93 grand marquis leaking water in this causing car run hot


It appears you have a leaking heater hose or heater core, which is located behind the engine, and goes from engine to firewall. Check your heater hoses coming from firewall.

How to fix a coolant on a car


How to Fix an Engine Coolant Leak Your car's coolant system consists of various components. The water pump, shaft seal, radiator, heater cores, freeze plugs, hoses and the engine itself are areas where leaks can occur. The solution for fixing a leak depends on where it's located. Read on to learn how to fix an engine coolant leak. jQuery('.intro .thumbnail').each(function(i,e){ jQuery(e).find('img').one('error',function(){ jQuery(e).remove(); }); }); Difficulty: Moderately Challenging Instructions
  1. 1

    Locate the leak. This can be difficult, so take your time. Some leaks, such as those in the freezer plugs, are behind the engine mount or other components. You may need to inspect the car from underneath to detect this type of leak.

  2. 2

    Buy an anti-leak product and add it to the coolant to fix small radiator leaks. You can find this product at any auto shop for around $10. It's effective in 80 percent of minor leaks.

  3. 3

    Patch a small radiator leak by soldering or using a high-temperature epoxy. This is another solution to fix a small leak. Other options are to have it fixed at a specialty shop or simply to replace it. If the heater core is leaking, replacement is the best choice.

  4. 4

    Fix any cracked, busted or leaking hoses by replacing them. Simply remove both clips on the hose, pull off the hose and replace it with the new one. Make sure to put the clips back on.

  5. 5

    Remove a cracked reservoir, clean it and dry it up. Apply plumber's goop, which is a type of glue, and reinstall it. If replacement is necessary, ensure that you route the hoses correctly from the radiator to the reservoir. Additionally, it's important that they are free of kinks so the coolant can flow freely.

I just discovered a small coolant leak underneath my 2000 Rodeo. What could this be from? It seems to be coming from an area behind the engine.


check the heater lines which run behind the engine
the rubber hoses may need to be replaced or the heater core is starting to leak also check in the top of the engine to see if there is antifreeze up on to could be a radiator hose or thermastat gasket

Just had radiator replaced, leak has developed around housing/gasket of hose running to passenger side just to side of engine and slightly behind. My mechanic doesn't know what the part is we are looking...


is it actually on the engine? I ask because you say it is to the passenger side and just behind the engine, that makes me think it is a heater hose, the heater hoses go from the water pump to the heater core which is located on the passenger side, the difference between heater hoses and radiator hoses is the size and of course location, heater hoses are generally about 1/2 inch to 1 inch, with radiator hoses being between 1 3/4 and 3 inches

1997 venture leaking coolant, can,t tell where it is leaking,sems to be on the back of engine somewhere.


You may be lucky and it just the hose clamp that needs to be replaced at your heater core on the firewall. Might as well replace the heater hose if it is the clamp that has failed. There are two hoses from the firewall behind the engine, the other places that coolant would leak from are the frost plugs and at worst the intake gasket failed. Keep me posted and have my fingers crossed it's just a simple fix like a leak from the heater hose. Good luck

I have a heater core leak on my 2000 chevy silverado V6, is there an easy fix?


You can bypass the heater core, you just wont have heat anymore. On the firewall of the truck, behind the engine, you will see 2 rubber heater hoses that go into the firewall. They attach to the heater core. Disconnect them and get a plastic connector, and connect the 2 hoses together with clamps to hold them down. This will stop coolant from going into the heater core, and no more leak.

Where is the heater core hose in my 2000 ford expedition?


check closer to just underneath the firewall--it could be a smaller problem than a heater core--Ford 4.6--5.4 engines have a tube just underneath the intake manifold that the rubber hose goes bad and it will leak towards the back of the engine.Lets hope so-what i hear its very expensive to change a heater core in an Expedition.
