I WOULD CHECK BOTH RADIATOR HOSES TO MAKE SURE THEY ARE HOT. THERMOSTAT COULD BE STICKING SLIGHTLY CLOSED.CHECK COOLANT LEVEL MAKE SURE COOLANT NOT LOW.IF COOLING NOT BOILING OUT OF THE EXPANSION TANK. I WOULD HAVE CAR HOOKED UP TO A DIAGNOTIC SCANNER AND CHECK COOLANT TEMPERATURE SEE IF TEMP. OVER 230 DEGREES IF SO RADIATOR COOLING FANS NOT WORKING.COOLANT THERMO SWITCH BAD BOTH FANS SHOULD BE RUNNING AT LOW SPEED.IF ALL LOOKS GOOD YOU COULD HAVE FAULTY LOW COOLANT SENSOR IN EXPANSION TANK.MAKE SURE COOLANT IS IN THE EXPANSION TANK BECAUSE COOLANT LEVEL COULD BE LOW.ADD COOLANT IN THE EXPANSION TANK UNTIL YOU AT MAX LEVEL LINE ON THE EXPANSION TANK.DONT OVER FILL THE EXPANSION KEEP ADDING COOLANT UNTIL COOLANT LEVEL STAYS AT THE MAX LEVEL LINE ON THE EXPANSION TANK.

WHAT KIND OF ANTI FREEZE


2000 was around the year of the switch. if it has green coolant you can use anything off the shelf from a parts store. If its pink colored then its a special formula made by Vw and Audi called G12. Its also the same as the new toyota pink coolant. DO NOT USE PRESTONE MIX WITH ANY COLOR ANTIFREEZE IN THIS VEHICLE.

Need to put engine coolant in a 1999 Chrysler 300m. The reservoir says it takes a special kind of coolant. What kind? Can I use Prestone 50/50


whar steps do I take after draing the coolant from the radiator. I have a 1999 chysler 300m. Should the engine be running while replacing the coolant. This car does not have a radiator cap to remove. Do I just add the coolant in the resivor while the engine is running?

Type of coolant required


They have special coolant now that is accepted by either color (green or orange) I believe Nissan uses Orange, just make sure you dont mix the two as it will gel up on you

1996 vw jetta vr6 keeps overheating,


Get another boyfriend! "Just kidding"! ok, this is what I mean about "leaving it to the experts". #1 Make sure there is enough coolant, Check for leaks. Install a coolant pressure tester and check for leaks. Fix whats leaking. #2 Make sure coolant fans are coming on, and specifically at 220 degrees. If not, check fuses. Jump the coolant fan to make sure it comes on. if it does, then you may have a bad relay, make sure relay is commanded on. At this point , you may need a wire schematic for the coolant fans and related parts.

There are two coolant temp sensors. One by the oil filler tube and one near the bottom radiator hose near the radiator.
When you flushed the coolant did you replace with VW rated G12 coloant? Very Important! - You can't use over the counter coolant - it'll cause sludge in your system. You have to use G12...

Hope this helps!

My son at college has a 97 Jetta and recently the coolant warning light on the dash came on. The engine temperature light did not come on. A mechanic said he needs a new radiator. How can we test the speed...


First of all tell your mechanic to relax and breathe in a bit... If the radiator needed changing the temperature of the engine would either go up and overheat or it would vary ALOT from cold to hot to cold to hot, etc. when the car is running. In 99% of the cases where the coolant warning light comes on, it just means that there is not enough prestone/coolant in the reserve/catch tank under the hood. On those models the said tank should look like a big white plastic ball with colored water in it. If it's empty, don't look any furter you just found the problem. Put some coolant in and check from time to time to be sure there actually is no leak in the system, cause even if there is no leak, there is an overflow system that shoots some out when the pressure is too high, so you will see the coolant level drop without having a leak. Just to be safe, have you son bring a gallon of tap water with him in case, as it will cost less than coolant if it leaks all over the place all the time, and it will do the same job as coolant if the ambient outside temperature is not under freezig point. Prestone/coolant is basically just ordinary water with a special type of sugar added into it to prevent it from freezing in the cold.
