Ok dokey.
Just drove to work , light traffic and with the engine normal
But with it running, the coolant is now just above the outlet hose...
So I've lost even more.
I'll wait til lunch and 're check a cold engine.
See where it is..
But I'm now very worried.
Also now calling Toyota.
Lucky I've got more coolant to top up.

Anyhow , right sat in car for lunch - checked my ultra low coolant , ready to top up. What.... on..... earth ! It's back up to where it was yesterday. I give up..... |

A STICKING THERMOSTAT may show a full expansion bottle......then when it INTERMITTENTLY UNSTICKS ITSELF, water level will drop dramatically. Is heater operating as normal and is temp. gauge fluctuateful.....?

So...
Out of curiosity, where on my engine - is the thermostaty thingy please.
Remember it on my old mk2 escort many many years ago 😂
Taking it out and wd40'ing it to release it.
Probably can't do it these days with new fangled things 🤣

Jamie.
They won’t reject an engine warranty because of your wiring, lets get that clear to start with. Just remind me how this coolant problem started.

Jamie. They won’t reject an engine warranty because of your wiring, lets get that clear to start with. Just remind me how this coolant problem started. Hi Don It started last Oct in Buxton , driven there for the weekend. Checked oil before journey,drove there on the Friday ok. Had lovely weekend, checked coolant & oil Sunday evening before driving home on the Monday. Oil fine, but noticed pink coolant splashes over the rear of the coolant vessel and slightly on the side of the engine cover. Then noticed coolant was below the low mark by about 10mm maybe more. Alarmed i had lost coolant, I topped it up to halfway between low and max with water. As I assumed it's where it should be. Since then it's kept spitting out coolant as I've described. It seems settled at about 15mm below min , but if I top it up... it just spits out what I've put in. It spits out from spout and cap To be honest, before Buxton I'd never even looked at the coolant. I'd known about oil usage since just after buying the car. It was only coincidence that I noticed the coolant splashes on the side of the engine cover. When it splatters out , it even sits in the rim around the vessel and drips down to bits underneath. I've bought Toyota Genuine coolant to top up now. But even pouring say half an eggcup in , it just spits out. Good to hear from you 👍 |

With there being less coolant in the system.
What does worry me is overheating in traffic ?
Not sufficient coolant to absorb engine heat ?

With there being less coolant in the system. What does worry me is overheating in traffic ? Not sufficient coolant to absorb engine heat ? Basically, no, there isn't any cooling problem per se. The coolant expands as it gets warm / hot. In the old days, any excess coolant would blow past the radiator cap and end up on the floor. That is why we old folk understand that we used to need to remove the radiator cap regularly to check that the coolant was covering the radiator fins. Dumping coolant onto the floor is bad for the environment and repeated checking is a fag so the industry introduced expansion bottles. Now as the coolant expands the excess runs off into the expansion bottle and is sucked back into the cooling system - radiator et al - as the engine cools back down. So, provided that the expansion bottle is never empty you can be certain that there is more than enough coolant in the system to do it's job. So, the expansion bottle should never be full - or else there's insufficient room the handle further expansion of the coolant. Similarly, the expansion bottle should never be empty - because then you no longer know whether or not you have sufficient coolant in the system. And so the Toyota expansion bottle has max and min marks to indicate a sensible level of coolant when cold ... None of which explains why in your case the 'equilibrium level' is somewhat below the defined min / low mark - but it is, and you would be 'mad' to continue topping up so that it dumps coolant on the floor. It isn't a problem per se ... ... but, like you, I'd like to see the explanation ...  |

It isn't a problem per se ... ... but, like you, I'd like to see the explanation ... Thanks for the info Philip, I've been driving around with it like this for months now. I put a clear rubber hose on the " spout" to take splatter mess away from under the bonnet. But , it just took the splatter elswhere. So , I'm not topping up anymore unless it gets silly low. But I'm leaving it about 10 below low mark. It still spits out excess and is making a mess. But I need Toyota to see it when it goes in. I'm also on the fb Rav4 group and there is another chap with 2012 Rav4 with same problem. We both have our Rav's going into Toyota on the same day. But he's now where near me. Looking from a different angle, that coolant may have been below low mark before I noticed it ? I'll never know now. But.. as we both agree , it'l be good to solve what's happening. 😊👍 |

In the olden days we used to put a pipe on the outlet then put that pipe into a bottle, with a little coolant in, then if there was any blow out it would get caught & as the system cooled down it would drag the coolant back into the system.

My mechanic pal always said to check if coolant was low, try running heater.... if heater doesn't work then water coolant must be low. As I like a warm car (its me bladder ye ken) then I always had a running check on coolant level!
With the volvo, it has heated seats and I've yet to discover much about the radiator. However as the windscreen washers have acked up, I have found a rubber pipe that seems to act as an overflow pipe for the screenwash tank which I've never seen before....so maybe its a pipe come off. Result tho is I'm getting peed off with the volvo..far too difficult to work on....4 thousand fuses placed strategically at places where anyone older than 4 can't get their hand in.

Well, I've not put in any since mid last week.
Just driven to another walk , about 50 miles on A12.
Yes it's spat out a little around the rim on the coolant vessel.
But it's sat cooling for an hour now and coolant is still about 10mm below the low mark again.
Where it's been almost all week.
So , it's not affecting driving the car. And the spits are just a irritating nuisance now and look a mess under the bonnet.
But.... it shouldn't do it.
I even took my spare coolant cap apart earlier to see how it works.
I'm tempted to block up the pressure holes at the base of the cap 😂😂
As that is the only way coolant can escape.
Er.... no!

Update,
Cars going into Toyota tomorrow...
But , I've just noticed the coolant in the vessel has got much darker.
And they have said my extended warranty ended last Oct.
My paperwork says different.. ends Oct 2019.
And they want to charge me £55 diagnostic for a fault code.
Now, I think if there's a fault code or would appear in the display ?

Hello.
Did you ever get to the bottom of this?
Thanks.
