Overheating Problems!

Well i changed my pressure cap to the factory standards 13 lbs and changed the hoses and flushed the system. After 30-20 mins in to driving the temperature starts climbing, i pull over and check and my overflow tank is full and squirting out. I have the 1987 Rx7 GXL version and it has two caps? One on the thermostat housing and the other is near the overflow bottle.Theyre both 13lbs or they both say 0.9. And the overflow hose goes into the radiator directly not on the thermostat housing. Please help me!!

are you looking coolant or smoking? sounds like you just have a dying motor. If your temperature starts to go over half stop already! Don't wait for it to god damn over heat and spit coolant. Your destroying your motor if it isn't already dying.

Yeah kinda sounds like coolant seals...
There's plenty of shops in CA though...there's a thread stickied in this forum. If it is the coolant seal you're looking at $1000-$3000...tons of factors involved.

Stop driving it then. Your going to make it worse if you don't fix the problem.
