Yes you can, but the car wont come up to temp (or may take a very long time) ... which may cause other issues with the injection system running rich .... the thermostat is only a couple of quid to buy (dont forget to replace the sealing ring as well) so I'd change it as well unless your leaving it out to test for something else.

Depending on the mileage, I'd also consider changing the water pump as well since the radiator is out ..... becareful if you have A/C as the screws/bolts that hold the condenser to the front of the radiator are a pain in the ass to get to (esp the ones from below the bumper) .... make sure you have seperated the two units before trying to remove the rad, as the A/C parts are very expensive and if you disconnect it you will need to pressure check and re-gas the system .... expense you dont really need ... just take your time and take care.

Hope it helps

Why is it the older I get .... the better I think I was ?

Thankyou all so much.
New rad in which was a problemas my 2.2 auto with aircon has a 2.0 manual non aircon rad in it and new temp switch which links to the ecu so i was told and it is all working with fans.
might still buy a temp gauge sensor as its the only on not replaced.

I'm just finding my feet in this forum. I have an 04 espace 3.5V6 at 100k miles. It overheats in traffic but not on the motorway. I notice steam escaping from the bottom of the header, is this normal? The fan works, are they speed regulated, and how would I tell if this wasn't working. Any other ideas? Yours Max

espace cooling

If its a MK3 (up to 2002) they have truly massive cooling systems, especially with air con. Mine is a 2002 2.2 diesel. It always used to run only 3 bars on the temp guage but now is climbing up to 4. I suspected something was wrong so let it idle on the path for 40 mins. Never showed any hotter on the gusge and fan only cut in if I turned on the air con (apparently the fans work all the time the air con is on). Took it to the dealer. They checked it - it was running at about 88 degrees c with 4 bars lit and they said it may actually cool down when left idling - so big is the cooling system and rads. They falsely input higher temps using their laptop and the fan cut in at 97 deg c. This would equate to about two thirds to three quarters of the bars lit up on the temp guage. mechanic told me they rarely cut in except under very hard motorway driving or pulling heavy load like a caravan. They do have two temp sensors though, so either one could be shot. Rather than over heat the thing, get a dealer to test it out before you do any damage
