Remove the inlet hose to the heater core and run engine to see if you have flow. If not suspect the water pump. Check the radiator cap too. If there is good flow, then see if you can get the air out of the system by vacuum fill or jack up the front end to bleed all of the air pockets. Be aware that when you use a vacuum fill device that you MUST pre-fill the fill hose before you throw the valve open.....and it helps to start with it as empty as possible before ya draw your vacuum and just make sure you have enough 50/50 mix to do the WHOLE job....never letting it get even one gulp of air(from start to finish).....and PRIME that fill hose first,if you don't that will defeat the purpose of the tool. Touch both radiator hoses will tell you that the radiator get restrict or not. Still no heat then replace the radiator. Hope it help
