My 85 toy 4runner 4wd having problem of blow out the coolant through the small hose that run from next to the radiator cap to the small coolant tank everytime I drive for like 20 minutes.
I replaced a new thermostat, new radiator cap and a new radiator same time, about 1 week ago. Still give me same problem. The water pump is replaced about 8 months ago.
What else can be that faulty of blow away my coolant?
