lets pressure out and vacuum in. If it fails then you may not achieve a good vacuum. The hose that connects to the over flow tank must be non leaking as well; if it leaked then coolant would not be drawn back into the engine, only air would be sucked in. And lastly the coolant has to be drawn from the bottom of the overflow tank. again we dont want to be sucking air.

Some engines require a vent screw to be opened when bleeding the air out of the engine.

Theres a strong possibility being you just changed the coolant a few weeks ago that theres air in the cooling system not allowing the coolant to cirrculate properly, look at your top radiator hose is theres a small bleed valve at the top of the thermostat housing when the upper hose attactes to? If so loosen the bleed valve and allow the cooling system to purge the air out of the system you can tell when the air is out of the system when a steady stream of coolant starts to flow out of the bleed valve, if theres no bleed valve take the top radiator hose off of the engine side and allow the cooling system to purge the air out through the top of the engine that way, but it definatly sounds like theres air in the system not allowing for the cooling system to cool properly...

just slacken off the clip on the highest water pipe to allow steam to escape, topping up the expansion tank as you go.obviously when the engine is hot....
