thermostat & fan settings would help avoid that. If you got into the red at the end of an autocross run, using a lower temp. to start also can help with spot heating issues from sudden increase in power (heat), giving the system time to catch up as coolant circulates. Normal cooling system isn't sized for constant high power & heat production, but with more range to absorb temp. A few have run without ANY cooling system, concrete in the water jacket to solidify the block for more strength & it just has a long cooling time between runs. First step of that type is having a water tank that's adequate to cool a single pass, it can cool off and/or have water replaced after the run. Think of a dragster that doesn't even run a radiator. on a performance engine is a way to give the system additional "range" to absorb temporary spikes in heat production.ĭoesn't help if you're running a constant high speed/load and the cooling system just can't keep up, but in many cases the higher heat load is temporary so the system has a chance to dissipate the extra heat later. So what are the normal operating temps for the Focus supposed to be? Where's hot or overheating territory? And what sort of things should I start looking into as a means of troubleshooting if the car is indeed supposed to be running cooler and the fan should be kicking in when it isn't? Otherwise, I have not noticed the fans running while driving around, but it could also be that I simply didn't notice. The only time I've heard the fan cycle for sure is with use of the A/C, and to me it's pretty clear when it does come on. The temperature never really read below 200.Īnother thing I haven't noticed is the fan coming on, so that's what got me wondering if maybe the Focus just runs hotter than my old car (which liked to hang around 185 deg F), and maybe I just didn't hit the too hot territory yet. It didn't vary much whether I was moving, stationary, or even on the highway. I noticed the temperature hanging around in the 200-220 range while driving around, and sometimes a bit higher than that.
NORMAL COOLANT TEMP BLUETOOTH
I have an OBD2 Bluetooth dongle and the Torque app, and used that a few days ago while out doing some normal driving just to see what I could see. The car is a stock 03 ZX3, manual, and I just picked it up 2 weeks ago, so I'm still learning and feeling out things. I just wanted to ask about the coolant system operation on the 1st gen Focus to see if I may have an issue or not. It sounds like the winter lips should stay on until the coolant temperature hits 200F. KenJapan P PA Prius Registered Joined 216 Posts Discussion Starter 4 Thanks, this is helpful. Fortuantely, on all 3 of my Hemi's, I've never had this problem.Hey, folks. We see the typical coolant temperature is about 88C (190F). Then for sure you'll need the bleed hose/funnel setup which, IMO would be a little more work. It comes from the factory way over tightened, IMO, and some folks can't even get the plug out and end up stripping it. Then put the plug back in using a little teflon tape or Permatex 2 (non-hardening) sealant and tighten the plug just enough so it won't leak. pipe plug from the water pump (near the thermostat housing) and fill until coolant begins to come out of the hole. Also, I only use Mopar HOAT coolant and distilled water.nothing else.īleeding the air out of the system is really quite easy. When everything was drained, this is when I changed the thermostat to a 190* one. The only thing that's even slightly difficult is pulling the splash cover (the one that screws to the front fascia) so you can easily get to the plastic radiator drain valve. I also pulled the overflow tank and emptied/cleaned it too. I'd like to see it a bit lower, personally.Īnyone have any disagreement with the above?Īlso, any thoughts on that coolant color - gold vs pink?Ĭlick to expand.When I did my SRT8 I was going to do other work too, so I did a complete change.removed the block drain plugs as well as the radiator. Temperature, the wax expands enough to overcome the closing spring and water pump pressure, which When heated coolant reaches a predetermined The thermostat is operated by a wax filled container (pellet) which is sealed. This temperature the coolant temperature is controlled by the radiator, fan, and ambient temperature, not the thermostat. Not restrict flow to the radiator as temperature of the coolant rises in hot weather to around 104° C (220° F). The thermostat also will automatically reach wide open so it will Provide the fastest warm up possible by preventing leakage through it and to guarantee a minimum engine operating The engine cooling thermostat is a wax pellet driven, reverse poppet choke type.
