Expansion Tank Upgrade Question For Freelander 1

[CJ1]

A lot of people on here know I have spent a crazy amount on my Freelander 1.8 which now has a replacement engine with a warranty on it, however I think there is a possibility that my car is losing coolant again. Only a very very tiny amount. It may be the way I have parked, but not sure.

Anyway what I want to ask is: The cap that goes on the expansion bottle does up tight and then clicks and loosens itself slightly without it unscrewing but on the old tank the cap screwed on tight. Is my expansion cap supposed to do this? Or do I need to find a replacement cap?

Cheers.

This is normal for the later tank

Due to the amount u have spent I would recommend if u have a 1.8 to fit the coolant level sensor mod as will save the engine if the level drops

As for ur loss I suspect it's the heater matrix ??

I can't find any info about the sensor mod but am very interested. Please could you tell me more?

Also looks like the water leak was just me being paranoid lol.

Also interested in the coolant level mod. Looking on the internet shows a number but wondering if there is a recommended one?

Hi there is a tsb from l/rover

If u contact ur parts there is a kit for pre or post 1a 1.8 if u have a pre 1a it includes a jumper loom connects below the engine ecu where there is a row of connectors (n/s). Also a new header tank and float sensor unit.

On post 1a u get a small loom from sensor to ecu where u add 2 wires to the main connector on the ecu. Both put the engine warning light on when the level drops to low ( does not store a fault just top up and light goes out)

Note for post 1a will need software update to work correctly normally dealer charge 1/2 hr

Hope this helps when I am back at work will add the bulletin number ( on course at mo at gaydon)

i am interested in knowing which part number for the tank with sensor if it can fit on a V6 FREELANDER , advice as in africa it is hot and most freelander has problems of over heating. what is the best way to resolve the problem.

I couldn't find any more information on the genuine part, but it would be very easy to buy an aftermarket level sensor off of somewhere like Ebay and retrofit it to your car with an led light mounted in the cabin somewhere.

see item 11 in http://lrcat.com/37/4/48040 listed as header tank with sensor

sensor on it's own looks like this http://www.lrseries.com/shop/product/listing/15118/3311/4/PCJ500010-EXPANSION-TANK-SENSOR.html

thanks i have checked out the ref pictures you have given on the tank ans sensor.

but it is like they fit on VIN 5A476243 on wards, can they fit on VIN LESS than 5A476243?

what modifaction can be done on a car? if less than 5A476243?

[western]

there is no reason why you cannot fit it to a older vehicle.

Hi

slightly off topic, my 05 Freelander has the coolant level sensor

Recently after a few miles the warning light comes on even though coolant level in expansion bottle is fine

After a few hours with the engine switched off the light stays off but comes back on after a few miles

Thanks
