[QUOTE="jarance, post: 583173, member: 21"] based on my experience, mechanics tend to change hose #1,3 & 5 because they are easily accessible. They tend to skip hose #6 and 8 because it is a major job to change them. Major job because they have to remove the air intake manifold, fuel rail, firewall cover, etc etc to get to the hoses. I also have change the 3 hoses as you have mention but the leak still persist until I find the leak from the hose # 6 and 8. and yes, there was no leak when the cooling system was pressure test with a air pump. I found a a way to check the leak. First is to fill the radiator to the brim. close the cap and start the engine. Once the engine is warm up, rev the engine speed to above 3000 to 4000 rpm for about 3 minutes. what you trying to do is simulate a running condition. Stop the engine and check for water droplet. Trace the droplet to the source and you will find the leak. remember to drain the excess water after the test. [/QUOTE]
