2000 Chevrolet Venture engine problems

ENGINE

In January 2022, I noticed white smoke coming from the engine and a mechanic said it was the water pump that needed to be replaced, so I have it replaced. Recently, I noticed the same white smoke coming from the engine and took it back to the same mechanic who installed the water pump. The mechanic said it was the intake manifold that caused the white smoke. I decided to take it to another mechanic to see if the first diagnosis was correct and that mechanic confirmed the first mechanic's diagnosis and my previous experience with another GM vehicle (1997 Vhevy Lumina) that had the exact same problem: water pump went out and intake manifold also started to fail until the Lumina's engine was fried.

WE OWN A 2000 CHEVY VENTURE THAT WE BOUGHT USED ABOUT 4 YEARS AGO. WHEN WE BOUGHT IT, THE BUTTON FOR THE DOORS TO OPEN AUTOMATICALLY DIDN'T WORK AS WELL AS THE GAS GAUGE. SINCE, WE HAVE REPLACED THE HEADS, THE WATER PUMP, RACK AND PINION, WHEEL HUB, TIE ROD END, AS WELL AS REPLACING THE HEAD LIGHTS EVERY COUPLE MONTHS AND NOW HAVING PROBLEMS WITH THE BRAKE LIGHTS.WHEN WE HAD THE HEADS REPLACED, THEY FLUSHED THE RADIATOR AND WE ARE STILL HAVING PROBLEMS WITH THE LOW COOLANT LIGHT COMING ON AND THE FLUID LOOKING CLOUDY. THEY TOLD US THAT THE CLOUDINESS SOMETIMES HAPPENS, BUT STILL DOESN'T EXPLAIN THE LIGHT COMING ON SAYING ITS LOW!!! WE WERE ALSO NOTIFIED THAT THE ABS BOX IS BAD AND NEEDS REPLACED...ALSO, SOMETIMES THERE IS WATER THAT LEAKS FROM THE WEATHER GAUGE OR THE TOP OF THE WINDSHIELD. ALSO THE TRACTION SYSTEM LIGHT COMES ON AND ACTUALLY SHUTS THE SYSTEM OFF WHEN YOU TURN THE VAN ON, THIS MAYBE DUE TO THE BAD ABS BOX BUT HAS BEEN DOING THIS LONGER THEN THE ABS LIGHT HAS BEEN ON. THERE IS ALSO RUST ALONG THE VAN BELOW THE SLIDING DOORS. THE LOCKS ALSO SOMETIMES STICK WHEN USING THE KEYPAD OR THE ELECTRICAL LOCK BUTTON INSIDE THE VAN. WE CAN'T WAIT TO GET RID OF THIS VAN! JUST HOPE WE HAVE BETTER LUCK WITH OUR NEXT VEHICLE.

ENGINE AND ENGINE COOLING:ENGINE

LAST WINTER I LEFT MY 2000 CHEVROLET VENTURE VAN (WITH A 3.4 LITER V6 ENGINE) IDLING FOR ABOUT 10-15 MINUTES WHILE I WORKED OUTSIDE IT. WHEN I GOT BACK INSIDE, THE HEAT GAUGE WAS ABOUT 3/4 THE WAY TO HOT, AND NEITHER OF THE (2) ELECTRIC RADIATOR COOLING FANS WERE RUNNING. THE ENGINE RAN COOL FOR NORMAL UNCONJESTED TRAFFIC AFTER THIS. IN MID SUMMER THE HEAT GAUGE AGAIN WENT 3/4 HOT WHILE I WAS IN SLOW MOVING STOP-AND-GO TRAFFIC. TO PREVENT HEAT DAMAGE, I RAN THE HEATER FULL BLAST IN MID 80'S WEATHER; -NO FUN! I TROUBLESHOOT THE RADIATOR FANS CONTROL SYSTEM AND FOUND THAT THE PCM (POWER-TRAIN CONTROL MODULE; (COMPUTER)) WASN'T WORKING PROPERLY. I REPLACED THE PCM MYSELF WITH AN AFTER-MARKET, REFLASHED (REPROGRAMMED WITH GM UP-TO-DATE SOFTWARE) UNIT, BUT I COULDN'T GET THE PCM TO DO ITS 'CRANKSHAFT VARIATION RELEARN PROCEDURE' WITH MY EQUIPMENT, SO I TOOK THE VAN TO MY GM DEALERSHIP TO HAVE IT DONE, AND ALSO TO HAVE THE COOLING FANS TESTED. MY DEALERSHIP TESTED THE FANS AND FOUND THEY NOW WORKED, FINISHED THE PCM WORK, BUT THEY ALSO SAID THAT IT OVERHEATED AND BLEW COOLANT RIGHT OUT OF THE RESERVOIR; THEY DIAGNOSED IT WITH BLOWN HEAD GASKETS ON BOTH FRONT AND REAR PARTS. (IT DOESN'T SOUND BLOWN, HAVE COOLANT IN THE OIL, OR PUT EXHAUST IN THE COOLANT THAT I CAN SEE.) THEY QUOTED $1147.50 LABOR & $390. PARTS, & WHATEVER IT COST FOR A MACHINE SHOP TO CORRECT ANY HEAD WARPAGE, TO CORRECT THE PROBLEM. THEY ALSO ADVISED MY WIFE (WHO BROUGHT IN THE VAN), THAT THE VAN SHOULD NOT BE DRIVEN UNTIL THE HEAD GASKET PROBLEM IS FIXED. I HAVE TALKED WITH SEVERAL PEOPLE WHO TOLD ME THAT MOST EVERYONE WHO HAD THIS 3.4 LITER GM ENGINE HAS HAD TO HAVE THE HEAD GASKET REPLACED. ONE PERSON SAID THAT THEY THOUGHT THE GOVERNMENT SHOULD DO SOMETHING SINCE THE PROBLEM APPEARS TO BE SO WIDE SPREAD. I SUSPECT THAT THE PCM FAILING TO TURN ON THE COOLING FANS WAS WHAT CAUSED THIS HEAD GASKET FAILURE IN MY CASE. DO YOU HAVE OTHER PEOPLE REPORTING HEAD GASKET PROBLEMS?

WAS LOOSING COOLANT A MONTH OUT OF WARR.(LESS THAN 36K MILES IN 2003) DEALER REPLACED HEAD GASKET (SAME ON A '97 VENTURE I HAD) AND SQUEAKED IT UNDER WARR. NOW 5 YEARS LATER AT 63K MILE, THE SAME HEAD GASKET, SAME SPOT. DEALER SAID THAT THIS IS COMMON AND REPLACE THEM ALL THE TIME WITH THESE ENGINES BUT NO RECALL AT ALL.

ENGINE AND ENGINE COOLING

MATERIAL USED FOR HEAD GASKET AND EXHAUST MANIFOLD GASKET WERE MADE FROM MATERIAL WHICH DETERIORATED WHEN EXPOSED TO COOLANT. MANUFACTURER DEVELOPED NEW GASKET FROM ALUMINUM TO REPLACE, BUT NO RECALL WAS EVER ISSUED TO ACKNOWLEDGE THE PROBLEM. THIS HAS COST ME APPROXIMATELY $2500 IN REPAIRS, AND COULD HAVE RESULTED IN MAJOR ENGINE DAMAGE. THE DEALER SERVICE CENTER SEEMED TO BE WELL AWARE OF THE ISSUE, AS THEY ACTED LIKE THIS WASN'T THE FIRST ONE THEY HAD SEEN. THE FIRST REPAIR I HAD WAS FOR THE EXHAUST MANIFOLD GASKET, AND IT CAME TO $1300. LESS THAN 4 MONTHS AND 5000 MILES LATER, IT WAS BACK IN THE GARAGE WITH A DEFECTIVE HEAD GASKET. DEALER WAS KIND ENOUGH TO DISCOUNT THE REPAIR, BUT STILL CAME TO ANOTHER $1300. THIS WAS ON A VEHICLE THAT ONLY HAS 63000 MILES ON IT.

I HAVE GOTTEN THE SAME PROBLEM FIXED ON MY CHEVY VENTURE VAN (2000) THIS WILL BE THE THIRD TIME...THE INTAKE GASKET KEEPS BLOWING OUT...I WOULD HOPE IF ANY OTHER GM VEHICLE WITH THIS SAME PROBLEM WOULD COME FORWARD SO THERE CAN BE A RECALL ON THIS, SO WE CAN GET IT FIXED...TRUST ME IT IS NOT A "CHEAP" FIX AT ALL. THIS HAS BEEN FIXED WITHIN THE LAST 4 YEARS...3 TIMES...THE CAR STARTS LEAKING ANTIFREEZE, AND OVER HEATING THE VEHICLE.

ENGINE AND ENGINE COOLING:ENGINE

I HAD MY RADIATOR FLUSHED AND WAS TOLD THAT THERE SEEMED TO HAVE OIL IN MY COOLANT. I WAS TOLD BY OUR MECHANIC THAT THE HEAD GASKET HAD STARTED TO DISINTEGRATE, WHICH WAS CAUSING THE COOLANT TO LEAK INTO THE OIL. HE SAID THIS WAS A COMMON PROBLEM WITH DEXCOOL WHICH IS THE RECOMMENDED COOLANT TO BE USED IN OUR VAN. IF GM RECOMMENDS THAT THIS COOLANT BE USED, THEN THEY SHOULD HAVE TO PAY FOR THE REPAIRS. WHICH IS GOING TO COST US ABOUT $800 OR MORE IF OUR ENGINE BLOWS. WHEN WE FINALLY DO GET THE PROBLEM FIXED WE WILL NOT BE PUTTING THE RED DEXCOOL BACK IN IT, WE ARE SWITCHING TO THE GREEN, IT WAS RECOMMENDED BY OUR MECHANIC. WE CAN'T AFFORD TO FIX THIS PROBLEM RIGHT NOW WE HAVE TO WAIT FOR TAX REFUNDS, BECAUSE MY HUSBAND IS A DISABLED VET AND WE ARE ON A LIMITED INCOME.. SHAME ON GM FOR TAKING ADVANTAGE OF THEIR CONSUMERS LIKE THIS, AND I CAN SEE FROM ALL THE COMPLAINTS LISTED HERE THEY HAVE KNOWN ABOUT THE PROBLEM FOR QUITE SOME TIME.

NOTICED COOLANT LEAKING BROUGHT INTO MY MECHANIC HE DIAGNOSED " REPLACE INTAKE MANIFOLD GASKETS", BROUGHT VAN TO CHEVY TO SEE IF PERHAPS A RECALL BECAUSE I WAS TOLD BY MECHANIC THAT THIS PROBLEM IS COMMON WITH THIS ENGINE, BUT I WAS TOLD NO RECALL AND THEY ARE UNAWARE OF A PROBLEM WITH THIS ENGINE. SO I PAID $1,265 TO CHEVY TO REPAIR THEIR DEFECT ON A 2000 CHEVY VENTURE WITH JUST UNDER 25K MILES. AND THEY WONDER WHY PEOPLE ARE BUYING FOREIGN MADE CARS!!!!!

I NOTICED RED FLUID ON ONE OF THE LINES BELOW IN THE AREA OF THE COOLANT RESERVOIR. I DO HAVE DEXCOOL IN THE SYSTEM. I HAVE NOT DIAGNOSED THE PROBLEM AS TO WHERE THE COOLANT IS LEAKING FROM BUT I NOTICE THE RESERVOIR GETS LOW PERIODICALLY. I FEAR IT IS LEAKING FROM THE GASKET BUT NOT SURE YET. I HAVE NOTHING BUT PROBLEMS WITH THIS VEHICLE. I HAVE HAD TO SPEND $600-$1000 EVERY YEAR WHICH A COUPLE OF THE REPAIRS GM TOOK CARE OF AFTER REAMING THEM OUT. THEIR PRODUCT IS TERRIBLE AND I WILL NEVER BUY ANOTHER GM AGAIN.

ENGINE AND ENGINE COOLING

I HAVE A CHEVY VENTURE 2000. FOR THE LAST 6 MONTHS I HAVE HAD OIL SPOTS ON THE GROUND IN THE GARAGE, AND HAVE HAD TO KEEP FILLING UP THE COOLANT RESEVOIR TANK FOR A FEW WEEKS NOW. I HAD THE CAR CHECKED AT THE DEALER FOR THE OIL SPOTS AFTER HAVING THEM DO AN OIL CHANGE MONTHS AGO. THEY TOLD ME NOT TO WORRY ABOUT THAT SMALL AMOUNT OF OIL. HOWEVER WHEN I TOOK IT IN TO GET CHECKED WHY I WAS HAVING TO ADD COOLANT THEY FOUND THAT THE INTAKE MANIFOLD GASKET WAS LEAKING. IT COST ME $600.00 TO HAVE THIS REPAIRED. MY VAN HAS 86K MILES ON IT. IT HAS HAD THE GASKET REPLACED TWICE NOW. I HAVE RESEARCHED INFO FOR THIS PROBLEM AND HAVE FOUND MANY OTHER VEHICLE OWNERS OF THE 3.1L AND 3.4L MOTORS IN GM'S HAVING THE SAME PROBLEM. WHY DOES THIS CONTINUE TO BE A PROBLEM? THIS HAS TO BE DAMAGING THE ENGINE HAVING COOLANT BEING ABLE TO LEAK INTO IT. THE SERVICE STATION I WENT TO DOES SEVERAL OF THESE A MONTH ON 1998 TO 2001 MODELS WITH THESE ENGINES. THEY TOLD ME THAT THERE IS A FLAW WITH EITHER THE GASKET OR THE DEX COOL THAT CORRODES THE GASKET.

AT APPROXIMATELY 47,000 MILES THERE WAS DETERMINED TO BE A CONSUMPTION OF COOLANT, WITH NO LEAKS OUTSIDE OF THE ENGINE. THERE WAS THEN A LEAK THAT STARTED OUTSIDE OF THE ENGINE A FEW HUNDRED MILES LATER. VEHICLE WAS TAKEN TO DEALER FOR REPAIR ($800) OF THE INTAKE MANIFOLD GASKET. UPON RESEARCH ON THE INTERNET IT WAS DETERMINED THAT THIS FAILURE IS VERY COMMON TO THE GM V6 ENGINES (WHICH THE SERVICE MANAGER CONFIRMED). THIS NEEDS TO BE A RECALL!! GM IS AWARE OF THIS WITH TECHNICAL SERVICE BULLETIN 03-06-01-010.

I'M WRITING YOU THIS LETTER SINCE GM HAS REFUSED TO ACKNOWLEDGE THEY HAVE A FACTORY DEFECT IN THE INTAKE MANIFOLD GASKET AND BOLTS OF MAY OF THEIR GM VEHICLES.: TO INCLUDE MY 2000 CHEV VENTURE. RECENTLY WHILE ON A LONG TRIP OVER THE HOLIDAYS I NOTICED THE LOW COOLANT LIGHT HAD ILLUMINATED AND DISCOVERED OUR COOLANT WAS LEAKING. I TOOK IT TO THE SHOP TODAY AND IT COST ME $895 FOR THE REPAIR...NOT BAD COMPARED TO SOME BUT STILL A COST ONE WOULDN'T EXPECT TO PAY ON A CAR ONLY 3.5 YEARS OLD AND 70K MILES. MY WIFE AND I HAVE DONE SOME EXTENSIVE RESEARCH AND FOUND THIS SEEMS TO BE A SIGNIFICANT PROBLEM WITH GM CARS BUT YET THERE IS NO RECALL FOR THE PROBLEM. THE RESULT OF THESE GASKET FAILURES IS CLEARLY A DESIGN FLAW AND WE'VE N DOCUMENTATION WHERE YOUR COMPANY IS PAYING FOR OTHER MODELS MANIFOLD REPAIR COST. LOOKING OVER THIS SITE AND OTHERS DEDICATED TO THIS PROBLEM I'VE FOUND NUMEROUS OTHER STORIES SIMILAR AND MANY EVEN WORSE. I FIND IT HARD TO BELIEVE GM IS NOT STEPPING UP TO FIX THE COST OF THESE REPAIRS....THEY WILL LOSE MY BUSINESS.

GM KNOWS OF THIS MANFACTURER DEFECT BUT FAILS TO ACT IN REPAIRING THIS PROBLEM. THIS IS A SERIOUS SAFETY ISSUE AND CAN CAUSE MAJOR ENGINE PROBLEMS IF NOT REPAIRED IF OTHER DAMAGE HAS NOT ALREADY OCCURED DUE THIS MANUFACTURER DEFECT.
