Default Thermostat Question

It takes about 10-15 minutes of driving before my car temp gauge reaches a little less than 9oclock. Is this normal? I don't have time to start my car and let it sit for that much time or else I would be late to school but I noticed I'm about halfway to school before my heater actually kicks in. Do I need to change my thermostat or what?

This was happening to me. I removed the thermostat and found it was mechanically stuck open. (clip was stuck to the coil). i released it and put it back in and everything's been good. Maybe that's what's happening to you. Use a new gasket on thermostat housing. Good luck

It takes at least a few minutes, but the warm-up rate also depends on the outside temperature, speed, and throttle you give it.

You don't need to wait for the engine to get to operating temp. before driving. Start the engine and give the tranny 30 seconds to build pressure and go.

M heater starts blowing warm air after about 2 minutes. That's when the temp treads 80+ *F. I have a 178* T-stat in it. At 98* it blows hot air.

Yeah it takes WAY longer than 2 minutes for my heater to blow hot air, I'll check the thermostat later. I need to order new fittings right now

My gauge (and they all read a little differently) comes to almost 8:00 at 130 F, and won't go past 9:00 until beyond 235 F, and it is not linear. I would agree also that no need to wait for warm up by gauge. Now warm up by feeling warm in truck is a different time issue. Engine will warm up faster under power than idle.

It is also correct to say if the thermostat is sticking it will take a long time to get heat. With no stat at all (which I tried), I would only get to 135 - 145 F water temp in summer, that would be less in winter.

So if you still don't get heat "soon enough" you might consider replacing $10 stat (which might be sticking) with either a 180 or 195F, don't use a 160 or you will have too little heat. You also want stat to have a vent device or drill a small hole in it, which allows coolant bubbles to pass.

Which fitting do I need to buy?
I'm looking at the m1-3 10mm x 1 fine thread with non-threaded lead for SAE and DIN flare. Can somebody send me a link of the correct ones from fedhill?
