Thread: Help! coolant leak inside the cab of 99 RR.

Heater core O rings by the sounds of it.
Not too hard a job but can be very fiddly & time consuming.

I've been putting mine off for a while though .

Hi mate,

I had a simalar issue and ended up bypassing the heater with a U type join in the engine bay. Not sure if that would work for you or at all on your veh.

Cheers

ps. You can all ways buy a coolant alarm from me, not that dear at all.

thanks mate, how bad is yours leaking however? Mine is fairly noticeable where the coolant can be seen pooling on the carpet and floor. What's involved to change them, getting the pipes off the back of the heater unit, i gather?

Luckily mines just an occasional drip at the moment.

Repair involves moving the heater core back off the pipes. See

I've pulled the underdash panel off and can see that where the metal coolant pipes come in from the firewall to the heater unit, there is a leak at the heater end. Has anyone had similar? I'm thinking of getting some silicon or pipe sealant to try and seal up, hopefully without having to dismantle the centre dash? any help or suggestions would be greatly appreciated, thanks, Ren

G'day Ren,

Ron Beckett has done a great page on how to fix this on rangerovers.net

Heater Core O-Ring Replacement

He gives a complete description on how to fix the problem without taking the car apart. It is for a 95 model, but I reckon the details won't be too different.

Let us know how you go.
