Radiator Replacement 940 2l Petrol - thermoswitch?
Over lockdown the radiator has developed a small leak, judging by the drips under the car and the rusty residue on the plastic side tanks (passenger side).
Looks a relatively straightforward job and it will provide the opportunity to finally do the coolant flush and replace the thermostat I've been meaning to do since February. Just slightly stuck on which rad I need. I've measured it so I've got the dimensions nailed down but it looks like there are two versions - one with a thermoswitch, and one without. How do I know which one I need? 2l Petrol Manual, non-a/c, '92MY. thermoswitch version: https://www.ebay.co.uk/itm/NISSENS-C...UAAOSw6TRatcW5 non-thermoswitch version: https://www.ebay.co.uk/itm/NISSENS-6...N/291580031272 Coolant-wise I'm going to do a reverse flush. Looks like capacity is around 10l? So 5l of ethylene glycol and 5l of water?

If you have an electric fan you need a thermoswitch
Coolant capacity is more like 8L Your current coolant looks like it's got half of Bournemouth Beach in it

It's 8.5L. Either use Volvo genuine or Comma Super Coldmaster / Xstream G48

The 940 doesn't use a sensor in the rad for the electric fan, the fan is controlled via the ecu and used the temp sensor on the head

Thanks for the swift reply - viscous fan so no thermoswitch needed. Thanks for advice on coolant too. Agree - not happy with how rusty it looks!

That's interesting. I have old skool viscous but broke a celebration with electric fan. How does that work with a swap to electric then ?

If you were prepared to cut the top hose, it's easy to fit an adaptor and thermoswitch. All depends what you already have and could make use of really.

It's a two speed relay that's situated in front of the battery. I'll have a look to see if I have any wiring in my car which would plug into relay. My logic thinks there won't be but you never know
