Posted: Thu Sep 18, 2014 11:29 am Post subject: Were to mount External Oil Cooler |
|
|
I am planning my next project and need some help. I have a 1964 Type I with a 1600cc SP stock engine in it but I need a little more cooling in the summer due to highway speeds and 100+ temps. I have a all the tin on it and aeverything works fine but it is a convertable and has deck lid venting and I think that is my nemisis right now. The engine keeps getting too hot and I have to slow down. I am researching external oil coolers due to mine having a internal oil cooler. I do not have a dog house cooler. Has anyone mounted the actual system in their a bug and were did you put the actual cooling fins?
One thought was under the back hump above the tranny but not alot of air gets there.??? Any other ideas.
While at it I will prpbably add a oil filter also. _________________ "Sic Vic Pacem, Para bellum - Pray for peace, prepare for war."

My 1971 Convertible runs 1835cc DP engine in Arizona. I didn't have a doghouse shroud/cooler, so I use engine lid standoffs and an external oil cooler located on the hidden side of the fan shroud, used this system 38 yearsnow in heat worse than Kansas.
Several on this board say that kind of cooler is a death sentence even with 1600cc, but my experience is otherwise.
There's also the tennis ball trick for highway driving to keep the bottom of the engine lid open.
Yes, convertibles have less venting than sedans. _________________ 1970 VW (owned since 1972) and 1971 VW Convertible (owned since 1976), second owner of each.

I would try and find the issue as to why you are running hot, I dont know to many people who run external oil coolers on stock motors.The only time I have ever needed an external oil cooler is when I run a 2ltr with higher compression. I mount them on the bottom of the package tray hanging about 2-2 1/2 inches down. I use the fan assisted coolers. _________________ Ethan Dunlap

I have always thought that stock was best but recently driving 30-60 minutes at 60-70 MPH with a freeway flyer tranny it has been getting too hot and the Gene Berg's Temperature Dipstick light starts to comes on until I slow to 50-55. It has only been when high humidity and high temps area in abundance but it has happened. I have stand-off plates but hesitate to use them due to the verts top covering it when down. I must admit I did know about the tennis ball trick but did not use it. I will use it immediately until I get more cooling. _________________ "Sic Vic Pacem, Para bellum - Pray for peace, prepare for war."

like ConcreteAce said, I mounted my external oil cooler under the parcel tray and used a fan mounted cooler. I run a 2007 cc in my 61 bug and in Houston summer weather, my car runs at 175 degrees all day . You can find plenty of external oil cooler on this site for cheap. I have a hi-performance cooler sitting on my shelf if you are interested. I can get make and model of it if you'd like. |

I can get one I think but I am in the planning phase right now. When I drop my engine this winter to get he leaks fixed I will do it. If you could get the make and model you use that would help. I found alot of them on line but they all seem the same except for how many lines they have or if they are fan asisted. I assume more is better for cooling.
Now that we are talking about fan assisted do they need a dedicated cuicuit? Do they come with a temperature gage that will turn the fan on and off or do they run all the time? Are they loud if under the package tray?
Thanks for the help. _________________ "Sic Vic Pacem, Para bellum - Pray for peace, prepare for war."

Dog House Cooler and fan
Propped Deck Lid (even with the slots)
Directional vanes in fan housing
VERY important: include the Hoover Bit on the bottom of your doghouse oil cooler. _________________ "Honesty hath no fence against superior cunning" |

That's exactly right Max, i have a Setrab oil cooler. they are made for race cars and proven. Before i got the Setrab, i have already purchased an Empi cooler. Hadn't had any problems. It did came with the fan and temp gauge so it kicks on at 180 degrees. Easy to mount and wire, did it all myself. I found a topic on here on how to mount it and wire it on another forum (i think it was the bus forum). |

Here, but my swing axle car is far from stock, there's a ton of shit crammed under the parcel tray. Here's the cooler
Here's the thermostatic adapter, and tee that holds the fan switch
Here's the cooler
And the fan
My car runs a bit hot with just the stock cooler, but it's 2161cc's. With this added it is very stable. |
