A lot depends on where the leak originated. If it's the water pump, it will only get worse, circulation will be impaired, engine can easily overheat...won't ;last long. If it's an external leak, and you don't let the coolant get too low, it can go a l;ong time, with daily or regular topping up of the radiator. If it's a blown head gasket and leaking internally, its days are definitely numbered. If its a head gasket and leaking externally, a little safer, but iffy: the head gasket may keep eroding and the leak get bigger. Overheating of the engine may occur.

Its a matter of opinion. Most experts will tell you to change the fluid and filter at 50k and again at 100k etc.If you have not yet serviced it, then yes you should now. Once you pass 100k you run the risk of making the trans not function if you change the fluid-filter. It has to do with particles in the fluid and the condition of the fluid. New fluid at say 150k can be a problem for the clutches.

Hi,Here is a tip that will help you to get better results from your question onFixya.How to ask a question on FixYaheatman101

Fan speed control resistor block is the usual suspect for this. Quite in-expensive $10 - $20 ?
Easy to change, usually. Generally under the passenger side dash mounted in the air flow comming from fan. Maybe 2 - 3 screws on a block with a few wires, looking like it leads into the air cowling. May be behind glove box.
Do not run fan with new resistor out side of the air flow, it may burn out very quickly without the air blowing on it.
