Farmer Posted April 30, 2011 Report Share Posted April 30, 2011 Is the lower radiator hose suppose to be hot? My temp gauge is reading mid level, top hose is hot, heater hose to heater, both lines are hot, but lower hose is barely warm. Also on weber carb, once carb and engine get hot, you can screw the fuel/air mixture screw inward and the idle will rev up until the screw stops. I'm wanting to get to the meet in Vancouver. If I get there; maybe someone can help. Larry Quote Link to comment
datzenmike Posted April 30, 2011 Report Share Posted April 30, 2011 Hot water goes in the top comes out the bottom cool(er). The coolest water in the system will be in the lower rad hose. Quote Link to comment
Farmer Posted April 30, 2011 Author Report Share Posted April 30, 2011 I know that the direction of flow but its barely warm. Like room temp warm. I just afraid of break down. Quote Link to comment

HRH Posted May 1, 2011 Report Share Posted May 1, 2011 Spot check it with a infrared heat gun. The lower hose on my hardbody rarely gets hotter than 90 degrees. Enough so you can put your hand on it. An L that is running rich, and possibly a 160 thermostat will definitely have a cool hose on the bottom. Spot check the thermostat housing and upper and lower, then go over the radiator with the infrared. That will tell you a lot more. You can pick those up at harbor freight for 50 bucks or maybe less.

Farmer Posted May 1, 2011 Author Report Share Posted May 1, 2011 Thanks for the tips. Weber: turning mixture screw clock wise, is it richening or leaning fuel mixture? Im reading as much weber topics as i can find here on the site. Larry Quote Link to comment
