Locations for water temp / oil sensor installation?

Post by **NafemanNathan** » Fri Feb 01, 2013 1:54 pm

Just had a thought with the water temp sensor as well. I've got a spare head rad hose connector (the one that bolts on to the head) that I was going to get powder-coated with a few other engine bits. Well before painting I could get a boss welded on the side of it to accept the sensor. Would look a lot nicer as I never really liked the thought of chopping my top hose in half.

That is an idea! I have a few spare engines kicking around at the mo

Although wouldnt the rubber of the hose act as a kind of heat isolator? Connecting directly to the metal your picking up the extra engine heat?

True true. Hondata thermal styley gasket then?!

Having looked at the sensors for oil temp I dont think having my existing sandwich plate tapped in the side for two extra 1/8" connectors isnt a goer. The sensor is too long for that:

Where would it go?

I do think the easiest option is to get a non-thermostatic plate (£31) and place it between the engine and my thermostatic plate. Then get 1/2" to 1/8" adpters for the oil pressure and temp sensors. There is talk on other forums of people having to use two plates together (in/out, turbo feed, temp/pressure sensors). My only worry is that this setup would be too tall and hit off the fire wall.

I could get around the height issue by installing a relocation kit but 3 sandwich plates is getting silly

I agree, there isn't alot of space there (on the 5th gen anyway). If I was you I would get a sump plug adaptor and get the temp from there and then for oil pressure I would run an t-piece on an extension so that you can keep the oil pressure light. Just make sure you keep the wiring out of harms way. Taping the metal that the top hose goes onto is another way of getting coolant temp.This was the way it was done on my old civic.

My other thought was to use two of these kind of things to replace the two male/male AN- fitting here...

But otherwise, why would you need 3 sandwich plates if you went for an oil filter relocation?

Were you using a long or shortie filter? I thought about the sump plug as a place I could use but we thought that I wouldnt get an accurate reading from there. The extra sandwich plate solves both temp and pressure needs easily.

Nathan, that is what I am on about using two of the sandwich plates, one normal and the other thermostatic. The non-thermostatic would be connected to the block so that the oil pressure and temp sensors get the best reading and are always in contact with the circulating oil directly from the engine. The thermostatic plate goes on top, and regulates oil flow to the cooler. Then the oil filter sits atop all of that.

If that setup is too tall I would replace the oil filter with a relocation kit (which is shorter then the filter). The oil filter could then be situated somewhere out of the way.

Ah I see. Sorry my thermostatic valve is situated along the lines somewhere. Didn't realise yours was a plate. Got any pics of it?

That is it above ^^ the thermostat is built into the plate. The spring at the back end of it is connected to the thermostat, and opens the valve. http://www.merlinmotorsport.co.uk/p3482 ... _info.html

Oh ok. Have you got any pics of both sides of that thing?
