Im about to fit a Mocal 16 row cooler but not quite sure what to do with the original heat exchanger coolant lines. I'm talking about the coolant pipe running from the standard heat exchanger to the rad and the one running up to the top rad hose. I was thinking i would just blank the one off that goes too the top hose and remove the one going to the rad as I'm planning to fit a new Rad that doesn't have that outlet. any help appreciated Tom |

I have left mine on as it it helps with the warm up cycle and when hot it transfers heat from oil to water so double bonus road driving or track |

Mine is also left on. Beware of a few mocal 16 rows with leaking cores. Mine was one of them.________________________________________ DIABLO GTI-6 - Legend - NILE GTI-6 - SoldCHERRY GTI-6 P1 SUPERCHARGED - Broken up BLACK RALLYE - Sold 205 Dturbo xud9 work horse - Dead CHERRY RALLYE - new toy |

I would deffo remove the original heat exchanger. It makes fitting the cooler a lot harder but I found it doesn't didn't really work that well otherwise.I've just joined the original water pipe to another running down to the radiator. ________________________________________ Nothing to see here |

Yeah I still don’t understand how having both is going to work the heat exchanger will just keep the oil cooler and stop the thermostatic sandwich plate from operating correctly so therefore you won’t have flow through the oil cooler?? Or am I not understanding this correctly?? |

im using a thermostatic sandwich plate it only diverts oil to the cooler when oil is above 90c ishremember the existing cooler can also transfers heat from water to oil too cooling the block |

its common practice on rally cars to retain both as the coolant always gets to temp faster than oil, which with a heat exchanger can bring the oil up to operating temp a lot quicker, which is a good idea for engine efficiency.when the oil gets hot it works the other way and dumps heat into the rad, obviously when used very hard there isnt the capacity there to get rid of the excess heat so an additional air to oil exchanger is used. ________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |
