Coolant capacity?

Dear Ferraristi,

3 gallons where there should be 5?

Did you only drain the two rads? Did you forget to drain the engine block?

The block taps are a brass bolt head next to each distributer cap. ( one tap per cylinder head)

....wait till you drain this....then you can talk about a mess.

If the exhaust needs to come of for some reason I do that first, then drain, otherwise it is just get it in and all over the precats etc. If you do that though let it run for a long time in a well ventillated area without people or buildings close by down wind. Ethelyne glycol vapors are posionous. Large quantities are not so good.

P.S. When refilling the climate controls need to be on and turned to hot with the key in the on position to fill the heater and plumbing.

 

Dear Ferraristi,

no....clutch not back in yet.

I just finished researching loctite 518 vs, Hondabond. I've got to order the 518 and the matching primer to stop an oil leak wicking out one of the cross bolts above the RMS.

I've also got to post on the clutch cir clips....yes or no...issue or not.

...but the clutch sure looks nice sitting here.

To drain the coolant from the block...

Have the car on some jack stands. Get one of those large 15 qt oil pans. Cut the drain area off so you have a large open shallow pan.

Place under the center of the bell housing. Get some plastic pipe and a couple of elbows from home depot. Make up the plastic pipe to go from the block tap to the pan....no glue needed.

Once you open the hex bolt, quickly place the pipe at the tap and direct towards the pan. Just hold it in place....it will only take a few minutes ( expansion tank cap off ). I've used this method for years and the mess is very little.

I drain my coolant once a year twice. I drain the coolant, fill with flush and distilled water. I then bleed, put back on the road for a week....drain,and refill with coolant.

....it's a pain, but my coolant system is clean as...um.....fresh panties!

....yeah, you know I had to say it!

Guys, I know this is an old thread, but I have had a search about too.
I am changing my Testarossa coolant.
Manual says it is 20 litres, but I can only get 15 litres out of the car.
I have set, and left, the cabin to hot (checked it by runing the car up first), I have drained both rads from the 2 drain plugs and both heads from their 2 drain plugs. I then jacked up the front of the car, so front wheels were about half a meter off the ground and another 2 litres drained out the heads. Total evacuated is only 15 litres. Where is the other 5 litres, seems a lot to be stuck some where.
Any ideas guys?

 

about 3-4 ltr still in the engineblock

 

Was the engine low on coolant originally? I completely drained my coolant when engine out, and took 5 gallons US. to refill. I mix concentrate coolant with distilled water 50/50 before adding in all my vehicles. Anti freeze bottles on my shelf labeled 50/50. So if any vehicle needs coolant I add, and it always correct mixture.

 

I have a process similar ..I drain system and add distilled water to fill ..run till hot..cool ..drain..fill with distilled again ..run hot..cool..drain ..if still not clean ... fill with distilled ..run hot ..cool drain..then add 2.75 gallons of straight antifreeze and top off with distilled until full ..each time following the few instructions in wsm ..in terms of bleeding valves and heater controls

That gives me a little more than 50/50 and no old stuff left

Any idea how i empty the block of coolant. Or do I live with it and assume that before refilling that there is about 4-5 L already in the motor?

 

Did you also have the 3 bleed screws open and the radiator cap removed? I just did this on my own TR (without the extra effort that you added) and got much closer to the "dry" capacity specification (5 US gallons to refill -- same as ago car nut).

 

Wow, this is an old thread!

I think flash is doing things the hard way.

I jack up all four corners on jack stands. I open all the bleed screws, tank cap and all 4 drain plugs...two on the radiators and two on the block....just as Steve (91tr) has said.

Since I change my coolant once a year, you really don't have to worry about getting every little bit out.
Many many years ago when I got my Testarossa, I had to do a chemical cleaner with distilled water flush for a few years. The water was orange from the expansion tank deteriorating and leaving deposits in the engine. Now when I change the coolant, it's crystal clear green.

I do the same as you ..just more flushing with water ..probably overkill ..I don't drain block due to worry about plugs getting stuck..I spend a little more time I am sure

The block plugs aren't an issue...they're brass. When you take them off, use a long breaker bar on your socket/ratchet and turn slowly. This will allow it to break loose without scarring the hex head or it slipping onto the distributor caps.
When you put it back, use a coating of copper antiseize. You will never have a problem again.

Thank you for the tip .always hear horror stories about distributor

I did a thread on the coolant change with pictures. I thinks it's called coolant change on a Testarossa....something like that.

Yes I had the expansion tank cap removed. However after draining each one of the plugs in turn, the flow turned to a dribble and then a drip, I dont see that the bleeds being open would make a difference, but I can try it next time. I ended up with cap off and 4 drain plugs removed..... I doubt there would be an air lock holding 5 litres back.

 

may be your radiators are blocked ?
so some debris inside? overgrown with lime?

 

The water was clear green that came out, and it flowed out rather well, I don't think they are blocked.
If i turn the engine over for about 5 seconds, when the coolant system is empty, maybe the water pump will empty the block into the rads and I will get some more fluid out. But maybe not ...... as the thermostats will be closed. Thoughts?

 

Engine flush is an invitation to disaster.

Pulling the block plugs is also an invitation to disaster.

Avoid both those problematic issues by changing out the antifreeze on a more frequent interval. Use ONLY distilled water with your coolant.

Cheers,
Vincenzo

 

I am truly basis to my technic ..been doing this to all my cars since I was 18 ..except I was smart enough to switch over to use distilled water instead of hose water in the 90s

Safe ..and totally flushes the system and makes sure precent is correct

When I say ‘flush’ as a disaster, it references products like this:

have a look here:

waterless coolant

does someone has experiences with this kind of coolant?

I never tried but like to when I will be back in my garage again. 1 of my customer has it in his MG V8 and is very satisfied.

 

i hear that the Evans product is good, especially in cars that have cooling issues.....but I dont have any cooling issues.
