04 vw jetta overheating. vw glooged hose. vw temp problems. vw no coolant flow. She is back. sooo. now we have a over heating issue. gauges seems fine. tip. map sensor and thermostat and do the throttle body while your at it very gentle.
1. low coolant level. one of the primary reasons for engine overheating in jetta is a low level of coolant or antifreeze in the cooling system. coolant plays a critical role in regulating the engine’s temperature by dissipating heat. when the coolant level is low, there is not enough fluid to absorb and transfer heat away from the engine.

Hot = thermostat ok, cold = thermostat not ok. at that point, engage the vents at max hot, so that will circulate the coolant in all the circuit. next up, rev the engine to 1500 2000rpm, radiator fan should kick in. if the fan doesn't, it may be kaput, or the radiator temperature sensor (g83) could also be kaput. Driving while overheating can cause long term engine damage. 2. white smoke. if your jetta’s engine gets hot enough, the coolant will begin to boil over and manifest itself as steam coming up from under the hood. it does this to relieve the pressure on the cooling system before lasting damage can occur. 3.

This time we are breaking down the engine coolant temperature sensor, or ect. you may also see this part referred to as a c.t.s. (coolant temperature sensor). i have put so many ects on vws that it’s crazy. i really enjoyed doing this video. if you have a part you would like me do to a video on, shoot me an email to charles (at)humblemechanic. Replacing a coolant temperature sensor isn’t as simple as fixing it yourself with a video tutorial. below is how a technician will properly replace a temperature sensor: disconnect the battery after the vehicle and the engine are completely cooled down. remove plastic engine coverings. partially drain the cooling system, doing a.
