    Whining noise only after warm up

    This rotation only noise might be the rear end generating a high frequency pitch. Does the pitch become louder ascending a hill under a heavy acceleration? I had this issue once with a remedy of a fluid change with Red Line Light Shock Proof gear oil including about 4 to 5 ounces of Nanotech...

    Harsh reverse engagements

    I have two LS 04 & 06 with the same issue. The 06 has about 120k purchased at 65k and $1xxxx later. The harsh shift into reverse gear was a continuous issue when the hammering of the rearend & joints to rubber couplings was solved by enlarging the transmission lines diameter to 5/8 ID hose. I...

    3.9 Throttle Body Hose Swap to Hardlines

    Hi, after cooling system work is complete and cold, I fill the degas tank about an inch from the top and start the engine. McMaster-Carr pn# 47205K37 90° valve closed & cap 16lb rating on the degas tank. As the engine warms feel the rad hose gain pressure. The engine is warming the air and...

    3.9 Throttle Body Hose Swap to Hardlines

    The hose location and the single fabric braid caused to look elsewhere then oem parts. I had shorter throttle body hose failure show up only when the engine was summer freeway ran. Check out ebay auction # 135595473850.

    3.9 Throttle Body Hose Swap to Hardlines

    On the hot coolant tap that runs to the throttle body, I found a 1/4" steel braided hydraulic hose will fit tightly clamped by a PEK crimpes ring and routed under the intake manifold PS back the throttle body. Clamped 2x on the front cover because of the hose rigidity. It was a one and done...

    Change the Coils… not always the answer

    I'm glad you had good service from the plastic cooling parts and improvising an override fan swirch. The thermostat retaining ear can be reinforced with a countersunk 4-40 screws which seal fine with a #42 drill. As for the plastic cooling parts they're all 6061 aluminum now. When the mystery...

    Change the Coils… not always the answer

    Go invest in a Fluke infra-red thermometer and point it at the exhaust manifold covers when fully warmed up. I'll find those two locations are the hottest parts in the engine bay. The manifold covers have one mica sheet sandwiched by two aluminum shells that are to shield the heat method. That...

    Rough shifting and Reverse jerk.

    Well you might not have considered the metal wear that is present in the transmission oil can affect the complex assemblies within the case. Have you considered chromium contained within the gears, shafts, ete for instance becomes magnetic say above 38°C or 100°F. Chexk it out. Or coarse the oil...

    Other possible locations for coolant leaks? (01' LS)

    This is what I end up curing the mystery leak with a steel braided hose with a pek clamp.the routing not seen is atrached to the ds cover threaded holes to hold then on to the throttle heater input line. The hose is a ten to fifteen minutes effort.

    Liquid, the thermostat housing was the last of the plastic to 6061 conversion. I do believe that part is in the long list the machinist is working on. He has the Motorcraft thermostat parts bag to ensure proper fitment. The DCCV for the heater core control hasn'tever leaked but moght ask him...
