Vdo 250f water temp sending unit 10 x 1mm.
Vw bug oil temp sensor location.
Ok guys i was installing a oil pressure gauge in my obd1 12v vr.
The little black sensor on the oil filter housing in the back the metal tip broke off which i believe is for oil temp but not sure.
My beetle has a stock 1600cc dual port engine with a stock 34pict 3 carburetor and pertonix ignitor.
This five minute installation could save your engine.
Simply replace your stock dipstick with this one attach one wire and the factory idiot light on your dash will flash and then light solid if your oil temp gets too high.
Dipstick oil temperature sender protect your engine.
As the engine is running a typical oil temp sensor is reading the temp of oil that s already cooled the engine oil that s run down from the head and oil that s squirted out of the bearings lands in the sump.
At 80 km hour the oil temperature drops to about 92c.
The oil from the heads is significantly hotter than oil that s come out of the crank bearings.
