I have a 1999 Ford Taurus that would not heat, took to shop they flushed the system, replaced the water pump and it ran hot after thet flushed the system took it back they flushed the system again and


Did you have red antifreeze prior to the flushing? Ford engines are generally aluminium and should be using blue antifreeze which is suitable for aluminium engine blocks! I think the antifreeze is reacting to the aluminium.....re flush and use blue!

Have a 2003 monty carlo ss. I have had to get system completely flushed 5 times keeps getting gunked up. It's only been six months and I have to get it flushed again.Service engine light also stays...


If you are talking about the coolant system there are a few things that cause them to get gunked up. I have found most of the time with the 3.8 liter and 3.4 liter motors that the intake gasket is leaking and allowing oil to mix with the antifreeze and I have also run across people mixing Dexcool and regular green antifreeze and that will cause the cooling system to gel up also.

My raidiator is jelled up twice now first time we flushed out and put new antifreaze and it was good for about a month then it happenmd again


If you flushed the radiator OFF of the vehicle, there could have been residue still in the engine that made it's way into the radiator when you put it back on. If you flushed it thoroughly on the car then the only expanations I can think of are 1: Bad head gasket leaking oil into the water system. The water will be grayish brown (brownish gray?) 2: Someone is sabotaging your ride. I hate the #2 option because I'm not a suspicious person and really don't want to believe it but ther is NO mechanical explanation that would cause your antifreeze to gel, that I'm aware of.

Need to drain coolant from 1998 Olds Intrigue. What is best way? (3800 Engine)


COOLANT CHANGEON THE RADIATOR (LOWER DRIVERS SIDE FACING THE MOTOR) THERE IS A PLASTIC LIKE PLUG THAT YOU TURN COUNTER CLOCKWISE ABOUT 3/4 OF A TURN, THEN YOU CAN PULL IT OUT ABOUT 1/2 AN INCH THIS WILL DRAIN THE RADIATOR, THEN YOU CAN PUSH THE PLUG BACK IN AND TURN IT UNTIL YOU FEEL IT LOCK BACK IN PLACE. REFILL RADIATOR WITH 3 PARTS COOLANT TO 1 PART WATER.
1998-'99 Intrigues equipped with the 3800 engine have a specific process for replacing antifreeze. It is somewhat of a lengthy process and you should refer to your owners manual for doing this. After you empty and flush your system with water (garden hose), only fill the system with green 50/50 antifreeze, NOT Dex-Cool. Avoid Dex-Cool. If you bring your Intrigue to a shop to get serviced, make sure and inform whoever doing repairs and/or leave a note (clearly visible) to NOT use Dex-Cool if they're doing any work pertaining to cooling system.

1998 Volkswagon jetta GL OBDII code P0117 (engine coolant temp LOW IMPUT) What is the fix? Installed new thermastate, Rad&engine flush, Replaced water pump about a year ago.


Comment from the FixYa Moderator Staff:

Regarding your PO0117 code, I would suggest to you to replace the Coolant Temperature Sensor. This is a rather common isue, either the sensor is bad, the wiring connection is compromised, or the coolant level is low. I woul dthink that the senor is the issue, however.

Thnaks or coming to FixYa for advice with your VW.

Location of crank sensor 1998 jetta 2.0


It's located near the cam gear on the front of the engine however, the crank sensor, to the right of the oil filter near the bell housing is the part notorious for going out on these cars, and causing a p0322 and/or p0341 code, and sometimes others as well To replace the crank sensor you have to: Support the motor with a floor jack. Remove the starter, 2 of the starter bolts connect to the motor mount. Remove the motor mount from the frame, very easy. Remove the oil filter. That will give you just enough room to get an allen wrench in to remove the bolt holding the sensor in.

I have a 2002 Volkswagon Jetta and just started to overheat when stuck in traffic, the gauge goes up to 240 and the overheat light goes on but drops to normal when traffic is moving again - any idea what...


Check
1)thermostat and also that the electric fan is kicking in when it gets above normal temp
2)blocked radiator
3)worn water pump (more so from electrolysis, ie not using the right antifreeze)

I have a 98 cavalier. it runs hot after engine is runnung for a while. the fan comes on and helps it a bit but not enough. and the air from the heater inside never gets warm , where do i start? thx


It sounds like you need to service your cooling system. The cooling system may need to be flushed out due to dirty from corrosion. A sign of no heat in the heater and the engine is hot is low on antifreeze in the system. Check the antifreeze level first and add water just to get around to buy the things you need to service the cooling system. Buy antifreeze and a thermostat, drain the old antifreeze and replace the thermostat. Add new antifreeze with a 50/50 mix solution water/antifreeze. Too much antifreeze will gel and the cooling system will still run hot and to much water will boil over. Good luck. Keep me posted be glad to help.

2000 Jetta is Leaking antifreeze and smoking


I think you mean you saw water vapor (some call it steam) not smoke.

You probably have a hose leaking (badly). If it's not a hose, your water pump shaft seal is probably kaput.
