Coolant Hose Sizes

[Larry C Leung]

Hello Listers,

1) Polling the list for those who have BTDT on type 44 10VT (specifically
'89 200Q) whom might know the generic Inside Diameter hose sizes for the
following hoses:

(EKTA not working at the moment)

Water Pump to water pipe (runs along block towards the firewall) Looks
like 5/8"


Water Pipe to Heater [Looks like 5/8" again]
Heater to Heater Valve
Heater Valve to Block


Expansion Tank to Radiator (looks like 3/4"?)


2) Anyone know if the 20V Upper Radiator to Turbo hose (the one with the
stupid Banjo Fitting) works on the 10V? If so, I'm looking for the P/N
and the appropriate hose size that goes with it. If not, does anyone have
the appropriate 10VT part number for this?



3) Does anyone know if it's worthwhile to replace the braided coolant
hose that comes from the turbo to the water pump?



4) Finally, does anyone know of a source/Part Number of the all metal
heater valves that replace the OEM plastic ones? My car has Climate
Control. 



Thanks for all of your help!
