Plastic coolent tank questions.

Well, I finally got hit with the cracked plastic coolent tank problem. It just started to crack on the side seem area of the tank and is very slowly leaking under pressure. It is just a couple of drops squeezing out through the crack after each drive. The dealer ordered the parts as well as some coolent hoses; however, it wont come in until the first week of April. My question is if the car is safe to occationaly drive if I make sure the coolent level is full? I topped it off and it leaks very slowly, so it shouldn't get low for a couple of days unless the crack gets larger. The reason why I'd like to know is because we are having a nice NSX/S2000 drive at the end of this month and I really wanted to make the drive. I have a full gallon of Honda coolent in the trunk and don't really plan on driving the car aside from this get meet. Since Hawaii it small, the drive would probably be around 50 miles or so. Thanks.
 
You could always try a plastic glue / patch to see if that holds or at least keeps it from getting worse. You really have nothing to loose but you will want to test it to make sure it will hold. That said - I would use this to comute and not to go on a hard drive as the risks are too high for my tastes.

BTW - there is typically one for sale in the for sale area and it is a 10 min job (or you could get a used one from ERZ motors in the FAQ section) to do yourself if you want to save some $$$/time.

Chris,

I have a brand new one(in the box).If you want to take mine for now and then replace it with the one that's coming in let me know.
 
I bought this sealent that supposed to work on all plastics and be water, gas, and oil proof. It says it can be used to seal leaks under pressure. According to the instruction you apply the clear sealent and it should cure in a couple of hours. For pressure leaks you can then add a layer of tape, then reapply the sealent all over the tape. My crack was right below the forward mount bolt. I cleaned it up and gave it a try. I haven't done the second taped layer is it has only been a little while so far, but the sealent looks like it migh just work. When I get it all done I'll test it out and see what happens. I'll probably leave that 1 bolt off to releave some stress from that area. The new bottle should come in the first week of April so I think this might work for now.

Deuce, if this doesn't work out I'll let you know about using your bottle.

Chris, can't wait to see what your new bottle will look like. Maybe I just might pick one up and keep the new OEM as a spare.

i sealed mine with silicone late last summer and it is still holding after bringing out for the first time this weekend ... but removing the tank was pretty simple...
 
Here's what I was getting at:

Chris, looks good. I sent you an email. The only problem I see with this tank is that it is too nice and flashy that this might be the start of more underhood modifications just to compliment this coolent tank

On a side note. I read the DIY FAQ and it says you can change the coolent tank in a way where bleeding the system would not be needed. Is this true and how do I do this. I don't want to get any air in my system by mistake. Thanks.

Chris ... use Sharpee markers to plug the lines as they are removed from the OE bottle. After the new tank is replaced, and the car is ran briefly, you can burp any remaining air bubbles from the three bleeders on the coolant hardlines. This is very easy, and should only take a few minutes.

Cheers,
