Heard the Waterfall sound today behind my glovebox. Noticed a leak around a gasket under the throttlebody that has a few hoses coming out of it. My local AutoZone doesn't carry this part. Anyone know what it is called and who carrys it. Also has anyone had to replace this before. Is it OK to keep driving untill I get it fixed. The Heater seems to work fine but from what I read it means that I have air in the system. Also justed had the Service Engine Light come on. The code is the P0455. Should I start by replacing the gas cap. If so should I buy a OEM or after market. Can I reset the code myself or is this a job for a pro. The truck has 59,000 on it now and I am looking at doing the 60,000 mile tune up in the next month. Can I find all the DIY threads on this site on how to perform all the tasks for the 60,000 mile tune-up.

Keep the coolant full, check it everytime you drive, drive youir wifes car and leave the truck parked as much as you can.
If you overheat the engine you will be buying a new one.
