Summer is here and I don't need it. I run a SIIA 1971 88   Michael Noe (Noee) Senior Member Username: Noee Post Number: 625 Registered: 03-2002 Posted on Tuesday, May 13, 2003 - 10:19 pm:    I'd check to make sure the cable is connected to the valve on the water hose to the core. Mine was loose and would not close the valve all the way. What's really cool is that my heater cable now works great, but my vent cable turns on the heat! It would also help if you'd lose those white letter street tires...   Art Bitterman (Aardvark) New Member Username: Aardvark Post Number: 4 Registered: 05-2003 Posted on Wednesday, May 14, 2003 - 09:05 am:    Are you sure it's the heater? I get so much heat coming from the engine and gearbox, that I don't need a heater much in the winter (I'm in Georgia, which has pretty mild winters) But during the summer can get rather intense!   Brad Russell (Bradnc) Senior Member Username: Bradnc Post Number: 280 Registered: 03-2002 Posted on Thursday, May 15, 2003 - 10:00 am:    I think Max was telling me that if you put in some high quality heat and sound insulation that it helps out with that tremendously. Can you verify that heat is actually being pumped out of the vents?   Keith Armstrong (Keith) New Member Username: Keith Post Number: 2 Registered: 02-2003 Posted on Thursday, May 15, 2003 - 04:01 pm:    Don't want to be a smarty pants here....but my IIa doesn't have a "heater control valve" as such. There is what looks like a garden hose valve on the top rear of the head. Close that valve and coolant shouldn't circulate thru the heater core.   Thomas Dahbura (U352) Member Username: U352 Post Number: 111 Registered: 10-2002 Posted on Thursday, May 15, 2003 - 08:49 pm:    Two low blows. Whats wrong with the tires. I plan on making them white walled soon   Reed Cotton (Reedcotton) Member Username: Reedcotton Post Number: 104 Registered: 01-2003 Posted on Sunday, May 25, 2003 - 01:57 pm:    Keith- You beat me to the answer. Sometimes though, the rubber in the valve deteriorates and the valve won't completely shut no matter how tight its screwed down (bad idea anyway). But even with a bad valve shut, there should be less heat going to the heater. -Reed
