make sure caps on right. Need to check all hoses for splits and leaks and again check the rad core itself. The thermostat is purely a mechanical device that opens when hot 80 ish deg to allow coolant to flow from engine to rad...id remove both caps...idle car and slowly fill both reservoirs until she takes no more fluid. put lids on and allow to heat up and pressurise system. was pressure up and thermostat open if you have an external leak id should be obvious.

keep 1 eye on the temp gauge and if it get too hot i.e after half way shut down....and allow to cool...this would then be prudent to check thermostat by removing and attaching a peice of string and boiling in pan of water...should pop open. if not ....replace.

sniff the exhaust ....and check for vapour and sweet smell ( coolant).

this car got an apexi ecu? ifso you can monitor temps on the hand held commander.

If you remove the plastic ducting and intercooler you can inspect bottom rad hose and back of radiator.

also if you have aircon turn it on and fans should cut in.

thats me off the top of my head.

but if it gets hot shut down to protect the coolant seals.

I'm not at my car atm but from the looks of it the caps are on the wrong way...

I didn't think of that because I never took them off together always one at a time then back on.

With no spring the wrong tank is pressurised and that's why the water is probably being forced out because there is no pressure.

I'll have a look and then post if it was that way round!

If thats case then you in good company because when i had my fd....i did this to mine and forced all my coolant out....hair pulling running around arrggghhh!!! hope this is the case ! fingers x'd

also press cap could be failing...same as mx5! had that as well! and i had an mx5 at the time as well and swapped em problem shifted to mx5!

Seems like they were the wrong way and I have had 0 issues and have just took the car for a good spirited run and got it up to speed with a couple of redlines and seems like no problems!

Got a slight hesitation at about 3k still which could be the common problem people seem to have with the FD!

Thanks again boosted hopefully that's the last as I started it before and had 0 bubbles if I could add a video I would because I had the caps off letting it run and it looks fine!

Warming from a cold start, is this a normal idle to allow the car to heat up?

Just a small video will upload another of the caps!!

cknott94 · July 21, 2015, 10:22:00 PM

Slightly overfilled it but just pushed some out with my finger, one more video know I've uploaded a couple now but just a running list I'll add to this as my own thread!!

cknott94 · July 21, 2015, 10:25:15 PM

Last one from today, just it running and then I go round the car a little bit just to hear the exhaust see if it sounds okay and then as it was pretty much warm just to show no leaks from the bottom as the water was just from overfilling and the levels keeping nicely. I hope it was just the wrong cap placement!!

cknott94 · July 21, 2015, 10:26:12 PM

First video was warm, sorry just showing 3k revs for the engine oil pressure! (:

Woo! Good to know there is people around here, how good are you with coolant leaks?

I would really love to come but the car isn't in top condition at the moment. With the coolant leaking and the possibility of overheating in the engine I don't think tracking the car would help my issues atm!

I'm also getting slight hesitation through the Rev range, still pulls like a train but I can't help but feel I'm missing the full potential. Only way I can describe it is it feels like wheel spin and the revs get stuck, happens sometimes and not others it's doing my head in!

I'm at work till early August but I'm always happy to have a look and help if I can mate.

That would be great! Thanks Neil, whenever you are free I'm happy to meet up and see if you can help!!

I'm on a course next week so in working as well so whenever suits you if possible!

cknott94 · July 22, 2015, 08:48:25 PM

Changed the caps and the dreaded light has came back on to add coolant! In so confused as you can see from the videos no bubbles or anything!!

What else can it be? The fans don't seem to cut in I've heard them come on but they aren't on very often!

Had even more stuttering in the rev range again, will have to see if anyone from Newcastle and on here can diagnose a problem for me to fix hah!

Neil I'll definitely need to take you up on the offer also wouldn't be bad to come see a fellow RX7!!
