i have a s1 engine in my cabby it starts up and runs fine but the problem i have is if u leave it on idle while standing around the temp gauge goes rite up to just below the red then it coughs and splutters and cuts out but wont restart till it cools down any ideas folks ive changed all the switches and sensors for peace of mind so there all new and the fans cutting in and out if a little late by it is working
any help will be appreciated thanks

 

I have the same problem with my Orion Mk1 S2 RST. If I get stuck in traffic the temp goes up exactly below the red mark. The only difference is that the engine doesn't cut out, but if I switch it off at that moment I get the radiator water coming out. I think the problem is because the exhaust manifold and the turbo are too close to the radiator.

Next week I'm going to install a different fan switch and a turbo heat shield. I will also be checking the radiator and if it results in any minor problem I will put it the Pace Alloy Rad. Try doing these things mate. You can also change the expansion tank to a S2 one.

 

have u replaced the thermostat??

 

yep new one and all the hoses both radiators and the water pump lol i have more or less rebuilt the car before i bring it back on the rd

 

orion rs: The Orion mk1 has a softer spring in the expansion tank cap as the S1.

 

Try taking the Thermostat out altogether. In this weather it won't matter if you have one in. You should notice a big difference in the temp.

People do it but I wouldn't advise it. I't don;t matter about the weather, it wont let the engine get up to temps properly and is not a good idea imo

 

I'd rather the car run cooler than overheating all the time but you could try getting a Thermostat that opens up at a cooler temperature.

You are better off getting a Thermostat for it but I havn't had any problems with my car since I dropped the Thermostat out of it.

its my 2nd thermostat i tried done the same thing with the other one as well so i changed it for another one just in case its got an ally header tank so it has the other type of header cap like the s2

 

Have you tried a lower degree stat? I have a 82 degree in mine instead of the standard 88 degree, how about installing a fan switch so you can manually control when the fan comes in to so you can bring it in earlier well before it gets to a dangerous level in traffic. Also, have you tried another header tank, or flushed the rad and checked for cold spots etc?

 

yeah have replaced the rad for a new one theres no airlocks have ,ade sure off that the thermostat is just a std escort turbo one have got a second fan i have fitted but havent wired it up yet was hopeing to sort out this problem first as its not how it should be if that makes sence i want it running right before i keep doing modifications
