[RICK LAKE]

rtstrack Any chance of getting a couple of pictures on this? You are saying surge tank, do you mean overfill tank or is this something different? 16 psi cap are high enough. If there is a nipple on the radiator filler neck and it is lower than the Filler tank on the motor, cap it. There should be just 1 line going from the filler tank to the overfill tank. If working correctly when the motor is hot, the coolant expands and goes into the over fill tank. When the motor cools off, the vacuum sucks the coolant back into the fill tank. You may have to go to a 18 psi cap on the radiator for this system to work right. Get a couple of pictures if you can Rick L.
