Re: Coolant leak
- Sounds like you might also have an oil cooler seal leak, which can
cause the condition you describe. There is a TSB in the Files
section on this - 01-06-02-009 - TSB - Low Coolant, Leaks, etc. My
contacts say this is a very common problem, especially on cars in hot
climates. If I haven't stuck this one on the Top Ten list yet I'm
about to, as my car has some variation of this one, or a bad temp
sensor (another TSB). Look for the Service Manuals on eBay, they are
well worth it. You can see a list of all TSB titles at Alldata.com
but have to subscribe to get full info. And the dealer should be
able to show you the TSB's if they have a clue - but check the Files
section here for most of the major ones.

- the HCV is black plastic with 3 hoses going to it. It was at one time attached to the block with a bracket but most of the time they are just loose in there now. I reach in and can get to the valve now. Before I squeezed my hands in there I removed the upper intake to get extra room. You can also remove the wipers and cowl to get room or use the access door next to the hepa filter.----- Original Message -----From: willie_69_dynamiteSent: Monday, October 29, 2007 11:41 PMSubject: [CateraOwners] Re: Coolant leak

Not the HCV sure sounds like a freeze plug. At the back of the motor I
bet it will be a B to get to. I wonder if they can just take the mount
loose on that side and tilt the engine to get to it.
