Car must use red coolant or yellow generic designed for newer than 1995 vehicles. Why you wonder - Red is designed for 272 Degees of total fluid heat and since newer vehicles are Aluminum Motors / Cylinder heads it is required to have a Red / Yellow anti - freeze coolant mix to carry - transfer heat out to radiator to be cooled by wind or Temp sensor turning on radiator fans . The older Green coolant is only good to 230 degrees before boiling over . This green in older engines worked because Iron / Steel engine blocks - cylinder heads Absorbed Large amounts of Heat . 1995 and Newer Aluminum does not absorb heat and will Warp Block - Heads if not kept cool ergo milky looking Oil - Coolant . Be sure to get cocentration to 50% REd or Yellow Coolant to - 50%% Water , this also helps fight heat and will give you good winter proction at cold temps.

Change the thermostat and the coolat resevoir cap.These are the 2 main things for overheating problems. The thermostat sticks and the cap will let coolant escape from the tank, after a couple of trips the engine overheats. Also make sure your cooling fans are coming on. Physically pull the relays and all fuses, as the do lose contact.

DID YOU BLEED THE COOLING SYSTEM.THIS VECHICLE WHEN YOU REMOVE MOST OF THE COOLANT TO REPLACE WATER PUMP OR RADIATOR AND THERMOSTAT YOU HAVE TO BLEED OUT THE AIR TO GET COOLANT TO CIRCULATE PROPERLY. TO BLEED COOLANT SYSTEM WITH ENGINE COOL LOCATE BLEEDER SCREW AT WATER PUMP BY HOSE OPEN BLEEDER SCREW A LITTLE TO LET SOME AIR OUT WHILE YOU.POUR ANTIFREEZE IN RADIATOR.WHEN RADIATOR COOLANT LEVEL STOP DROPPING CLOSE BLEEDER SCREW AT WATER PUMP BYPASS HOSE.START ENGINE LET IDLE UNTIL GET WARM AND COOLANT DROPS IN RADIATOR ADD MORE COOLANT.WHEN COOLANT START RISING AT RADIATOR.PUT CAP ON RADIATOR LET VECHICLE IDLE A LITTLE AT A TIME.UNTIL THERMOSTAT OPENS THEN YOU CAN WAIT A LITTLE WHILE TAKE A LARGE RAG OVER RADIATOR CAP OPEN A LITTLE YOU WILL HEAR AIR STEAM HISS THROUGH CAP BUT DONT OPEN ALL THE WAY.WHEN HISSING STOP SLOWLY OPEN RADIATOR CAP A LITTLE AT A TIME SO YOU WONT GET SCALDED.YOU CRANK ENGINE UP A LITTLE STOP WAIT A WHILE BEFORE OPEN RADIATOR CAP.KEEP DOING THIS PROCEDURE UNTIL RADIATOR COOLANT STOP DROPPING.WHEN COOLANT STOP DROPPING.BLEEDING COOLANT SYSTEM COMPLETE.IF VECHICLE KEEP OVER HEATING CHECK OIL CRANK CASE LOOK LIKE MILK SHAKE YOU HAVE A BLOWN HEAD GASKET.
