Re: Antifreeze leaking inside the car
Service engine soon is an engine code not likely related to the leaking heater core. I can almost guarantee your heater core has developed a leak. Bars Leak is recommended from the factory for Jaguars, and might accidentally stop the leak, The only other solution is heater coild replacement, The coil is not expensive, but the labot to install it is. The light indicates a malfunction in engine controls and emissions. Any auto parts store will be glad to run the codes for you, with the codes I can help yuo find a solution to the light issue also. ! Good Luck and I hope this helps!

Is it antifreeze or just water? If water, your AC system will frost up under use, which will melt and pool under the car on the passenger side (normal) after the engine stops. If antifreeze, there is a complicated cooling hose system, with some of them near the firewall. Check the overflow tank to see if you are losing coolant, and if so, check the hoses there while the engine is running.
not good. Sounds like heater core inside the car !
if it leaking in Passenger compartment of car
Check the engine see if leaking out of side of engine. Could be welsh plugs are corroded.. Check when engine cold under the inlet manifold of the engine for any thin rubber hoses that might be hidden from normal view.
Usually when you have these symptoms, the first thing you should look for is coolant in the passenger side floorboard. Just run your hands over the carpet and feel for dampness. if you have floor mats, ne sure to check under the floor mat. If it is damp you are most likely going to have a leaking heater core or heater core hose
are you sure it is water, smell it to ensure it is not antifreeze (smells sickly sweet), if it is antifreeze possibly heater core leak, otherwise check for plugged evaporator drip tube (with a/c of course), could also be leaking body panel (cracked chalking etc). hope this helps
Is there a sweet smell inside the car?Heater core leak I beleive would be on passenger side floor.Antifreeze will be sweet to the nose.Are you getting any white smoke out the tailpipe? would likely be head gasket leak.Put a piece of cardboard under the car near the radiator and under the motor to see where its leaking from .One thing Ive learned over the years is that its going somewhere.On the ground? Or out the tailpipe.
As for the floor board leak the 98 s were prone to have the defrost area in front of windshield collect water from being plugged up .Mine was passenger floorboard.Daughter resealed small oval vent (that defrosts /heats hood?) LOL .Its on pass. side under hood on cowl .I think this will take care of my problem but you may need to investigate under the dash/defrost area and drill and then install a drain line to bottom of defroster.Exit drain line to O/Side of car...lol .Also was it raining ? was car outside in rain .if so it could be this issue.Sorry so long ,hope you can make heads or tails of this.
If you can smell antifreeze from the inside of the car it is most likely the heater core. You can probably feel under the passenger side floor mat and it will probably be wet with coolant..
Replacement is a fairly large job because the dash has to be disassenbled. I would guess at between 300 and 500 dollars.
You should have a local mechanic take a look at it before you buy and get an estimate.
Let me know if this helps in your decision and please rate this solution.
