Does an Intermotor 75213 thermostat fit a Rover V8?
This opens at 78°C but I can't find a picture of one - does anyone know if it fits?
The diameter is about right but the length given is about twice that of my current thermostat.

I was going to replace my jammed 78° stat with another but couldn't find one so fitted a spare 82° stat I had in the garage.

I don't think its overheating but perhaps it doesn't seem to run quite so well as with the cooler stat?
I've got a new 74° stat (a spare from my old Land Rover) so I'll fit that instead.
Well I assumed you were talking about your Rover engine when you said "in mine".Darkspeed wrote:Depends on if I think its needed really so many different applications.Denis247 wrote:Do you drill a hole in it?Darkspeed wrote:I always run Mini summer 74 degree stats in mine.

I have had quite a few and they have had different manifolds and cooling layouts and in every engine that I have owned (mine) I use 74's and sometimes I will drill a hole and sometimes not depending on the manifold type and the colling system installation.Denis247 wrote:Well I assumed you were talking about your Rover engine when you said "in mine".Darkspeed wrote:Depends on if I think its needed really so many different applications.Denis247 wrote:Do you drill a hole in it?Darkspeed wrote:I always run Mini summer 74 degree stats in mine.

I believe modern engines run hotter for reduced emissions - it's why the 4.6 Rover has a hotter stat than previous capacities.
I always drill a hole about 4mm in the flange and fit the it with the hole at the top - I reckon it helps get rid of air bubbles behind the stat. Some have a hole and jiggle pin which is supposed to keep the hole clear but I always remove the pin, partly because I've never seen the bleed hole blocked on any of my thermostats and partly because I don't want the little bit of brass blocking a rad tube or getting into the pump if it becomes free.

Likewise I always remove the fitted 'jiggle pin', not just because I don't want it to end up circulating in the system, but the end is a nylon blob, which effectively blocks the hole under pressure from the water, and I want a little water circulating here to ensure there's not a slug of cool water trapped that could delay the opening of the thermostat.ratwing wrote:I believe modern engines run hotter for reduced emissions - it's why the 4.6 Rover has a hotter stat than previous capacities.

I had an Uncle who was a seriously Old School motor mechanic and he told me to remove the stat from the car, cut the spring and gubbins out of it and stick the body back into the engine to act as a restrictor for flow.
To be fair, it didn't freeze where I lived at the time, but my 1275 Mini seemed happy enough with the change.
