Replacing glow plugs, installing timer delay switch

[Monolithic]

The winter is coming here in Saskatchewan and my surf is not liking it at all. It usually takes about three turn overs of the key and a couple pumps of the peddle to get it going now. I'm guessing my glow plugs are shot so I ordered four Bosch ones from ebay and they should be here next week.

When I install the new plugs I plan to wire them up to a rocker switch installed on my dash and control my glow plugs that way so I can keep them on a little longer (because of -50C that will definitely be coming). I'm also going to install an inline radiator heater that will push the fluid through my engine keeping everything warm over night.

Anyway, I searched about other people doing something similar and found the user ridgerunner and his account of doing this http://www.hiluxsurf.co.uk/showpost....80&postcount=4

I searched other posts and couldn't find any more info about wiring a switch to control them manually. Is there anything I should know before doing this? Trying to cover my basis before I get way in over my head.

i would have fitted 2.8 3L glowplugs.

the reason being is the surf runs a super glow system. it uses lower voltage glows, gives them a short burst at 12v (very high heat), then switches over and run its through a resistor, which gives lower heat.

with a manual system you may end up running them to long at 12v and burn them out. the 2.8 glows afaik are a higher voltage and can take 12v for a much longer time. so you can sit it on the glows for a long time without burning the glows out.

3L Glow Plugs are the same voltage which is 11V. That's why the glow plugs system runs them at 10.5V. There are higher voltage in some other models, but they will not fit the 2.4 or 2.8.

I think if you install new plugs and have the heater installed it will work fine.

How about a sump heater? The oil resistance at those temps must be massive.

I just checked the Bosch listings - http://www.google.com.au/url?sa=t&rc...QSmJDOP6AiSKhg - and the GPT-142 glow plug has the same dimensions as the GPT-223 but is 16 volt. Now I know this will withstand battery voltage but not sure being 16 volt, will actually heat any better than the 11 volt GPT-223.

Next question will be where to find the GPT-142. I just searched and have no idea. Can't find any reference to them anywhere.

I bought a magnetic oil pan heater, but the shape of the oil pan doesn't really work it it. I can get it to stick on, but there's not really enough surface area on the heater to the pan to make a difference. I do only run 5w40 synthetic in it in the winter though.

I ordered glow plugs last week. http://www.ebay.ca/itm/120786859161?...84.m1497.l2649

These are the ones.

I have no trouble thinking the surf will start when the inline heater is plugged in, but if I have to drive my surf to work it could sit for up to 10 hours not being plugged in (I work construction and a lot of the time we don't have power). That is really my main reason for thinking of installing a switch.

Hi, please post how you get on with these plugs. I know it's a little milder here but i am ready for new plugs and was looking at these, being bosch they should be good but it is always nice to hear a review from some one who has fitted them.
Thanks

well bugger me. other Toyota gaff. a lot of super glow type systems run 9v glows.
16v glows are probably made for 24v engines.

in that case you should be able to put a manual switch to trigger the relay to hold the glows on full power for longer. having the after glow setup would be quite good for cold climates.
