Also, if you have a hose in hose set up, if there is an internal leak, you may not see it at the fittings. Check your veggie oil for coolant contamination.
Also, since you have the Aux Water Pump wired to run when the ignition is on, I hope you wired in a 1 amp fuse to protect other items ons the same circuit.
I installed an inline 30 amp fuse for the aux pump, just to be safe. I'm not sure I understand how a leak in the HIH can end up coming out near the area of the water pump. Wouldn't I notice a rough idle and white smoke if coolant was in the VO? The car seems to run better on VO as it is. I can see the general area where the leak is occurring; its not a situation where I'm losing coolant and can't find an external leak source.
I drove it several times today. After a 15 km drive, I parked it in the driveway(slight incline) facing downhill and it leaked at least 1/2 litre steady for 5-7 minutes. I replaced the lost coolant, then drove it the same distance 1 hr later, parked it twice in dry parking lots, and it didn't leak a drop when shut off. Both instances were in town driving.
I guess when the system is hot and under pressure, something is letting the coolant out, I was just wondering if these symtoms I'm having are typical of a failing water pump,or its gasket. The water pump isn't making any funky noises at all. The mileage is higher and perhaps the increase in demand the VO kit has made on the pump, its decided to wave the white flag.
What is this tool called to pressurize your system when its cold and where has anyone borrowed it from? It'd be easier dealing with coolant issues on a cold car rather than a hot one
Thanks for the input
