Title: Works well, eliminated a factor
Review: I guess I was ready to settle on the fact that my ancient 1986 300zx was ready to be put out to pasture. Initially I had a small coolant leak from the heater hose going into the head that managed to spray coolant over the entire engine. I replaced the heater hose, but the car began to overheat. I replaced the thermostat and had the system flushed, but it still overheated. So, I bought this to eliminate a potential head gasket problem or cracked block etc. I was surprised to see that there were no exhaust gases in my coolant system (the indicator read negative). As a cheap step (before I replaced the water pump) I replaced the radiator cap and the overheating problem went away. I will keep the kit around, for later use, but the negative result this time appeared accurate, and the old car just keeps plugging along.
