#2440 of 2540 Antifreeze leaks from bottom of engine just as fast as I pour into radiator
May 07, 2012 (6:59 am)
2002 Buick rendezvous getting hot coolant level reading changed the water pump and thermostat after adding coolant in radiator all the coolant drained straight from bottom of engine fast as I poured the antifreeze in it drained out.
Here is what I have experienced:
First, I saw that at the water pump coolant was spitting out so I changed that then after test drive after changing the water pump still got high coolant temp reading now I saw that coolant leaked from the thermostat housing area so I changed that after putting everything back together doing another test drive return home and adding a little more antifreeze in the radiator all the coolant began to leak from the very bottom of the engine just as fast as I poured it into the radiator. What do I do now, What is the problem? Please help

This is probably not the same thing but early on with my '03 RDV I was seeing a lot of coolant loss. I'd fill the reservoir to the line and a month or so later it was down, near empty. I did that for about 4 - 5 months, refill, refill and refill again until, I guess, all the original OEM fluid was gone. I used aftermarket fluid, the kind that's recommended as a replacement. Since then, no problems.
This car is the oddest one I've ever owned. Crazy problems that never have happened in any other car I've owned. The car I had before this one was a Mercury Villager - 122,000 miles on it and except for a faulty EGR valve, zero problems. Now this . . .

You are right in what you did getting the OEM grade, I'm an old timer and now work in at O'Reilly Auto part time. I was amazed at the different requirements car to car manufacturer. This includes battiies , brake fuild, trans and antifreeze, so you need to ck your manual for the required fluilds. If it says universal your probably safe.

I owned two buicks previous to my 2004 Rendevous and this car made up for all the problems I never had before. Next time I will not relie on the brand, will ck consumer report. Buicl has slipped on these cars.

I just checked the fluid in my car. Its full. Last time I filled it was about 1 1/2 years ago. Before that I had to add fluid about every 6 - 8 months. I don't recall the brand I used but its orange, not green color. As I recall, I bought it at KMart or Walmart. Its a direct replacement for the OEM stuff. Perhaps the name is "Nu-Temp" or something like that. Zero problems since I put it in. Now the coolant is 100% the replacement fluid. No OEM stuff in the system.

Well, it sounds like you somehow solved your problem. You might want to check out all the various complaints about the GM antifreeze they put in the 02' RDZ. I don't know if they are still using it or not but after doing the research, I drained all of it out of mine and went to 5 year Prestone. I have an 05' which at the time had only 40,000 miles and the OEM antifreeze in it.

Draining any antifreeze every couple of years is good, lifetime label or not.
As for taking out DexCool from 02 and replacing with Prestone Mixes with All Colors antifreeze: they are the same. Look at the label and look at the MDS info on the Prestone website. Other than a coloring, it appears to me they are the same.

Might be bad wiring to the wheel speed sensor. Could be in the connector.
