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.
Your heater hose burst just inside the firewall, or, your heater core has developed a leak. Either way, you will have to access the heater core to replace the hoses and/or the core. Given the difficulty, I'd just replace both hoses and the heater core. Then it should give many years service. The vehicle "running hot" may be an entirely different issue. As a stop-gap to get it to the shop, you can loop the heater hose so that where the hose comes from the engine to the heater you loop it to the engine inlet from the heater. Takes heater out of the cooling loop.
did you replace the radiator cap. most people forget about this very important part, but with out a pressure test its almost impossible to find the laek unless you can see it. make sure yo run the vehicle & get it up to temp so the coolant will circulate!!!
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
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.
Well this is going to be like finding a needle in a haystack! You can get a test done where they put a flourescent ink in your coolant, run the engine and then go over your engine with a black light. With a leak this small, that might be your best bet!
sound like the heater core. you can bypass the heater core. there are 2 hoses under the hood on the pass side of the vehical on the fire wall undo the hose clamps on both hoses and ties the 2 hoses together
