Does any one know of a thermostat that can be fitted inline by cutting the radiator hose?
I'm buying a car with a ford 12v 2.9 v6, modded to run a carb by using a 2.8 manifold. Currently there's no stat as on 2.9 it's on the inlet manifold (AFAIK) and on 2.8 on block. It's been suggested that a ford mondeo has an inline stat which could be used, is that the case? Any other recomendations?

I used a Land Rover inline stat, part number PEM101020. This is basically a cannister with two inlets and one outlet, with the stat inside. It's an inlet stat (it goes inline with the bottom hose not the top hose), it avoids the pressure related problems with a conventional top stat, also has a full flow bypass which closes when the stat opens (iyswim) rather than a conventional small permanently open bypass that you'll find on most top stat systems.

As an alternaive, John Eales does a nice (but rather pricey) remote stat housing that takes a conventional stat and provides a fixed bypass.

How does it know when to open ?

I'm sure I've seen inline thermostat housings, but I can't remember where. I'm not familiar with the Mondeo, so I don't know about that one.

Have you considered an electric water pump (from Davies Craig or whoever)? Standard practice on these is to remove the thermostat and mechanical water pump, since the electric pump doesn't run until the temperature rises. Would gain yo a bit of horsepower, too (since you aren't driving the mechanical pump all the time) and can be wired to continue circulating coolant after switch-off.

You put a T into the top hose and connect it onto the top of the stat, so the bypass flow goes through the stat. Lovely big bypass, loads of flow, no hotspot problems during cold running and warmup. The bypass is shut off as the stat opens, kind of like a central heating diverter valve if you're familiar with them?

Some Renaults used a stat, that you shoved up the inside of a rad hose. No idea what model though, but I first used one in the early 90's, so it must be a car made before then. Maybe a R21 or something ?

Or indeed the old Rover SD1 inline as already mentioned. I had a couple of them from a 2.0 SD1.
Well...think it was a 2.0, it was a few years ago..

Personally, I wouldnt even consider a DC EWP. I think they are a POS.

Im sure you can decipher my abbreviations.
