Oh boy. I mounted my cooler behind left fog light right above the left brake duct. I was getting trans fluid coming out the lines. I had to put a bolt in them to stop from leaking.

I guess this will be one of my projects tomorrow in our 100+* heat wave.

When you say start it is that with one of the cooler lines off?
If so which one? Doesnt the fluid circulate fast?

looking at the factory lines which one is coming from trans and which one is the return?

Thanks for your help
Do the line need to be purged also?

 

Do NOT start the engine with any line disconnected. Don't worry about purging the lines, they'll be fine. It just the cooler itself that needs to be full of fluid. If you can move the cooler so that one of the fitting is higher than any other part of the cooler, then you can slowly pour fluid in through the line or directly in the fitting until it's full. Then re-attach the line and run the engine for a minute. Shut off the engine and then maneuver the cooler back into place without taking the line off again.

If this doesn't cure your heating issue, then you must not be getting enough airflow.

BTW. It was only 113* in Phoenix today, so it was cool enough to work outside. JK

 

Well I did the purge on the cooler as you said it took about half quart.



This is how its mounted



Under neath looking up

I also wrapped the headers

This is the trans lines before





Close to the headers

Had to cut and pound out my cats.. This was done awhile ago just a pic





Wrapped and sprayed with DEI


I let the car run for 5 minutes coolant was 175*

Heres a shot off headers temps


This was on header infront of the wrap


Same time just reading temp on the wrap

Well took car out and trans temps creeped up to 212* outside temp was 89*

Still frustrating. Dont know how to keep them below 200* Do I put in another cooler?

How do you fill trans fluid to make sure that it is full?

 

I can understand the frustration. It was 113* in Phoenix the other day and even though I was driving a little spirited, my trans temps had a high somewhere in the 190's. The heavy stop and go traffic is where mine goes up a lot.

If you added a half quart to the cooler, that meant you had a huge air bubble in it, so purging it was a good thing.

Checking trans fluid is a bit involved, and I'm sorry I don't have time to go through it right now. If you do a search and don't find it, let me know here and I'll get back to you later.

ANSWER .........................

You don't need to purge your auxillary cooler. When you R & R your radiator - do you purge your radiator? Of course not. Any air in the system will work it's way out via the trans. I've installed 2 B&M coolers this year and all I do is fill them up with fluid and tighten the AN fittings. Like it was mentioned - air flow is key. The factory mounts all heat exchangers in the direct flow of air for a reason.

To check your oil level:
1) make sure you car is on a level surface and lift it equally on all fours or put the car on a lift.
2) bring trans up to operating temperatures or at least to 125 degrees.
3) with the engine running - run the trans thru the gears. Put it in drive - then reverse. Do this several times.
4) with the car running and in PARK - remove the oil pan drin plug. If oil does not trickle out - then you need to add fluid. Fluid will be added until a trickle starts to come out of the drain plug. Once this happens - the system is full. Remember - This is done while the engine is running and at operating temperatures.

To add fluid while the engine is running - remove a rubber plug on the right side of the trans. You will need a hand pump to add the fluid thru the hole in the trans. Be careful because the exhaust is quite close to these cramped quarters. Good luck.

 

While I'm sure you meant well, but there's an error that needs corrected. The trans temp needs to be between 88 and 122 degrees and each gear selection held for at least 3 seconds. This is from the service manual. Temps outside that range will result in either an overfill (when cold) or underfill (when hot) due to fluid expansion.

Because of the exhaust location like you mentioned, when I check mine, I add a little more (about 1/2 quart) than I think I need before I start the car. When the temp gets to 102 I shift through the gears and then pull the plug and drain the excess. I'm done by the time the temp hits 106 and never get burned on the exhaust.

ZBADESTZ had not prefilled his cooler before he mounted it in a position that trapped air. That's why the purge (or remove and fill) was necessary.

Looking at the pics, I agree with your assessment regarding airflow. There's just too much free space between the openings in that location to do the job, even when using only that small fan mounted on the cooler. When the openings for air entrance or exit are smaller than the cooler, you need to mount the highest CFM fan that fits in the size of the opening. Ducting the air so it all passes through the full size of the cooler is necessary here too.

 

Gents,
Could someone please tell me which is the feed line and which is the return line on the radiator cooler line connections? I want to do the cooler in series with the rad.
thanks so much for bearing with the rookie questions.

 

Use the upper line (return) to your radiator and you'll be fine.

 

Thanks!
so it goes like this: feed from trans to lower rad,upper return from rad to cooler IN, and cooler OUT back to transmission,,, correct?

 

That's the way I ran mine, however disconnecting the lower radiator connection and running it through the ext. cooler first than back to the lower rad. connection and than back to the trans could have a cooling effect on the engine coolant temperature if the transmission cooler is large enough, etc. If not than the trans temp "could" be slightly higher by going through the radiator cooler last instead of the external cooler last, bottom line is that it's most likely 6 of 1 or a half dozen of the other.

PS: using two coolers will increase your overall capacity and by running through the radiator it will help in warming the fluid when cold out and also stabilizing trans temps in a good range. IMHO

Oh, and wrapping your trans lines and/or headers where they are close with high-temp wrapping can only help which I also did.
