[quote name='Larry Currie' date='Mar 2 2005, 04:37 AM']I guess with the new fan switch and Royal Purple I'll have a problem with the engine getting warm enough for the heater to work. <img src="/forum/images/smilies/968/blink.gif" class="smilie" alt="" />

Actually, your heater will work just fine if your coolant thermostat is working properly. The thermostast's only job is to maintain a minimum engine temperature, so even if you are motoring in -42 deg F, the engine will eventually achieve and maintain 195 deg F (or whatever the thermostat temp is).
