I have a 2000 vwb with a 2.0 engine, it keeps overheating. I have replaced the radiator flange and it overheated and melted that. Anyone know if there is a fan delay or relay switch?

98 deville 32 valve North Star OVERHEATS after 33 miles of drive ?? does not overheat in town overheats out on highway and after slowing down- fans dont cool motor unless stop engine ,have changed radiator...


The most common overheating problem with the Northstar engine is a blocked purge line(small hose).The purge line is designed to purge air out of the cooling system.
There is a small diameter hose coming from near the top of the coolant tank (not the cap) ,this is the purge line.
With the engine idling,pull the purge line from the tank,if there is no coolant flow from this small hose,it is blocked and this will cause overheating.
If the hose is clear, check for blockage at the nipple on the tank.Or trace the hose back until you find the blockage.
The hose goes in to the engine to a crossover and comes out the other side close to the thermostat housing,the blockage may be there.
Also note that the cooling fans don't come on until the coolant temperature hits around 225 degrees.
During normal highway driving the fans will very rarely come on(if at all) due to constant air flow through the radiator.They will only usually come on in heavy traffic conditions on a hot day.
But......if you have the Air Con switched on, the fans will run all of the time.

2000 Plymouth Voyager Overheating


The radiator cooling fan relay has most likely failed. It is underneath the air cleaner on the frame rail just behind the radiator. NO cooling fan = overheating. This is the first thing i would look at. Best way to tell is when the van gets hot see if the cooling fan is on. You will hear it running if it is coming on. It will set a code for the cooling fan relay also.
