Really not too sure what a 'bioter' is! But anyway, remove the negative battery cable for about a minute. That should make the light go out! If not you will need to have the codes checked. OK Frankster016

Is it all one piece, the outlet pipe and the t-stat housing? The gasket goes on the bottom of the housing where it mates to the engine. If the coolant is leaking from the bottom of the housing, that would require a new gasket. If coolant is leaking where the radiator hose connects to the pipe, have you tried tightening the hose clamp? If the outlet pipe and housing are separate, there may be an O-ring seal between them. You may want to pull off the radiator hose and check if the pipe is so badly corroded and rusted that it cannot seal anymore, or may have a hole in it, especially if it is thin metal.
the 1993 caravan had two engines offered a 2.5L 4cylinder and a 3.3L v6........on the 2.5L the thermostat is located on the front of the cylinder head were the top radiator hose attach's.
remove the top hose were it attach's to the thermostat housing and the remove the thermostat housing and lift out the thermostat and replace with the new one making sure the spring on the thermostat is facing the engine replace the thermostat housing and top radiator hose and remove the bleeder screw from the top of the thermostat housing and fill radiator with new antifreeze. when you see antifreeze coming out the bleeder hole replace the bleeder screw.
The 3.3L v6 also has the thermostat at the front of the cylinder head were the top radiator hose attach's the thermostat housing the procher is the same except for bleeding the radiator, to bleed the cooling system remove the coolanttemp. sensor it is located just below the thermostat housing and fill radiator with new antifreezeuntil the antifreeze starts coming out the coolenttemptsensor hole them reinstall the sensor and top of radiator.........GOOD LUCK
Your Thermastat is located in a Dome Shaped Housing,just take your hand put it on upper radiator hose and follow it to the engine ,you'll run into a hose clamp around the hose thats holding it on the Thermastat Housing.
Make sure your car is cold, then put a pan underneath vehicle below the thermastat housing,You'll loose a Little Coolant ,So this Way you can catch it.
Just Loosen the Rad. Hose Clamp and Pull off the Hose from the Thermastat Housing.Then you'll have a couple bolts holding on the Housing,Remove the Bolts and The Housing should be FREE to come off.If its a Little Stubborn ,Lightly Tap on It with a Plastic or Rubber Hammer a nd it will come off.Your Thermastat is under the Housing.
After off Clean Both Surfaces on the Housing remove All the Old Gasket material and Gasket Sealer .Then just put your new thermastat housing in with the Spring part facing Up.
Put Gasket Sealer on The Thermastat Housing and Put new Gasket on and Line up your Bolts Holes.
And Also piut a Small bead og Gasket Sealer on The Engines Surface. Tighten Down Good and Snug ,But Don't Over Tighten.
Put the Hose back on Tighten Clamp and Fill Radiator Back up to Top.
Please let me Know how my Answer and Solution Helped you By Voting .Thanks From d_hubbs
yes, you can do it with minimal tools. First though, please see my tip at http://www.fixya.com/cars/r5929960-s_thermostat .These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.
Here is the procedure for your car:
Disconnect the negative battery cable.
Drain the coolant.
Remove the air intake duct.
Disconnect the radiator hose
Remove the thermostat housing.
Remove the thermostat.
Clean all sealing surfaces.
Fig. Thermostat and housing-typical
Install the thermostat.
Install the thermostat housing using a new gasket.
Install the thermostat housing bolts and tighten as follows:
think you had a friday night monday morning one ,some of the problems are of your own making though ,clutch?? drivers seat broke twice ,how much do you weigh ?? do you like a big mac ?' ,water pump ?? and it went a month later was it fitted correctly first time ,wiring problem with fuel injection was it damaged when changing water pump by taking engine mounting off and jacking up engine ?? .but some of the other problems are not of your making though like the speedo or radiator ,just a friday night monday morning car and i see them on all makes ,try a seat next time ,lot better build quality
Put a bucket under it, and open the radiator drain valve. Find the upper radiator hose. Follow it to the engine That which it is pushed onto is the thermostat housing. Unclamp the upper radiator hose at the engine. Pull it off of the thermostat housing Remove the bolts holding the thermostat housing to the engine, & remove it Clean the gasket surface on the engine, and on the thermostat housing place the new thermostat in position. If the thermostat is vertical, I put a liece of dental floss or sewing thread through it, thered them out the radiator hose hole, and hold both ends to keep it in position. The copper button goes on the engine side, leaving those supporting arms to wrap the thread through. With the thermostat in position, and the gasket in position, replace and tighten the bolts to attach the thermostat housing to the engine. Remove the thread if you had to use some. Push the radiator hose onto the thermostat housing. Tighten the hose clamp Refill wit coolant. If the coolant in the bucket is clean, use that. If not, refill with fresh coolant, using the proper mix of water and antifreeze. (Yes, you need anti-freeze in the summer. It raises the boiling point, reducing the risk of a boilover.)
The thermostat may be sticking or stuck. Start the engine while it is cold and locate the upper radiator hose. As the engine warms up, lightly grab the hose with one hand for a few seconds to see if it is getting warm. When the thermostat opens, the upper hose will be very warm to the touch (so be careful) and have pressure in. If you can grab the hose and squeeze it with little resistance while the engine is hot, the thermostat is faulty and should be replaced. It will be located where the upper hose sits on the engine side. There should be 2 or 3 bolts holding the housing on that need to be removed. BE SURE THE ENGINE IS COLD AND THE RADIATOR CAP IS OFF BEFORE YOU REMOVE THE BOLTS. Loosen the clamp on the hose at the radiator. Place a catch bin under the car because coolant will spill out when you remove the housing. Use a flathead screwdriver to pry it off if you have to but be gentle and careful. Gently remove the hose at the radiator and the housing will come out with it. Remove any gasket material from the the housing and block surfaces and clean them up with emery cloth. Pry out the thermostat. Take the new thermostat and drill a small hole in the flat surface on it. Remove any metal shavings and set the thermostat back in. Set the gasket in place and tighten the bolts very snug but don't over tighten them. Install the hose and housing. Fill the radiator with coolant then start the car with the radiator cap off. let it run while it warms up. Once the thermostat opens, have someone sit in the car and raise the rpm to 1800 to 2000rpm and hold it there while you top off the radiator and tighten the cap then test drive it. I suggest replacing the radiator cap with the thermostat. Parts and coolant should be no more than $30 to $40.
Your thermostat is located under a metal housing on the top of the engine. The upper radiator hose connects to this housing. To change the thermostat you basically need to drain the radiator after your engine is cold, disconnect the upper radiator hose from the engine, and remove the bolts from the small housing. replace the thermostat, and clean the surfaces on both sides and replace the gasket too. reinstall the housing, attach the hose, and refill the radiator. start the engine, warm it up and check for leaks, then re check the coolant level after the engine cools off again. Here's a link to a good article on replacing your thermostat... http://www.automedia.com/Keep_Your_Eye_on_the_Thermostat/ccr20041201th/1
Remove cap radiator when cold
Drain radiator well below thermostat level.
Disconnect rubberhose from thermostat housing to radiator. Do this at radiator side first cautious to prevent blocked fluid to run over engine . Undo radiator housing cover. Be sure to have new spare gasket. And right type new thermostat with corresponding temperature opening rating.
Take out thermostat. Put new one in in the good position not reversed down (it opens at temperaturing pupping upwards. Check for presence of de-airation hole with little valve.
Put gasket and cover . Tighten the bolts without killing them. Fill radiator to level. Leave a while do de-air leveling over that little hole valve in thermostat I mentioned. I necessarry fill again.
Whilst doing this job be sure the seizure of old thermostat was not due to broken down cooling pump, broken radior fan with activating switch on engine block. At times they go together.
Don't fill with pure water unless for backflushing system. Otherwise vapor bellows in th system will crack the engine block. Some hotspots exceed water vapor point!!
Check the coolant level, do this with a cold engine. Or if you have recently used it. let it cool down for about 25 minutes before removing the radiator cap. if it is low, refill with coolant. If it does not, check your thermostat. Or better yet replace your thermostat. Be sure to get the right one . the same degrees as your old one. Just ask the teller to give you one for your engine size and car Model.And year.See where the radiator cap is. Then drain some coolant to where it will not spill from the radiator cap. Remove the hose nearest the radiator cap and you will get to the thermostat housing. Remove the housing and note how the thermostat is placed. Take of the thermostat housing and the old thermostat. Clean the housing and around the hole where the thermostat goes of any deposits. Get some grease and cover the new gasket with grease on the housing to hold it in place. replace the New thermostat and make sure it is flush with the engine and the housing. If it is off , you could break the housing upon tightening the housing.replace the hose and refill with coolant slowly to eliminate any air spaces.. Also check the coolant reservoir and fill it to the indicator line. Restart the car and chek for any leaks. Then check the heater after the engine heats up. If that does not do the job it could be the temperature sensor or the heater core.The heater core will take more time to check and clean or replace.
