if the leak is at the thermostat housing, make sure you installed the gasket and that is torque down to specs.(you may try some silicone,not too much)
You will have to locate the source of the leak before you can fix it. Re-post with your findings.
You have to determine the source of the leak then decide on how to fix it.
depends where the leak is, and how bad it is.
antifreeze leaking into the oil pan
You will need to replasce the heater core.
Pressure test system to determine where leak orginates to determine fix
Find source and fix it.
Have cooling system pressure tested to determine origination of leak
by getting a Bars Leakradiator leak at walmart
Depends entirely where the leak is coming from.
Coolant leak, possible heater core. Suggest to have it pressure tested to find leak.
An automotive product called "Bar's Leaks" will effectively seal any "small" coolant leak in the radiator but if the leak is coming from the engine area; this may require new freeze plugs and/or block sealer if the leak is not too serious.
It is possible. However, it will be a temporary fix.
I had an external antifreeze leak, and I tried a product called steelseal and it worked as advertised, just took off radiator hose and added the product as per instructions still no leak, i think it messed with my thermostat though.
We need to know where the source of the leak is coming from to answer that one.
A part has failed. Find where the leak starts, and fix that part.
The engines thermostat is probably stuck open or has been removed, so change the thermostat and this should fix your problem.
Not enough information supplied. Dust leak coming in WHERE?
If you are referring to antifreeze loss in an early Ford Focus, I can tell you that this is typical. The thermostat housing mounted to the engine block is plastic and is notorious for warping and developing a leak. The only way to fix this is R&R the housing. I recommend an aluminum one that is less prone to warping in the future.
Remove and clean the petcock. Replace and if it still leaks, replace with a new petcock.
You need to have your antifreeze up to par and if it is a leak you are worried about until you get somewhere to have it fixed there are quick fix solutions such as Barr's Leak that you can use it will seal the leak temporarily to get you to where you are going. Do not ever open your radiator cap if your car has been running - only open it when it is cold.
Could be a few things. Does it leak antifreeze? if so, fix the part that leaks. If not, you could have coolant mixing with oil inside the engine, which burns it. check your spark plugs. If they are white, you are probably burning antifreeze - fix immediately. your exhaust will smell "sweet" as well if you are burning antifreeze.
Pretty much going to have to replace it. Because of the pressure involved, there is no easy fix.
Depends on where in the cooling system the leak is. Some choices are: -Busted hose Find and replace house -Bad radiator Replace radiator -Leaking thermostat housing Replace thermostat housing and gasket -Failing water pump Replace water pump. While doing this, replace timing belt, tensioner, and idlers, as this is quick task, replace it all while you are in there.
