![]() Neither goes directly to the Cluster(dashboard) Gauge. I have looked at the wiring diagrams, and both circuits go to the ECU. There are two circuits to the Coolant-temperature-Sensor. It has saved my B4 in the winter due to pulverizing 'road bergs' that lurk in the roadway.Ĭluster gauge is glorified OverTemp Lamp. I will eventually have one on the wagon, but probably won't bother with the wife's B4 since I'm not sure how long we'll have it. I would not worry about the Odin plate and temperatures. They all start immediately in any conditions and come up to temperature fine. We have no problem with any of the cars in the winter. ![]() She tries to drive it hard, but I purposefully keep it detuned because she's a maniac already and I can't imagine her with any additional power. The wife's B4 is stock but for the Sprint 205's, it gets 44-46 mpg. I noticed no difference in economy with or without it. It had the stock bellypan on it but I removed it to do some work and have not put it back on. I changed the thermostat due to having to purge and flush the coolant to switch it back to G12. I drive it easier than the sedan, but more spirited than most people probably would. The wagon has Wett chips and is stock, it gets 48-50 mpg. I did not notice a change when I went from the stock belly pan to the Odin plate. I do not drive it easy since it's so much fun. My sedan is modified somewhat, it gets 47-49 mpg. All temperatures are measured on a Scangauge. The wife's B4 has no belly pan and stock 87° thermostat, the operating temperature will vary from 185° to 195° and its running 'evil green' coolant. My B4V has the stock plastic belly pan and a 95° thermostat, the operating temperature will vary from 193° to 212° and it's running G12 now. My B4 has an Odin skid plate and a 90° thermostat, the operating temperature will vary from 183° to 198° depending on the load and it's running G12. 60/40 is the highest strength of coolant to water ratio before the additional coolant no longer helps either the boil point or the freeze point. If you add extra G12 to the coolant to bring the glycol/water mix to 60% glycol, then the maximum boil temperature will be raised from the 50/50 level.Īccording to AutoZone, Canadian VWs were filled with 60/40 coolant so the block wont freeze in the winter. So IF you plan on hauling a roof-rack full of stuff, 4 passeners,and perhaps a 1500# trailer over some of the steeper roads (7-10% grades), then make sure you have extra coolant and water along. The Dashboard Temperature Gauge is a glorified yes / no lamp) Once the Cooling Fans hav reached their maximum velocity, and the cooling power of the radiator reaches its maximum, the coolant Temperature gauge would be increasing (however I have found by experiment, Its not a one-to-one relationship). The temperature will stay relatively constant as long as the cooling system is functioning properly. This is around 35-40% of the energy that is in the fuel, 60-65% gets converted to heat. The energy of the burning fuel (Chemical) converts to mechanical energy. If the Ambient temperature is really cold, then the coolant Thermostat will not even open! ( its rare but possible). The Thing to be aware of, is that the Jetta / Golf / Passat will adjust the Fan speed to increase cooling if it gets too hot, or will shut them off if it gets to cool. So, the Operating Temp is best at 195F/90C just as the Temp Gauge Shows at the Middle by the Dashboard.
