I have a DeTomaso Charade which has a 1.5L Applause motor with a 1.6L head, (HD/E Motor) rebuilt at 159k, ran fine then sat barely started for 3 years. I've recently started having over heating problems, I have removed the thermostat and put in boiling water and it opened and I have water vapour coming from the exhaust. My questions are
1) will the thermostat work if it is installed backwards?
2) is there an air bleed for the cooling system on these engines?
and 3) will the heater hoses installed backwards cause overheating?

any help would be greatful,
Cheers

First I don't think it is possible to install the thermostat reversedly and if you can, it definitely would not work.
No, there are no air bled valve for your engine. You need to run the engine and wait for it to cool and top up coolant as necessary.
No, the heater does not have anything to do with overheating. Only way it can cause that would be allowing air to be trapped in the heater core.

When does the overheating occur and did you check if the cooling fan is working?

The thermo fan works fine and switches on and off as needed, overheating occurs after about 15 minutes of driving. Overnight I replaced the thermostat, while doing so I noticed a shield that wraps half way around the thermostat, I poked around inside the block where it goes and felt a little hole( about 10mm) and that shield was covering it up, I turned the thermostat a full 180 degrees and installed it, because I had a newer radiator laying around I installed that too. The newer radiator is from an auto so there is a small pipe on the bottom, where does this go and can I just block it off, temporarily I put a piece of garden hose on it and tied it up higher than the radiator, 10:30pm by this time I start the car after replacing coolant, idled for 20 mins fine, temp guage as normal, once I work out what to do with the outlet on the bottom of the radiator I can drive test it.
Thanks for your quick reply

Oh and no the pipe on the bottom is not the transmission cooler lines, I've capped those already

Guess the thermostat was not installed correctly the first time.

Apart from the transmission oil cooler hose, there are no other hoses except if any is attached to the drain plug outlet, which should be left where it is.
