Just a quick follow-up.

Could someone tell me the book hours for oil cooler replacement, thermostat replacement and heater control valve replacement?

Also, has anyone replaced, or thought of replacing the hard oil cooler lines with flexible lines?

Thanks.

Burning Oil odor went away after a few days. It must have been residual oil that spilled when filling.

There was one hose that did not appear to be connected, and if I re-call it was not connected prior to dis-assembly. Also the end does not seem to be distorted as is typical when fitting a hose to a barbed connector and tightened with a clamp.

Is this a drain hose, or does it need to be attached (vacuum hose)?

See photos.

Thanks

Thats the auto box breather hose and does not need connecting to anything.....

Very clean engine bay by the way....

Any chance you could take a pic of where the aux electric coolant pump bracket attaches to the cruise control unit under the coolant expansion tank.....its rare to see this in the Uk and a common question when upgrading base model Omegas to cruise....

Yes, it is clean

, my dad got the car back and noticed some white grease on the engine compartment, and had to immediately wipe it off. I use the grease in my socket wrenches to capture difficult to reach bolts. I told him the grease helps to preserve the engine

.

Instead of posting the photos of the cruise control here in the Coolant thread, I started a new thread:

Let me know if you need anything else, as I do not think I would have had any fun trying to solve the coolant leak without your insight.

Thanks Again!!!

after reading this im gonna put in my problems.

yesterday my coolant light popped on. i topped off with DEX and was on my way. this morning on lunch break my light came back on. figured i would top it off after work. while my car was sitting outside i noticed that something was leaking from under the car, BAD.

i brought the car into the bay and found i was leaking coolant on the back of the engine. i looked between the trans and the passenger side exhaust and saw a mass of coolant on what looked to be a T hose?

is the heater control valve around there?

The heater control valve is much easier to replace.
You can remove the two halves of the cowl and get sufficent room to access it without having to disassemble the engine at all.
The oil cooler takes removal of all 3 pieces of the intake.
It could be either, but it is hard to tell unless you get in there and look really well.
