Remote Thermostat kit.

Am thinking about buying one from eliseparts at £130. Any difference in these.? Anyone reccomend somewhere cheaper? Can someone fit it for me (for beer or other negotiable payment)??

PRRT - Land Rover Dealer.... about £70. Much better solution. Have a scan thru my engine swap thread for a link to a page that tells you why.

sweet thanks shug

It's not as straight forward a fitting solution, but works better... But read the page and make up your mind which one you want to go for....

What year is your car Tom?

I have the landie PRRT kit still to fit. I have got a plan for an old cooling system layout but not the new one. Not too bad to fit by the looks of things, but then again I havent done it yet.

What difference did it make Shug?

My car is September 98.

I think you will have the revised pipework. Layout like Shugs then (With or without oil cooler!)

1. More gradual warmup, takes a bit longer to get to temp.

2. When heat-cycling the car to bleed the system, we noticed that it opens very gradually and the engine's water jacket seems to see more gradual temp changes. The bypass is of much bigger diameter and it seems to mix the hot and cold more effectively, so you don't get those shots of cold coolant into the engine when the stat opens.

This is all gauged totally non-scientifically - just feeling the heat off various pipes round the engine....

Shug, from what I read you're Land Rover kit would be a bitch to fit (is that right) and that link seems to suggest that the Rover PRRT works pretty well. I'm not technicalogically(

) minded enough to see the difference between the two. Can anyone explain in laymans terms?

Same thing

The PRRT bit simply refers to the actual thermostat that comes with the Land Rover kit (Pressure Relief Remote Thermostat). The only way to get it (in a form you can use) is to buy the LR kit.

May take some persuading the parts monkey at LR that it exists, but persevere, it does and it's an upgrade for the Freelander.

On a later car, like yours, it's actually not bad at all. Just a bit of pipe cutting (not the car's pipes, so it's totally reversible) and finding a bit of ally pipe (I nicked a bit out of an old Rover 214 that was heading for the scrapper)

It's harder to explain in words than it is to do.

Oh, to add - on mine it was a bitch, as it's in the same place as my oil cooler. Not an issue with your car and it wasn't that much of a hassle in the end.

Sweet will get from LR then, cheers

No probs with LR the parts guy (Cupar) knew exactly what I needed and loved the Elise!

The only thing that's delayed me is the coolant drain/flush/bleed

Make sure you refill with the same coolant - older cars have blue mono-ethylene glycol anti-freeze which also contains a short-lived corrosion inhibitor apparently (~2years) - (Lucas seems to be the supplier of suitable concentrated coolant) while newer cars have brown/orange OAT (Organic Acid Technology) which uses a longer lived corrosion inhibitor.

You're meant to stick to whichever type you already have and although it is said that you shouldn't mix them, the main reason not to is just that adding the austrian wine type to OAT reduces the effectiveness of the corrosion inhibitor (the reverse isn't true).

If you're doing a complete flush and refill, you could now fill up with OAT, even on an older car.

For what it's worth, I ran on 50% pyrenean stream water, 50% generic-blue-coolant for about 18 months after Stelvio 2004

Cheers,
Robin
