The first time I took apart the dash of my C900 was quite an 'experience', but now it's routine and apart from the bugbear of needing to remove the left speaker each time I need to guide the heater control rod back into place on the control valve shaft (refer to "http://nospam/~c900/heatervalve.html" for more info about C900 heater control valve replacement), it's not too bad. lol >> No worries ...

Or 4. ;) > >There is no 4 ;) 8-) One way to check the cooling system appears to be working is by starting the engine and feeling the hoses every few minutes as the coolant starts to heat up. You should feel the hoses to the heater control valve warm up first, then the big hose to to expansion tank. Then the big hose at the top of the radiator should begin to warm up as the coolant does it's job and heated coolant starts to appear at the top of the radiator. What worries me about my C900's is that they both have the top radiator hose split half-way to install the additional thermo-switch housing that I believe is something to do with the air-conditioning controls (?). Those hoses get extremely stressed because they're both short and set up as two 90-degree bends, and one of them is quite swollen just from age and use. I'm trying to find a place which sells 1.25" ID silicone 90-degree 3 or 4-ply hose bends but so far have had no luck - only 1.5" ones and they're too big.
