Reply-To: Volvo303@yahoogroups.com Anyone here ever tried finding a key-lockable cap, to replace the caps for coolant & washer fluid? Just a tad too vulnerable for my taste, too easy prey for pranks and other brainless shit that litters the human genepool....;(( Probably nothing ever happens, but even just loosing a cap (and not knowing if someone put some crap in it) is enough reason to change/lock it.... Fabricating a lockable bracket over the normal cap seems a bit overkill & counterproductive, so a key-cap seems smarter. Not sure though if there are any key-caps that won't jam when being subjected to dirt and rain/frost in that position.... Anyone ever tested with a range of fuel-caps from other brands? I vaguely recall that at least some have a full screw thread, not just a bayonet-kind of design. -- Bye, Willem-Jan Markerink The desire to understand is sometimes far less intelligent than the inability to understand [note: 'a-one' & 'en-el'!] To: Volvo303@yahoogroups.com From: =?ISO-8859-1?Q?Gr=F8nntass?= Date: Mon, 03 Oct 2005 10:52:47 +0200 (CEST) Subject: Re: [Volvo303] Key-lockable caps for coolant & washer fluid?

Before you put on other caps, you should be aware of the mechanismes which are built into the original caps. The cap for washer-fluid has small channels, leting in air. The other one has a pressure-valve to let out air if the pressure gets to high. I've solved the problem provisional by removing the caps, closing with tape and fix it with steel wire. I suggest my permanent solution will be to make a bracket, maybe only on one of the sides of the cap to make it unrotationable. Thus it will not be so overwhelming. The problem is that the closing-possition for the cap might change during time. Another solution might be to reconstruct so the fillings will be from inside the truck. But I've not investigated that solution yet, since the ide is only a minute old.

But I've not investigated that solution yet, since the ide is only > a minute old. Although not perfect, perhaps a bit clumsy looking, I might have found the best idea thusfar: Today I was pondering about key-lockable clamps over or next to these caps, when I also noticed a posting from Mr. Mayberry about loosing his cap. Now, loosing caps, be it fueltank caps or anything else, can often be neatly solved with a small chain. Okay, now you think, 'So what, that still doesn't make the radiator cap easy to lock against theft/tampering, messing around with chain- locks and stuff.' But wait: what about attaching the chain not in the middle of the cap, but on the edge, *plus* attaching the other end of the chain to the mirror-post/-bracket on the front doors?=20 Chain is tight with door closed, relaxed with door open....and door is only open when owner is around, hence still key-lockable....:)) Chafing of the chain onto the body can be easily cured by wrapping the chain in a silicone hose, or using a silicone-wrapped cable right away (depends a bit on how 'rotatable' you make the attachment to the cap). Now, *I* still need a new washer-fluid cap, since mine was replaced with some odd screw-type cap, that in fact became a press-fit cap on the C3....8-)) PS: did I already tell that according to a Dutch mechanic, the small cylindric caps on the windscreen wiper arm (bolt), are the same as from a VW LT? (doesn't help the US-brigade one silly bit probably, but I love folks who spot such cross-references almost instinctively....:)) -- Bye, Willem-Jan Markerink The desire to understand=20 is sometimes far less intelligent than the inability to understand [note: 'a-one' & 'en-el'!] To: Volvo303@yahoogroups.com From: rplars Date: Thu, 01 Dec 2005 09:06:10 -0000 Subject: [Volvo303] Re: Key-lockable caps for coolant & washer fluid?

Is the top of these caps also square? Probably *not* dark green, are they?

Hi, I haven't got any spilling from the filling tap, but I recognise the rising temp from my -67 Volvo Amazon. It has the B18 engine which is very similar to the B30. When the motor is hot from high revving, and I turn it off promptly, it will start to boil. I usually leave on idle a short while (maybe 30 sec) before turning it off which takes care of the problem.

The only solution is to let the engine idle or run at ~1200 rpm until the temp reduces. In my case I wait until either the electric fan switches off or the temp drops to 90.

I don't recall where I ordered it but it was very cheap and easy to find. My original cap had lost its sealing ring and wasn't operating correctly. The flange was also cracked and it tended to cut the hand when removing it. I never had boilover but I did occasionally have some seeping of the coolant. Be aware that the washer fluid filler cap on the other side looks the same, but isn't... the washer fluid cap has no sealing at all, else a vacuum would form in the washer fluid reservoir. If someone has accidentally replaced the coolant cap with a cap meant for the washer fluid, or reversed the caps right and left, that might cause the problems you're seeing. -Dave To: Volvo303@yahoogroups.com From: "brkdrvr" Date: Thu, 16 Apr 2009 20:36:19 -0000 Subject: [Volvo303] Re: Blowing coolant Reply-To: Volvo303@yahoogroups.com On 2009/4/14 Liher wrote: > Hello! > > When I stop the engine after a driving, the temperature gauge raises from > 90C to 100-105C resulting the coolant spilling from the filling tap. > > Does anyone had the same symptom before? > > I guess the problem happens because with the engine stopped the pump doesn't > send the coolant to the radiator, so I give the engine on for 3 minutes... > but anyway it shouldn't hot so much with the engine stopped? Hello, Not having driven my TGB11 enough to cause boil-over I can't comment to much in the causes. I can however state that the expansion tank cap that "came" on my unit was a stock Volvo .75 Bar expansion tank cap found on most 240 series cars from 1976-93 and on many 740's also. As a side note I've had two of the 740 Turbos with Volvo's B230FT (4 cyl 2.3L fuel inj with similar boil over issues. The universal solution seems to be changing from 1.5 Bar(=oem to turbo) to .75 Bar expansion tank cap and allowing engine to idle a minute or two prior to shutting off (also prevents turbo coking but try to explain to wife & daughters). When scavenging or buying a cap look closely if any other color than black which is usually .75 Bar (Green and Grey are usually 1.5 Bar.) The washer solution tank is simply a expansion tank cap with the works pulled out. In the U.S. you can get a brand new .75 Bar cap from FCPGROTON for @ $5.00.

Then it seems as you have the wrong type of cap. You can verify it by substitute it with solid tape (50mm) fixed with wire around the filling neck. Then the problem should be solved until the engine eventually boils over and destroys the tape.

Do you mean the screw cap on the outside, RHS? That one shouldn't spill coolant at all, AFAIK. (though I am not sure where the overflow pipe would be otherwise, if any) That said: are you sure you have a *coolant* cap on there? It is not uncommon to end up with a windscreen-washer cap....which does not have the pressure valve inside! (though not sure if it seals 100%, or has a continuous/non-pressure vent opening) Or perhaps you have too much coolant in the overflow bottle? > I guess the problem happens because with the engine stopped the pump > doesn't send the coolant to the radiator, so I give the engine on for 3 > minutes... but anyway it shouldn't hot so much with the engine stopped? The only smart solution is adding a coolant heater, which comes with its own electric pump, which you can then use for this 'after-cooling' effect. (burner itself won't activate if the coolant is already hot enough) (taxi's used to have only this pump, to circulate the warm coolant for interior heating) -- Bye, Willem-Jan Markerink The desire to understand is sometimes far less intelligent than the inability to understand [note: 'a-one' & 'en-el'!] To: Volvo303@yahoogroups.com From: "rebullet504" Date: Thu, 23 Apr 2009 14:23:47 -0000 Subject: [Volvo303] Re: Blowing coolant Reply-To: Volvo303@yahoogroups.com Hi, I got completely rid of my Blowing Coolant problem by adding the recommended amout of Water Wetter to the radiator.

Btw, the latter is not entirely true for the C3-series....the parts catalogue (Group 26 / Page 116/117) even mentions 3 different temperatures, 82/87/92C, and the latter is apparently dedicated to TGB20. (but TGB20 was also different from the other C3-models by having the stronger/larger clutch, while that, both as civil/C303 and in Malaysia, was combined with a larger radiator (3" vs 2")....still not sure if that applies to TGB20 too (Malaysia didn't call it TGB20, not even C306, but C304, despite being LWB 6x6 (yet also 4sp instead of 5sp)) Also, the comment with the '87C' cap in the manual suggests it superceeded an older model/partnumber....maybe that one was found to be faulty, in the long run? Other interesting detail in the parts manual: For 'MAL'(aysia), they list the same chain-with-protective hose that I had in mind too, to attach the outside filler cap to the body (for Malaysia/military probably just to avoid loosing it during service; my idea was to attach it to the door-hinge, so that it can't be opened with a locked car, to avoid theft, or even vandalism (throwing crap in there!).

Hmm....I am still a bit puzzled by this 740-turbo problem & solution....if there are boil-over problems, shouldn't it be better to change to an even *higher* pressure cap? Note that I am not sure whether the system in our Volvo's could even stand 1.5 bar instead of 0.75 bar....nor if it would/could solve anything if it gets really really hot (either by extreme ambient temperatures or by some other kind of thermal malfunctioning, as an emergency solution). > In the U.S. you can get a brand new .75 Bar cap from FCPGROTON for @ $5.00. > Here is a link to cap info > http://www.fcpgroton.com/product-exec/product_id/2125/nm/1985_1993_Volvo_24 > 0_Expansion_Tank_Cap/category_id/88 The green/1.5 bar cap is listed here btw: http://www.fcpgroton.com/product-exec/product_id/2238/nm/1985_1993_Volvo_240_Expansion_Tank_Cap/category_id/91 http://www.fcpgroton.com/images/products/large/9445462.JPG -- Bye, Willem-Jan Markerink The desire to understand=20 is sometimes far less intelligent than the inability to understand [note: 'a-one' & 'en-el'!]
