Thank you. Seemed like a novice question I know - but there is so much information about the closed systems - figuring out how to maintain the one I have is much appreciated.

Thanks to both for your comments. I checked the hose in the overflow tank and it is indeed notched as you indicated. My question (albeit a novice one) is to what level and how to add the coolant if necessary? Do I open the tank, let the car run until the thermostat opens and then add coolant leaving a small air gap at top of the filler neck? Do I add to the overflow tank and watch to see if any is drawn back? Heater switch on or off? I have read many of the posts about a closed system and I am likely to make the switch in the future but in the interim - just looking to make sure I take care of the one I have properly. Many thanks for your further responses.

Hi folks, looking for some help on this. I have an 89 1700 x-flow with an unsealed coolant system and a coolant overflow tank. I am trying to determine the correct procedure for checking the coolant level and adding if necessary. I have determined I don't have an expansion tank - as it is an unsealed system. I checked it on the weekend cold and without the thermostat open there was no visible fluid under the cap. No over heating issues - just trying to do some basic preventative maintenance. Thank you!

Many thanks!

Hi folks, I have recently acquired a new set of NGK B8ECS spark splugs as per the Caterham manual for this engine configuration. I have the spark plug gap of 0.025". My question is what torque to tighten the plugs to and should I use Copper Slip anti-seize in the installation? This will be first time I change them and would appreciate the feedback for a novice mechanic. Thx.

Hi folks, I have a replacement set of NGK B8ECS for my 1989 Supersprint - Ford Kent OHV2265EV Crossflow. I am trying to determine what is the torque requirement for installation and secondly if I should be applying copper slip anti seize when I do so. Any help? I should add the assembly manual for this engine configuration calls out a 0.025" spark plug gap.
