    Hey! I'm replacing the coolant tank(and thermostat) on my NC (08) as the tank decided to explode the fluid all around the engine bay! Find a new tank was a pain in the a*se to start with so i've opted for an aluminum one: https://fab9tuning.com/moroso-coolant-overflow-expansion-tank-nc-06-15/...

    Hi there, just posted a sorta build thread/intro in members rides. Ive come across a sorta leak is what i can only presume. Its from the back end of the engine and looking at further exploded pictures i suspect its to do with water thermosensor/heater hose. Personally i think its down to...

    Hey all, I have no idea what coolant is in my system at the moment (probably none as I've been topping up with just water recently) so can I just buy any old coolant and add it to the system? Or am I right in thinking that some coolant types don't mix with other coolant types? I'm just...

    Hi All, I've just had the headgasket done and am looking to find out if the thermo sender is duff - because my dash temp gauge currently reads near the 1 o'clock position....the same as when the car overheated before the hg went! So using an infrared thermometer I measured the temperature of...

    This car is street driven. Mods in my signature pertain to the car. So I noticed my water temps going up to around 110c and thought, new thermostat and flush. After no luck I decided to just take care of the other culprits, being the pump and radiator...still running hot. Now the funny thing is...

    Hi all, Hoping you can help me out.. I've got a 1991 Roadster that has started leaking coolant from the front of the engine. There appears to be a crack in the engine that is then dripping down onto the belts. This is then sending the coolant flying over the entire engine bay. The coolant is a...

When the thought came to me is there any harm in using motorbike coolant. ive been a biker for 6 years and i know bikes use alloy rads so it got me thinking. I know it'll cost alot more but is there really and...

    Evening gents, New to the forum and first post, so here it goes. I have recently picked up a 1994 MX-5 1,8 here in CH. 150,000km on the clock and generally clean. Few issues to sort before presenting her for the infamous MFK (Swiss MOT). Other issues I'll post in separate threads, but for now...

    So I'm looking into changing all of the hoses in the engine bay of the 5 for silicone numbers, as I fear some of the rubber ones might be over the hill and just itching to pop. I've looked at the full set on mx5parts, sounds good as they remanufactured the original OE rubber hoses in fetching...

    I was scrolling through Jay Leno's Garage and watched part where there is some one from Evans cooling presentating their product. It was moment of "oh my why have I not heard from this before" This seems to be extremely good product, only downside is the price. Truckdrivers have used this years...

    Hey Guys I'm pretty sure I've diagnosed the fault, but I wanted to see if anyone on here has had or knows about these symptoms, before I start draining coolant and taking the system to pieces (again)! Once up to temperature, I've noticed a small leak (well, occasional drip) coming from where...

    Does anybody know whether the bottom rad hose from the Mk2 will fit a Mk1? It seems a bit pointless having the metal joint in the middle when you could easily enough have the one hose...
