Thread: Coolant Leak

  1. #1

    Default Coolant Leak

    Hi I keep seeing little puddles of antifreeze underneath the left front bumper of my 01 surbuban. The overflow tank is on the otherside. Any idea where its coming from.

    My 98 silverado did the same thing. Small radiator leak for a month or so and then one day it really started leaking.

    Had to replace the radiator. But check your hose on that side first. Radiators aren't cheap and that could be an easy fix if its a hose or a clamp.

    I have a 99' tahoe that did the same thing and leaked in the same spot. I had a small crack in the radiator. i ended up having to replace it, the stock radiator was $199 but i went ahead and got the heavy duty one for $230 (includes the oil cooler) but I agree with TommyBoy, check for small issues first, i'd hate for you to replace the radiator and find out it wasnt the problem. Good luck!

    Pressure test the cooling system and see where the leak is and go from there

    Yes behind the driver side bumper in front of the wheel. I do't see any lines or part of the radiator over there.

    Hey Twiggy

    Where did you find a radiator with that price. I paid $299 for mine it was a 3 row with trans and engine oiler cooler though. Whats your part source? I might want to check that out.
