Jimny running hot ?

Sorry I can't...

Here in Denmark we only have digital watches :laugh: :laugh:

The wife's is running at just over halfway as well. Thought it might be an issue, but it seems not. Phew

Has anyone fitted a thermostat with lower opening temperature?

Was out driving today and thought the engine smelled rather hot, like a slipping fanbelt. Only this is not the case. The Valvecover also felt very warm.

The standard thermostat setting is fine. If it's running hot fix the cause not the symptom.

Radiators get clogged easily on Jimny's as the fins are fine and close together.

My Jimny runs between 89-91c all year round on my scan gauge - which brings up back to the suggestion of having one to see the actual temperature made earlier in this thread. The car's guage doesn't move past the half way point no matter what the temperature. When I had a clogged radiator it went up to 104c - quite alot for a system that does not have much pressure by design.

You've been on here long enough to have read the posts about the viscous fan unit breaking down, thermostats not opening enough / sticking and radiators getting clogged etc.

Work through it systematically until you find the solution, but nonetheless for the money it costs a new radiator would be the first thing I would do as in any case it can do no harm and only good.

If you get a scan gauge you can see the results to the degree c instantly for any changes you make and see problems in the cooling system rearing their ugly head early - like I did.

Without looking up what engine you have Tom, changing the thermostat on a twin cam is a pain in the back side. So if there is nothing wrong with the one you haveand you have just got a clogged radiator, change the rad and put in a high concentration of coolant back in to prevent sludge build up and rust in the system and the thermostat should last ok.

If the fan belt was slipping I would have thought you'd have heard it, but again, for what it costs, change it and the power steering belt and leave the old ones in the boot as spares.

My engine is a G13, so changing the Thermostat is no big deal. Which I've also tried, but with no change. My temperature gauge goes up to around 3/4, so the gauge covers the temp symbol.

I'm just beginning to wonder as I tried driving the Jimny with the thermostat removed, and then it took about 30 mins I'm wrong.

I don't think it's the fanbelt slipping, none of the belts appear warm, worn or anything.

So, for starters I will try removing the radiator and clear it inside and outside.
