Civic VX oil cooler.

[92civicvx]

Has anyone removed the lines going to the oil cooler to help warm up times or would you suggest not to? My car takes forever to warm up and with winter coming not trying to deal with that this year. My cooling system is fine(new rad, honda thermostat and rad hosed with new honda clamps, bleed coolant)

On heavy duty trucks the oil cooler is actually a heat exchanger tied into the coolant bypass, allowing the coolant and oil to warm up at the same rate.
If and when the 2 systems remain separate other wise it takes much longer for the oil to warm up then it does the coolant.

I don't know anything about civics, but if the oil "cooler" is tied into the coolant, leave it alone.
I have read on here that other people with cars that do not have oil heat exchangers have to drive up to 20 miles to start getting their best fuel economy, just enough time for the oil to get up to full temp.

Ya it's tied into the coolant. i guess I'll just leave it alone and get a block heater for the cold months.

I would try a more aggressive grill block during the winter. I recall Donkey CRX saying he has a hard time keeping his engine temperatures high enough for lean burn in his red VX, and that is with a full belly pan and near 100% grill block.

Here is the engine block heater knowledge repository:

Block Heater - EcoModder

Mostly just check out the ecomodder links at the bottom of the wiki page.
There is even one on there specific to a civic VX.

I've got the same problem with my turbodiesel. Servicemen have told me that the closed grille block will cause the oil to overheat (no breeze on the oil/air cooler), but even with an engine tray, insulated hood and even an insulated oilpan, the engine still does not reach full operating temp when it is below -5 or -10 deg C outdoors.

92civicvx: If your engine cools the oil with coolant, then don't touch it. If it cools with air, then make an openable grille block - that way you won't lose heat when the grille is closed, yet you can still open it when cooling is needed.

I don't remember seeing an oil cooler on my VX.

Sounds like this is technically an oil warmer. Is that the case? I don't think it would be wise to try to out think the honda engineers in this case.

I highly recommend a block heater. I use it year round and right now with the mornings around 40-50°F i can hit 150°F coolant in about 2 min. This is with a 400w GM heater on for about 2.5 hours

The VX and HF both have these and since these engines run leaner than the rest of the D series engines, they actually help maintain a steady engine temperature.Reducing detonation and overheating. I installed one in my old beater (D16A6) and was able to extend my oil changes by 2000 miles.

I would try the grill block before spending any money...
