Cvic VTI Thermostat

Has anybody got a schematic of a VTI engine or a link to one on the web.

I have just bought a 1998 Civic Aerodeck 1.8 VTI and the heater is not
getting very warm, so I thought I would order and change the thermostat.

My problem is which bit do I undo to replace it.

Thanks

Here's a drawing of the part of the cooling system that
holds the thermostat for a 98 Civic GX. If that's not what
your Civic is, follow the pointers to put in your car's
info. The thermostat should be under "water
pump-thermostat."

If it's a lack of heat going into the passenger compartment,
but the engine temperature gage reads fine, other things
could be causing this. Keep checking back, or google.
