Ok... heres the deal. Did the police oil cooler mod and got everything put back together today to fire it up and check for any leaks. Car fired right up and I ran it for about 10 min. C.E.L. came on, did key dance, came up with 2181. Did search, came up with low coolent level. Kind of figured that!
Question is this... how long does it take for the coolant tank to drain back into the block? Came up to temp and the heater isnt working. Didnt swap thermostats, didnt even take it out. Just replaced the thermostat housing with a BT one. Should I leave the cap off of the coolant tank, or should I let it build up pressure and just let it cool down on its own? Cap on or off the tank?
Any advice would greatly be appreciated. Never delt with this kind of thing before. I'm kind of old school when it come to cars and trucks. Just put antifreeze in the radiator, run car untill it gets up to temp, cool down and put more in it. Is it as simple as that with these newer cars?
Thanks again!:beerchug:

How much fluid did you lose??? Fill the tank to the max line, run the car for a while, let it cool down, check again, repeat as necessary.

Didnt loose any fluid at all. I drained the rad. to install the lower hose for the oil cooler. I did run the car untill it got warm, came in the house to warm up, took a nap, went back out and it had sucked it up. Put more in it and I am letting it idle as I type this.
Strange to me. I take it when the motor cools down, it must create a vacume and it sucks it out of the overflow tank? You would think that once the T-stat opens it would then suck it out of the tank, not before.
Thanks for the responce(s)!

Or you can fill, run it till its hot, let it cool, fill, run it till its hot, let it cool, fill and so on.

Thanks Don...
Thats basically what I have been doing. The C.E.L. has gone away now. Just seems like a big P.I.T.A. to me.
Thanks again!

Inexpensive tool, thanks Funky!!
Someone should do a write up on this and get it into the knowledge base. For one, I had no idea on how to get antifreeze back into the radiator after I had drained it for the oil cooler install. I do though have enough mechanical skills to take things apart and put them back together and I will tell ya, I was sweatin' bullets. It would of really sucked some serious a$$ if I would of warped my heads or cracked one.
Thanks for all the help, and "IF" I ever have to do this again, I will know.
Thats what these forums are all about!!! :mrgreen:
