The car is a 92 jza70 with a 1jzgte. only mods to the car currently are a intake and clutch and electric fan
couple of days ago i notice that it had a little bit of power loss and didnt thing anything of it right away but when i parked the car and shut it off the coolant started to boil. so today i went about trying to find the problem. thought at first maybe just air in the system. went to bleed it out. after about 30 mins of the car idling it finally start to bubble some air out not much tho. then it started boiling again at idle with the rad cap off.
the temp gauge is at normal, it runs and drives fine and no smoke while driving or idling, there is no coolant in the oil or oil in the coolant.
then i figured maybe because the heater hose is above the rad cap to remove that and see if there is air in it and i had no coolant there at all and no flow. so i put the heater on floor and hot. it blows cold air no hot air.
while i was putting the heater hose back on i notice a broke check valve?(picture to come) I am not certain it is a vacuum check valve or not and what it is for. can some one tell me? also i was told that the heater on these cars use vacuum to switch between hot an cold. if this is true is the check valve stopping it from switching to hot and letting coolant flow? if not what do you think the coolant isue could be?
thanks in advance
