2000 Lincoln Navigator Question: Coolant Leak

 

Question

I am leaking coolant somewhere behind the starter. It does not appear to be comming from above the the starter. It does not appear to be a freeze plug on the block. Heater hoses do not appear to be leaking. Is the a freeze plug on the block on the rear? could it be leaking between the engine and transmission? I cant see the head gasket behind the starter. What could it be?

    You need to have the system pressure checked and that will force coolant out of the leaking component and there should be freeze plugs on the back of the head and block also sometimes the heater core could be leaking and dripping down to the starter area

    Does the head have to come off to repair this?

    Probably if its too close to the firewall to work on and if the head has to come off its basically a head gasket job and you can check prices on that repair here www.repairpal.com/estimator as if one freeze plug has rusted thru the others are close also to rusting thru

    I found the leak. It was the tube that comes from the block behind the water pump to the heater hose. I had to remove the altinater to find it. The coolant was leaking under the intake manifold and running down ths back side of the block and between the starter and the block. Repaired the tube with JB Weld. Thanks for responding to my post.
