Well once again my UIM gasket needs changed. I got the car from my dad as a hand me down. He had a garage change the upper and lowers in 04, but the jackass at the garage didnt change the UIM, so now once again it is leaking coolant behind the throttle body. Luckily for me I noticed that it was slowly leaking coolant, and there is no coolant in my oil its just leaking out of the engine/ not in.
The car is a 95 se with 114,000 miles on it. so i figure it is worth it to change the uim and gaskets, I have already ordered the part. My question is; since i am only changing uim and uim gasket, how muck coolant do i need to drain and how do I get it out of the UIM before i start. Im not changing the lim gasket because it only has 25,000 miles on it and it is not leaking. By the way my car came off the line with the green coolant in it and thats all i've ever used. is there any way to clean the injectors while they are out??
Any and all advice will be greatly appreciated. Thanks in advance

You should be able to do it by just draining the radiator. I use a small diameter vinyl tube snaked down to the bottom of the radiator side tank and siphon coolant into clean gallon jugs. The siphon usually breaks at right about one gallon, and everything stays so clean that the coolant can be re-used. This is all I do for changing thermostats and it works very nicely. You may want to be careful how you re-fill to avoid trapping air in the engine. Here is the re-fill method from Techinfo: http://www.bonnevilleclub.com/forum/...=article&k=100

Thanks Bill, I read that in the book, but they mentioned taking the drain plugs out of the engine. This seemed unescessary since im not taking the lower off. Thanks for clarifying, and also for such a quick response

I was reading the tech info, and had one question. Is the drilled thermostat supposed to be reused?

the thermostat can be re-used but if you take it off, i would replace the gasket.

Rubber seal AND gasket.

I'll be sure to change both the o ring and gasket for my thermostat. Thanks for the advice guys. does anybody know the part number for the coolant elbow that goes into the tensioner assembly?

Just get one from the "Help" product line from most any auto parts store. The package sells for about $6 with two elbows (you will only need one on your '95, the other elbow is for the water pump fitting on newer tensioner assemblies). Each new elbow will have new o-rings.

Alright Bill, thanks again for clarifying. I'll be sure to update with my results.

You don't replace the elbow if you are doing just the UIM. If the elbow is leaking and you are not removing the LIM, you will have to remove the tensioner.
