    i need some assistance on fixing the problem

  • merciergal72 May 29, 2009

    1200 is what the dealership is charging 500 at a radiator shop is it safe to use an aftermarket part

  • merciergal72 May 29, 2009

    thank you, very helpful now comes the fix..i am quoted $1200 dollars from the dealership for repair almost 1000 in labor alone. i realize this is an extensive repair taking out the dash and all but i also called a local radiator shop that can do the whole job for under 500. they use an aftermarket part that they claim is made by the same company that makes the ac delco. is this true, and is there anything i should be aware of if i take it to the radiator shop versus the dealership?

If the coolant is in the cab they did not cause the problem changing the manifold gasket. It sounds like the heater core has failed, which is under the dash.

Leaking, overheating --- *fixed* then puff of white smoke 1 week later


I'm not taking sides in this. So what I am going to say is more or less neutral.
There is a big possibility you damaged the head gasket when the engine overheated last week. The dealership would have no way of knowing this if it was not yet leaking into the engine when they replaced the water pump.
Once the water pump leak was fixed, the system would be running under normal pressure which could finish off the weak head gasket.
You can not see a damaged head gasket without removing the cylinder head. And you have two heads with two gaskets.
So, IF the head gasket is now blown there is a good chance they did not know it last week. It could also be a cracked cyl head or leaking intake manifold gasket. Or all of the above.

I have a 02 Chevy tahoe....it sounds like coolant rushing throughout the engine while sitting at an idle and about every 2 or 3 days I gotta add coolant its not much also the low coolant light comes on...


I would perform a coolant pressure test because these engines are known for leaking intake manifold gaskets.Check and see if your oil is starting to turn a creamy tan color.

Coolant leak 05 denali


I will assume as usual that it has the 5.7L engine. The common cause for a coolant leak in these truck are the intake manifold. It either leaks externally or internally or both this is a common problem with this engine. You have to replace the intake gaskets. This a fairly big job. First check your engine oil if the level has risen and if the oil smells like anti freeze or looks like a milkshake kinda foamy then the chances are good that your intake is leaking.If all else fails you will have to do a coolant pressure test and you will seee the leak probably.It could also be your cylinder head gaskets but the most likely cause is the intake gasket. $100.00 for the gasket kit and about 5-6 labour. Change your oil & filter before you start it after you replace the gaskets. Then if your leak goes away change your oil & filter again about a week later to ensure you get all the coolant out of the engine oil this is very harmfull to the bearings in the engine.

My chevy impala smells like the radiator liquid is burning and the check engine light came i put coolant in there and the check engine light went off but it came back on. it seems to be leaking coolant but...


Check the front passenger side carpet and make sure it is dry. If it is wet, the heater core up under the dash is leaking, which is why you smell it in the cab.

Strong coolant odor in cab of car Chevy Tahoe 2002


Honestly, if you are smelling coolant in your cab, 9 times out of 10 the culprit is the heater core or a lin in the cab going to the heater core. A coolant line going the the intake would come directly off of the radiator if I'm not mistaken, which is in the front of the truck... and further away from the cab. Instead of using a paper towel, smell the carpet. If you have pets don't let them near the carpet. Anti freez has a sweet taste but is VERY deadly.

It's possible that the heater core is on it's way out but not completely failed, or there could be a leak that only occurs under high pressure (like when your on the interstate).

I keep having to refill my coolant tank what do i need to do


There is a small hole under the extension behind where the pulley is mounted, most times barely visible. If you see any coolant there the pump seal is leaking. Many times it will show up better with the cap off, as internal pressure can sometimes push the seal against the shaft and temporarily stop the leak. If any coolant is found there,(sometimes it will run down the lower hose and appear like a bad hose or clamp) the pump needs to be changed. No, it is in no way related to a manifold gasket leak.
