Engine dies at 150 degrees.

What faults codes are showing on a test of the electronic engine control module?

Do you have a check engine light on ? If so Get codes first for a direction. Sounds like temp sender or coolant component is faulty.

DO A TUNE UP.CHANGE SPARK PLUGS AND WIRES.CHANGE AIR FILTER AND FUEL FILTER CLEAN FUEL INJECTORS WITH A CAN OF SEAFOAM. HAVE TRANSMISSION FLUID AND FILTER CHANGED. DOING A TUNE UP WILL TELL YOU IF YOU HAVE MINOR ENGINE PROBLEMS OR MAJOR ENGINE PROBLEMS. IF YOU BOUGHT CAR THAT A LEMON YOU CAN TAKE BACK IT. AFTER SO MANY DAYS.

Heed of antifreeze coolant temperature!!!
First time you might check the thermostat operating.
The thermostat location for VW Golf 1.6 is inside of coolant thermostat housing placed on back side of the cylinder head. See pictures below.
Thermostat checking:
1. Cold engine. Start up the engine and watch of the water temp indicator. After first value 60 Celsius Degree you still warm up the engine until the lifter (pointer) reach 80 C deg. (second mark after 60 C deg.). At this time you let engine running at idle speed and check with your hand the thermostat plastic housing and hose temperature in bottom left side of the engine. Heed of alternator driving belt and ventilator fan !!!
2. If the thermostat is good the hose must be cold until the water temp indicator reach almost 90 C deg.
3. The thermostat opening temperature is 87 C deg.
4. If the hose is already warm the thermostat is out of order.

Important note: Always replace the thermostat round seal, position 6 in the above picture.

Check the engine thermostat!

Thermostat checking:
1. Cold engine. Start up the engine and watch of the water temp indicator. After first value 140 degrees F you still warm up the engine until the lifter (pointer) reach 175 deg. F (second mark after 140 deg. F). At this time you let engine running at idle speed and check with your hand the thermostat plastic housing and hose temperature in bottom left side of the engine. Heed of alternator driving belt and ventilator fan !!!
2. If the thermostat is good the hose must be cold until the water temp indicator reach almost 195 deg. F.
3. The thermostat opening temperature is 188 deg. F.
4. If the hose is already warm the thermostat is out of order.

Replace the thermostat if necessary!

these have a problem with the overhead cams, one or more of the bolts break which restricts the oil flow to the lifters.

I recently had a similar problem. I got my car scanned and needed a new catalytic converter. If its already starting to spit and sputter, you probably have 3-6 months to get this done. Mine plugged up one day, and just flat out would not drive anymore. This cost of this repair was about (i recommend changing the spark plugs and wires also) $675....pretty costly. could get a lot more expensive the longer u let it go. Does your jetta run cold, in cold temp? (between 25-40 degrees) if so the thermostat probably took out the converter.

generally it's in the range of 200 -220 degrees F same as the transmission. it can run upto 240 before it startes to brakedown.please rate this
